Blomberg Washing Machine Error Codes
Blomberg washing machines display error codes as E followed by a one or two-digit number — E1, E2, E3, E11 and so on. Some Blomberg models also display H codes (H1, H2, H3 etc.), which are engineer-level diagnostic codes giving more specific component-level information. Find your code in the tables below. Blomberg shares its manufacturing platform with Beko under Arçelik ownership, so the codes are identical across both brands.
Which Blomberg machines does this guide cover?
This guide covers all Blomberg washing machines and washer dryers sold in the UK, including the WNF, WMT, WAF, WMF, KEF, and LRF washer dryer series. Blomberg is positioned as a premium-tier brand within the Arçelik group and shares its manufacturing platform with Beko, Grundig, Leisure, and Flavel. Higher-end Blomberg models feature the Optima Inverter Motor (a brushless induction motor) — this matters for diagnosing motor fault codes, as machines fitted with this motor do not have carbon brushes.
E codes are what most users see when something goes wrong — E1, E2, E3, E11 and so on. They identify the general fault category (door, heating, drain, motor) but do not always pinpoint the specific component. These are designed to be informative for the user without requiring engineer-level diagnosis.
H codes (H1, H2, H3, H11) are accessed via the machine’s service mode and provide more precise component-level diagnosis. They identify exactly which sensor, switch, or component the control board has detected as faulty. Some Blomberg machines display H codes directly when certain faults occur.
Blomberg is owned by Arçelik and produced on the same manufacturing platform as Beko, Grundig, Leisure, and Flavel. The error code systems are largely identical across all of these brands. If you cannot find your Blomberg code fully detailed here, cross-referencing with our Beko washing machine error codes guide is worthwhile.
Older Blomberg machines without a digital display use combinations of indicator lights to signal faults. The pattern of which lights are on, off, and flashing identifies the fault category. Cross-reference with the E code table below.
Blomberg E codes: complete reference
The following codes apply to Blomberg washing machines and washer dryers with a digital display.
| Code | Fault description | Most likely causes | Check first |
|---|---|---|---|
| E01 / E1 | Door lock fault — machine not detecting the door is closed and locked | Door not fully closed. Failed door interlock mechanism. Wiring fault to the PCB. Obstruction in the door seal. Broken door handle or catch. | Open and firmly close the door, ensuring nothing is trapped in the seal. If the door closes correctly and E01 persists, test the door interlock for continuity. Door interlock replacement is one of the most common Blomberg repairs — genuine parts are available through our spare parts section. |
| E02 / E2 | Heating fault — water not reaching target temperature | Failed heating element. Failed NTC thermistor. Wiring fault between element or thermistor and control board. Limescale heavily fouling the element in hard water areas. Control board fault. | Test the heating element for continuity with a multimeter — open circuit confirms failure. Test the NTC thermistor — approximately 4,700 ohms at 25°C on Blomberg machines (using the same Arçelik component as Beko, which is lower than the 30,000 ohm sensors used by some other brands). In hard water areas, run a descaling cycle before testing components. |
| E03 / E3 | Drain fault — machine unable to drain water within the expected time | Blocked pump filter (the most common cause). Kinked or blocked drain hose. Standpipe too high. Foreign object blocking the pump impeller. Failed drain pump motor. | Clean the pump filter — behind the small access panel at the bottom front of the machine. Place towels and a shallow tray in front before opening as water will flow out. Unscrew anticlockwise, remove all debris, check the pump cavity for foreign objects, and refit firmly. See our full guide: washing machine not draining. |
| E04 / E4 | Water inlet / fill fault — machine not filling within the expected time | Tap closed or partially closed. Kinked or trapped inlet hose. Blocked inlet hose filter. Low mains water pressure. Failed inlet valve solenoid. | Confirm the tap is fully open. Straighten the inlet hose. Unscrew the inlet hose from the back of the machine and clean the small mesh filter inside the inlet port. |
| E05 / E5 | Pressure switch fault — water level sensor reading incorrectly | Failed pressure switch. Blocked or kinked pressure switch hose. Soap suds blocking the pressure system. Wiring fault to pressure switch. | Check the pressure switch hose — a narrow pipe running from the drum to the pressure switch — for blockage or kinks. Run a service wash to clear soap residue. Test pressure switch if hose checks are clear. |
| E06 / E6 | NTC thermistor fault — temperature sensor not reading correctly | Failed NTC thermistor. Loose or corroded wiring connector to the thermistor. Limescale on thermistor in hard water areas. | Test the NTC thermistor with a multimeter — approximately 4,700 ohms at 25°C on Blomberg machines. Open circuit confirms failure. In hard water areas, run a descaling cycle before testing as limescale on the sensor can produce this code without the thermistor failing. |
| E07 / E7 | Motor or triac fault — motor circuit fault | Worn motor carbon brushes (collector motor models only — not present on Optima Inverter Motor models). Failed triac on control board. Wiring fault. Motor winding failure. | With the machine unplugged, check the drum rotates freely by hand. On models with a conventional collector motor, inspect the motor carbon brushes and replace if worn below 10mm. On Optima Inverter Motor models there are no brushes — engineer diagnosis is required for sensor and inverter board testing. |
| E08 / E8 | Motor fault / tachometer error | Failed tachogenerator. Worn carbon brushes on collector motor models. Wiring fault between motor and control board. Motor failure. | Check carbon brushes first on collector motor models. Test tachogenerator resistance (typically 100 to 200 ohms — open circuit confirms failure). |
| E09 / E9 | Door interlock fault — variant code | Failed door interlock. Wiring fault between interlock and PCB. Door not fully closing. | Same checks as E01. Some Blomberg models use E09 rather than E01 as the primary door lock code. |
| E10 | Door lock or control fault | Door interlock fault, control board fault, or wiring fault between the two. | Check door closes correctly and test interlock. If both are good, the fault is in the wiring or control board. |
| E11 | Motor fault or unbalanced load detected during spin | On some Blomberg models: motor fault — engineer diagnosis required. On others: unbalanced load detected, machine has paused the spin cycle for safety. | If the load is uneven, redistribute the laundry around the drum and restart the spin. Adding a towel alongside a single heavy item helps balance the load. If E11 persists with a balanced normal load, motor diagnosis is required. |
| E13 | Water leak detected (anti-flood / Aquastop) | Water leakage detected by the anti-flood system in the machine base. Internal leak source — door seal, pump housing, internal hose connection. | Check the area around the machine for visible water. Tilt the machine slightly backward to drain any water from the base tray. Investigate the leak source before using the machine again. |
| E17 | Motor fault / inverter board fault on Optima Inverter Motor models | On collector motor models: similar to E07/E08 motor fault. On Optima Inverter Motor models: inverter board fault or motor speed sensor fault. | On collector motor machines, check carbon brushes first. On Optima Inverter Motor machines, engineer diagnosis is required for inverter board or speed sensor testing — there are no brushes to check. |
| E18 | Various — model dependent | Varies between models — refer to the instruction manual for the specific meaning, or check the H code via service mode for more precise diagnosis. | Engineer diagnosis recommended given the model-dependent nature of this code. |
Blomberg H codes: engineer diagnostic reference
H codes are component-level diagnostic codes that identify the specific sensor, switch, or part the control board has detected as faulty. They provide more precise diagnosis than the consumer E codes and are typically displayed when entering service mode or when certain specific faults occur.
| H code | Fault description | Most likely causes | Check first |
|---|---|---|---|
| H1 | NTC thermistor open or short circuit | Failed NTC thermistor. Wiring fault to the thermistor — open circuit (broken wire) or short circuit (insulation breakdown). | Test thermistor resistance (approximately 4,700 ohms at 25°C). Inspect wiring to thermistor for damage or loose connectors. |
| H2 | Heater detected open circuit — failed heating element | Failed heating element with internal break. Wiring fault between element and control board. Loose or burnt-out element terminal connection. | Test heating element for continuity with a multimeter. Open circuit confirms element failure. Check element terminal connections. |
| H3 | Heater detected stuck on / heater triac short circuit | Failed heater triac on the control board causing the element to remain on continuously. Element relay stuck closed. | Engineer diagnosis required. Triac and relay faults on the control board are not DIY repairs in most cases. |
| H4 | Inlet valve triac short circuit | Triac controlling the water inlet valve has failed. | Engineer diagnosis required. Test inlet valve solenoid first to rule out a valve fault. |
| H5 | Pump open circuit — failed drain pump or wiring fault | Failed drain pump motor. Open circuit in pump wiring. | Test drain pump for continuity with a multimeter. Open circuit confirms pump failure. Check wiring connector at the pump. |
| H6 | Motor triac short circuit | Failed motor triac on the control board. May also cause the machine to trip the RCD. | Engineer diagnosis required. If the machine is also tripping the electrics, the triac is the likely cause. |
| H7 | Pressure sensor failure | Failed pressure switch. Wiring fault. Blocked or disconnected pressure switch hose. | Check pressure switch hose for blockage or disconnection. Test pressure switch if hose is clear. |
| H8 | Tachometer / motor speed sensor fault | Failed tachogenerator. Wiring fault. Worn carbon brushes on collector motor models. | Check carbon brushes first on collector motor models. Test tachogenerator resistance if brushes are good. |
| H11 | Motor or tachogenerator open circuit | Open circuit in motor windings or tachogenerator winding. Wiring fault. Disconnected motor connector. | Check motor wiring connector at both motor and PCB ends. Test motor windings and tachogenerator for continuity. |
How to clear a Blomberg error code
Many Blomberg error codes can be cleared with a simple reset once the underlying fault has been resolved. The standard reset procedure is to hold the START/PAUSE button down for approximately 3 to 5 seconds. The machine cancels the active programme and clears the displayed code.
For a deeper reset, switch the machine off at the wall socket, wait at least 60 seconds, and switch back on. This clears any stored transient codes and allows the machine to restart its diagnostic cycle from a clean state.
Important: clearing the code does not fix the underlying fault. If the same code reappears as soon as you restart the cycle, the fault is genuine and needs to be diagnosed and repaired. Clearing the code is only useful to confirm whether the fault is consistent or transient.
What to check before calling an engineer
-
Power cycle the machine. Switch off at the wall socket, wait 60 seconds, and switch back on. Many transient Blomberg error codes clear on a power reset. If the same code returns consistently, it represents a real fault.
-
Clean the pump filter (E03 drain code). The filter is behind the small access panel at the bottom front of the machine. Place towels and a tray in front before opening. Unscrew anticlockwise, remove all debris including coins, check the pump cavity, and refit firmly. This single check resolves the majority of E03 faults.
-
Check the door closes correctly (E01 / E09 / E10 door codes). Open and firmly close the door, ensuring nothing is caught in the door seal. If the code persists, test the door interlock for continuity.
-
Check the water supply (E04 fill code). Confirm the tap is fully open, the inlet hose is not kinked, and the inlet filter mesh inside the inlet port is clean.
-
Descale the machine (E02 / E06 / H1 temperature codes in hard water areas). Run an empty cycle on the hottest programme with a proprietary descaler before testing or replacing the heating element or thermistor. Limescale on the thermistor can produce false readings without any component actually failing.
-
Check carbon brushes (E07 / E08 motor codes on collector motor models). With the machine unplugged, check the drum rotates freely by hand. If it does, inspect the motor carbon brushes and replace if worn below 10mm. Important: this applies only to collector motor models — Optima Inverter Motor models have no brushes.
-
Redistribute the load (E11 unbalanced code). Open the door and spread the laundry evenly around the drum before restarting the spin. Adding a towel alongside a single heavy item helps balance the load.
Always switch the machine off at the wall socket and unplug it before accessing the pump filter, opening any panels, or inspecting internal components. Never work on electrical components with the machine connected to the mains. See our DIY appliance repair safety guide.
Can I fix a Blomberg error code myself?
Straightforward to check or fix yourself
Cleaning the pump filter (E03 drain code). Checking and cleaning the inlet hose filter (E04 fill code). Checking the door closes correctly and testing the interlock (E01, E09, E10). Replacing the door interlock on confirmed failure. Power cycling to clear transient codes. Descaling for temperature codes in hard water areas (E02, E06, H1). Replacing motor carbon brushes on collector motor models (E07, E08, H8). Redistributing the load (E11 unbalanced). Replacing the heating element on confirmed failure (H2). Replacing the drain pump on confirmed failure (H5).
Requires an engineer or advanced competence
Triac faults on the control board (H3, H4, H6). Inverter board faults on Optima Inverter Motor models (E17, E18). Pressure sensor faults if hose checks are clear (E05, H7). Water leak investigation (E13). Motor and tachogenerator faults if brushes are not the cause (H11). Any control board fault. Any fault that persists after all basic checks have been completed.
Blomberg, Beko, Grundig, and Leisure: shared platform
Blomberg is owned by Arçelik and produced on the same manufacturing platform as Beko, Grundig, Leisure, and Flavel. The brand sits at a more premium tier than Beko within the same group, with higher-specification component choices on equivalent models, but the underlying control systems and error code structures are identical across all of these brands.
This means an E03 on a Blomberg machine is the same fault as an E03 on a Beko machine, with the same diagnosis steps and replacement parts. If you cannot find your Blomberg code fully detailed in this guide, our Beko washing machine error codes guide covers the same code system in further depth and the information is directly applicable to your Blomberg machine.
Despite Blomberg’s German heritage branding, modern Blomberg washing machines are produced in Turkey at Arçelik manufacturing facilities alongside Beko. The brand was acquired by Beko in 2002 and the German engineering positioning reflects design and quality standards rather than country of manufacture.
Blomberg error code pointing to a fault you cannot resolve?
If basic checks have not cleared the fault, a qualified engineer is the right next step. We cover Blomberg washing machine repairs nationwide with genuine spare parts available for most models including door interlocks, drain pumps, heating elements, NTC thermistors, and carbon brushes.
Frequently asked questions about Blomberg washing machine error codes
What does E03 mean on a Blomberg washing machine?
E03 is a drain fault — the machine has been unable to drain water within the expected time. In the vast majority of cases the cause is a blocked pump filter rather than a failed pump. The filter is behind the small access panel at the bottom front of the machine. Cleaning it takes around five minutes and resolves most E03 faults without any parts or engineer visit. If the filter is clear and E03 persists, check the drain hose for kinks then test the drain pump motor.
What does E01 mean on a Blomberg washing machine?
E01 typically indicates a door lock fault — the machine is not detecting that the door is properly closed and locked. First confirm the door closes fully with nothing obstructing the seal. If it closes correctly and E01 persists, the door interlock has likely failed and requires replacement. Door interlock replacement is one of the most common Blomberg repairs and genuine parts are widely available for most models.
What is the difference between E codes and H codes on Blomberg machines?
E codes are consumer-facing display codes that identify the general fault category — door, heating, drain, motor — but do not always pinpoint the specific component. H codes are engineer-level diagnostic codes that identify the exact sensor, switch, or part the control board has detected as faulty. H codes provide more precise diagnosis. They are accessed via service mode on most Blomberg machines and sometimes display directly on certain faults. If you have access to the H code, it is more useful for diagnosis than the E code alone.
How do I clear an error code on a Blomberg washing machine?
Press and hold the START/PAUSE button for approximately 3 to 5 seconds to clear the code. For a deeper reset, switch the machine off at the wall socket, wait 60 seconds, and switch back on. Important: clearing the code does not fix the underlying fault. If the same code reappears as soon as you restart the cycle, the fault is genuine and needs to be diagnosed and repaired.
Are Blomberg and Beko washing machine error codes the same?
Yes. Blomberg is owned by Arçelik and produced on the same manufacturing platform as Beko, Grundig, Leisure, and Flavel. The error code systems and diagnosis steps are largely identical across all of these brands. An E03 on a Blomberg is the same fault as an E03 on a Beko, with the same parts and the same fixes. Our Beko washing machine error codes guide covers the same code system and applies equally to Blomberg machines.
Does my Blomberg washing machine have carbon brushes?
It depends on the model. Higher-end Blomberg machines feature the Optima Inverter Motor — a brushless induction motor with no carbon brushes to wear out. Standard Blomberg models with conventional collector motors do have carbon brushes. Check your model specification to confirm which motor type is fitted. Motor fault codes (E07, E08, H8) on collector motor models point primarily to worn brushes; on Optima Inverter Motor models there are no brushes — the speed sensor or inverter board is the likely cause and engineer diagnosis is required.
Are Blomberg washing machines made in Germany?
No. Despite Blomberg’s German heritage branding, modern Blomberg washing machines are produced in Turkey at Arçelik manufacturing facilities. The brand was acquired by Beko (Arçelik) in 2002 and the German engineering positioning reflects design and quality standards rather than the country of manufacture. The original Blomberg factory in Germany was closed when production was consolidated to Arçelik facilities.
