F01 means “motor triac short.” The triac is an electronic component on the PCB that controls power to the motor. The error indicates the PCB is logging a problem with this component or its associated circuit. However, the technical manual also instructs checking connections, which means a wiring or connector fault can produce F01 without the triac itself having failed.

Not without checking connections and the motor first. At least one confirmed case of F01 was caused by poor connections in the motor plug rather than a PCB fault. Replacing the PCB without eliminating connection and motor faults is an expensive gamble that may not resolve the issue. Check connections and motor continuity first, then consider PCB testing or replacement only if those checks find nothing.

Yes, but it requires electronic knowledge to diagnose correctly. Most appliance engineers are trained to replace PCBs rather than repair them, and testing the triac specifically requires electronic test equipment. A specialist PCB repair company can test and repair the board if the PCB itself is confirmed as the fault. An engineer visit is the recommended route for this fault to avoid speculative parts replacement.

SE means the machine has detected a motor fault. LG’s technical guidance suggests the cause could be the motor itself or the main PCB, and recommends checking the motor first. The error does not specify which component has failed – diagnosis requires testing connections, carbon brushes (if fitted), and motor windings before considering whether the PCB is at fault.

Not without testing it first. Motors are expensive and SE can be caused by a wiring connection fault or worn carbon brushes rather than a failed motor. Test the motor connections, check the brushes if the motor has them, and test the motor windings with a multimeter before ordering any replacement parts.

Yes – LG’s technical documentation lists the PCB as a possible cause alongside the motor. However, the guidance is to check the motor first because motor faults are more common and because a PCB fault is only confirmed once the motor and its connections have been eliminated. Do not replace the PCB speculatively.

E50 is a customer-facing motor group error code. It indicates a fault within the motor system but does not specify which component has failed. In engineer diagnostic mode the machine will display either E51 (motor power triac short circuit) or E52 (no signal from the motor tachometric generator), each pointing to different components. E50 alone is not enough information to order replacement parts.

Not without specialist diagnostic equipment to read the full underlying error code. Even once E51 or E52 is confirmed, the repair involves testing PCB components and motor circuits that require technical knowledge and a multimeter. Replacing the PCB or motor speculatively is expensive and may not resolve the fault. An engineer visit is the recommended approach.

Not necessarily. E51 (the more likely underlying code when E50 is displayed) relates to the motor power triac on the PCB – a PCB component – not the motor itself. The motor may be entirely functional while the PCB has failed. Alternatively, a motor fault may have caused the triac to fail. Both possibilities need to be investigated before concluding which component requires replacement.

Error 7 means the machine is sending power to the motor but cannot detect that the motor is actually turning. This is reported as “motor jammed / drum shaft jammed / tachometric generator fault.” The machine knows the motor circuit is complete but has no speed signal returning from the tacho generator. Test whether the drum turns freely by hand first – if it does, the fault is in the tacho system rather than a physical jam.

Two indicator LEDs on the control panel flash in a repeating sequence – typically the Start/Pause and Delay Start lights. Count the number of complete flashes before the sequence pauses and repeats. That number is the error code. Error codes are specific to the Nextra range – the same flash count has a different meaning on other Hoover models or other brands.

The initial hand-test of the drum is straightforward and safe. If the drum turns freely, inspecting the tacho magnet on the motor is also accessible for someone confident with basic appliance investigation. However, testing the tacho coil requires a multimeter, and bearing or motor replacement requires disassembly – both are more appropriate for an engineer. If the drum is jammed, the cause and repair depend on which component is seized, which requires an engineer to assess safely.

The Start and Pause LEDs flash together in a repeating sequence. Count the number of flashes in one complete cycle before the sequence pauses and repeats – that number is the error code. Count within a 15-second window. If the lights appear lit but are not flashing, this may indicate error 0.

Some codes point to straightforward checks – error 2 (filling timeout) is worth checking the water supply and inlet filter first, and error 3 (drain timeout) is worth checking the pump filter and drain hose. Others, such as errors 0, 6, and 9, involve expensive PCB components that should not be replaced speculatively. Always test the most likely simple cause before ordering parts.

Both relate to the motor not being detected as running. Error 7 is documented as motor jammed, drum shaft jammed, or tachometric generator fault. Error 8 is similar and may indicate a sensor fault rather than a mechanical jam. The diagnostic approach is the same – test whether the drum turns freely by hand, and if it does, investigate the tacho system. See the individual guides for each code for full diagnosis steps.
