Several error codes on Hotpoint Aquarius washing machines are indicated by flashing lights. These are just basic ones from models WMA30, WMA31, WMA32 & WMA33 although they may be the same for other Hotpoint Aquarius models using led lights. Aquarius models with a proper digital display should indicate error codes in a more sophisticated manner using actual text such as F1..
The door locked light is flashing
.. This one is simple, and you should be to work it out yourself. If the door locked light is flashing then the door is not properly shut. If by any chance the door is properly closed but the door locked light is still flashing then there may be a fault on the door lock or somehow the door lock is not being properly activated when the door closes. When the door closes the door catch should fit inside and operate something inside the door lock which activates the lock. (How does a washing machine door lock work?)
Wash light is flashing
This should only happen if someone turns the wash selected dial after the wash has started. Maybe a child is messed with it? The light should stop flashing at the end of the programme.
Pre-wash light is flashing
This indicates a filling fault. The software in the washing machine believes that the correct amount of water has not gone into the machine during the maximum time allowed. The first things to check are that the tap hasn’t been left turned off, or there are no kinked hoses etc. For full diagnostic on fill faults check here – not filling with water
The end light is flashing
The end light flashes when the washing machine has been paused. Hopefully pressing start/cancel should get it running again. If not try cancelling the program and starting again.
Final spin light flashing
The manual says this is not a fault but although that’s technically true something has clearly gone wrong. It would be helpful if manufacturers had a special light for out of balance load detected because unless familiar with the instruction manual people will not understand what has gone wrong. Basically the out of balance detection system hasn’t been satisfied that the load inside is safe to spin and therefore no final spin has occurred.
In this situation you should find your laundry sopping wet, and clearly many people might interpret this as washing machine breakdown. This should only be an occasional occurrence. For full details on out of balance detection and how to load the washing machine properly read my articles here – Spin light flashing at end of the cycle
All lights flashing
This indicates a critical error. The wash cycle has been abandoned. Unfortunately this is one of those faults with no easily identifiable cause. The technical manual implicates potential faults on the motor, pump, drain hose and associated plumbing, pressure switch, pressure chamber and presumably many potential connection issues too. If this is a one-off occurrence, keep fingers crossed and keep an eye on the machine. Otherwise call an engineer (Find appliance engineers).
