I was getting error code of four flashes and the symptons of not being able to complete a spin. I replaced the brushes and now realise I hadn’t witnessed the full set of symptoms. (I had run the spin cycle only to test the error code.) On attempting a full wash cycle the water doesn’t fill to the required level, the wash cycle is shortened and erratic, the above (not spinning properly and four flashes) is still happening. Does this sound like I need to replace the PCB or is it time to look for a new machine. The one is about 13 years old and so far given no trouble. Any advice would be welcome – so thanks in advance.
