I have a Bosch Exxcel 7 washer that has started causing a water hammer on the final spin cycle. This started after I changed the brushes so may be because something got disturbed when the washer was lying on its front. Having a good investigate with the cover off, the solenoid on the water inlet valve is being operated in about 1sec pulses which is causing the water hammer, it's also leaving water in the conditioner part of the detergent drawer. So something is momentarily switching the inlet valve solenoids. Does anyone have an idea of where I should look next? Getting the Bosch engineer out is something I'd rather not have to do, given that it's well out of warranty! Nick
