Hi I have a Bosch dishwasher SGV43A03GB which is about 4 years old. It has worked very well until recently - the wash quality is now very hit and miss, sometimes getting everything spotless, other times leaving deposits especially on the top rack. I've tried using dishwasher cleaner and have disassembled the spray bars and checked there is no blockage or scale, manually cleaned out any grease build ups etc but still can't work out what's wrong. The one thing I noticed is if I put it on the prewash cycle and pull the door open whilst it's wasing, the bottom rotor is spinning but the top one isnt although water is coming out of the rotor bar. It is free to move and as previously mentioned has been cleaned and I am sure there are no blockages. I have removed the grey plastic trunking between the bottom of the dishwasher to the top and it is definitely not blocked. Once the trunking is removed it is evident that the bottom and top rotors are fed from different channels. Does this indicate a problem or is it that the program selects the top rotor at different times to the bottom rotor or should they always operate simultaneously ? If it indicates a blocked pump is this possible to look at in-situ ? This model is built in so is a fair amount of work to remove from the worktop. Any advice or tips welcome !!
