    We have a Bosch dishwasher that is driving us crazy. Basically it washes fine on the lower deck, but the upper deck stuff comes out covered in gritty bits.

    Further investigation reveals that there is water going to both rotors but only the bottom one is turning.

    Can anyone help??

    Thanks,

    Jonathan

    check top arm and water passage to it for blockage/s..also possible low water level or weak/failing main circulation motor.

    Chaps,

    I have taken the upper rotor apart, it moves freely in my hand and there are no blockages in that part of the system (I have looked down the tube), indeed when I open the door quickly I can see loads of water flowing out of the rotor holes but it just isn’t turning. It turns freely in my hands and spins fine when I flick it round.

    The water level in the bottom of the machine mid-cycle covers the salt dispenser and is just level with the top of the filter holder handle i.e a good 2-3 inches deep.

    Sorry for omitting model number it’s a Bosch SGS5312GB/12

    Would welcome any advice/thoughts and failing that if it’s a job for an engineer what sort of charge would be reasonable and can anyone recommend anyone near Staines/Woking area.

    Many thanks,

    Jonathan

    If there is plenty of water coming through, the fault must lie with the rotor. Blocked tip jets is the obvious one. Consider that the rotor is forced down by the water pressure, so it may be binding under load. New rotor and hub would be the solution.
