    Good afternoon everyone,

    I’ve visited the above dishwasher earlier today, and replaced the impellor jug/flow sensor, which I realise is a fairly common cause of the above symptoms.

    However, fault remains.

    On a new cycle, the dishwasher drains and fills normally, then the check water light illuminates, and the unit drains and fills continuously.

    The d/w drains perfectly, the internal drain hose from the pump is clear, as is the matrix, and I’m now wondering if the board is faulty?

    Please could someone let me know if I should be checking/testing other areas?!

    have had wires from impellor jug eaten by mice before today so check wires back to board and the connection to the board

    Wiring to and from flow sensor to board good, so suspect board sending and receiving incorrect “messages.”

    Has anyone found the board to be at fault for this problem, as customer would like d/w repairing?

    Have had a look at the info’ Dave, but will probably have to admit defeat on this problem, as I renewed the board earlier today and the fault remains.

    I just don’t know why, and feel the need to cut my losses….

    Thanks again for your help.
