    Hi, as in the title my Zanussi washer has been fine up to last week. it has developed a fault which threw up the E10 code.
    It is overfilling the drum by a huge amount and also the water is only coming in via the softener part of the dispenser drawer.
    I have changed the pressure switch and the twin inlet valves but there is no change, I would think the next thing is the electronic control board but I am very open to suggestions and advice please.
    Cheers
    Richard

    did you check the pressure chamber and pressure hose for blockages and damage ?

    Hi Dave, its certainly not blocked but no I haven’t checked that I will do that next, thank you.

    I couldn’t detect any damage to the hose or the pressure chamber although I wasn’t able to remove the chamber at this time.
    I can understand the water level being determined by the pressure switch but that wouldn’t explain why the water was only entering by the softener part of the drawer and not by the detergent side as well, I’m obviously not an engineer but that bit doesn’t seem to have a connection to the pressure switch unless of course there is some interaction that I haven’t considered.

    there are 2 valves

    one is wash valve and one pre wash valve

    to get the fabric conditioner they fire both valves

    so are both of your valves activated

    No, both valves are not, only the one that goes to the conditioner side of the draw, I can see the water flow through the top of the drawer lid, I changed the valves because of this which I thought would be the initial problem, so it seems to me that there isn’t just one issue.

    so its the pre wash valve

    if you cancel the programme does the valve stop letting in water or do you have to switch off machine ?

    The water stops if I cancel the program.

    also assume if you pause programme it stops too

    well the only things left are pressure sw problem or board

    you say you changed the pressure sw assume you have correct part as there are 12 machines with this model and they may use different parts

    check wiring connections and integrity of the pressure sw harness

    Cheers, all the wiring looks fine, the pressure switch was listed as that model but is slightly different although the plugs fit so I wasn’t too concerned about that. As you say not much left and I have located a board at a reasonable price, worth a go before I order a new machine !!

    be careful
    just because the board is listed for that model the fact there are 12 different variants of this machine might well mean the board have different software

    you wont because the pnc number is the commercial code of the machine and its on the label inside the door

    the model number these days can mean a number of machines in a range and the pnc number lets you find the exact machine to order correct parts

    all you can hope is the software is the same. you may find programmes differ
