    What a great forum I’m so glad I found it.
    I have a problem with a Fisher and Paykel GW709AU excellence model Machine 1999 and was wondering if I could please get some help.
    As posted by others my machine will not go into the spin cycle or start a new wash. ie will not fill with water.
    I get a constant beep every 1 second after an attempt to resume the prior cycle fails.
    Could someone please email me the diagnostic codes / procedures so I can provide further information on the problem I am having. my email address is

    marktc44@hotmail.com

    Thanks in advance

    Have emailed your the diagnostics.

    Re: Fischer and Paykel GW709AU

    Thank you for an outstanding response time.

    The fault code as per the instuctions I kindly received is 00110010
    That is if I did everything correctly.
    Under diagnostics the pump worked but hot and cold water testing failed.

    Thank you again

    😀

    Hot water valve fault, Mark. Check harness for continuity, valves should read 64 ohms. Possibly board fault.

    Got your email.. Thanks Again

    Hot water valve did not register. !
    Cold water had 75 Ohms.

    I was not sure what you meant by “Check harness for continuity” 🙄

    Is it possible I have more than a hotwater valve problem considering the cold water will not work in diagnostic mode?

    Thanks again

    Just to add to the confusion I pulled the hot water valve out, examined it, cleared the water from it, and reinstalled.

    On retesting it has come to life and shows 65 Ohms.

    The error remains the same under diagnostics as 50.

    Hope this might narrow the problem down.

    Thanks

    You should test the the valves with the washing machine assembled with the sequence of buttons pressed as on the page 37 which I sent you.
    If they only dribble a liitle water in then they are OK electrically but no good hydraulically.
    If no water enters then to recheck electrical continuity (circuit), there are little copper pads on the coil to enable this test without fiddling around where the plug goes.
    Do this test with the power and valve leads unplugged.
    As long as the valves register 64 ohms +/- 20{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} then you have no electrical problem with them.
    These low voltage coils on the valves are virtually bullet proof and would be only the second one I know to have failed.
    Removing water from a valve may reset that valve to work again hydraulically but this will not last.
    A voltage test with everything plugged in as per page 37 will give 24volts
    You must only do this test if qualified as lethal voltages (380 volts) are present when the cover is removed.
    These test will confirm continuity (circuit) of both the coil and the wiring (harness)
    If no ohms or water, replace the valve
    If no 24volts replace the Module

    Thanks Alexa

    Both Hot and cold test ok for Ohms as per your post
    No water is released under any condition.
    I’m getting no volts from the cold valve lead and around 20 volts from the hot valve lead.

    So am I correct in concluding that the motor control module needs to be replaced ?

    Thanks

    Yes, replace module.
    Phone F&P spares on 1300 650 590
    Approx $200
    I’d order valves at the same time as the diaphrams are notoriously for failing.
    Approx $50 each
    Hot and cold valves theoretically cannot be transposed as the cold valve is a proportional valve.

    Same problem, same codes.
    i’ll check the Resistance and Voltage in the morning and let you know the outcome.

    Re: Fischer and Paykel GW709AU

    Hi again,
    Checked it this morning and the Cold Valve is open circuit.
    When i check the voltages there is no power at all to either coil.
    Machine starts and starts to move the drum, then stops then starts, then stops. at no time on a normal cycle can i get the 24V at the soleniod coils for the Hot or cold water.
    Then after some short time 5 mins? it gives the 00110010 error and in diag gives the same error.
    Please Help.
    ohh what should the PN be for the Cold Solenoid.
    to change them is the easiest way solder it back on the board or splice the wires??
    Thank you all once again.

    Steve
