    Default Whirlpool Duet - F/09 code

    Model Number: GHW9150PW2
    Brand: Whirlpool
    Age: 6-10 years

    Jake,

    I am having issues with my Whirlpool Duet Washer. (Previously you helped me fix our dryer - thank you again for that!)

    The washer started by giving us a F09 code, though my daughters saw they also saw F/11 but I haven't been able to duplicate that yet. I started a Rinse/Spin cycle, and it appeared to pump water out and was spinning some. I used the Cancel button to stop the cycle, and it stopped. A couple of moments later, it started up again, so I've just kept it unplugged. Using the repair manual I found on the forum, I began working through the list of things to check as a result of F09 codes.

    - The drain hose is not kinked or clogged.
    - The wire harness to the CCU and Pressure Switch seems to be good.
    - Got down to the drain pump and cleaned it out. (Hmmm, broken pencil and other small items made it down there!) How do I check to see if that's working?
    - How do I check to see if the pressure switch is working?

    Given the funky behavior of the control panel and the machine's desire to start on it's own, might this be a CCU issue?

    What else should I do?

    Thanks!
    Marianne

    Ok Marianne,

    Take the lower access panel off below your door and you will see a tech. data sheet on the inside of your cabinet panel, run the diagnostics test and see what error code you get.

    F9 is a water pump problem, either clogged pump, or pump malfunctioning. The diagnostics test will test the water pump to see if that still working fine now.

    Here's the water pump for your model, its on sale here:

    The washer must be empty and the control must be in the OFF state before pressing the touch-pad sequence to start the test. Close the door. Push CONTROL/ON (if present on this model). Select the DRAIN/SPIN cycle. Select NO SPIN by pressing the SPIN SPEED touch-pad. Push PREWASH OPTION four times within five seconds. If PREWASH OPTION is not present on this model, press RINSE HOLD four times within five seconds. C:00 will light up on the display. If the Starting procedure fails, push the PAUSE/CANCEL touch-pad, then repeat the starting procedure.

    In order to advance to the next step of the test procedure, push PREWASH OPTION touch-pad two times. If PREWASH OPTION is not present on this model, press RINSE HOLD two times.

    Jeff and I posted the exact same thing at the exact same time in another thread. Now Jake and I did the same thing. I can only conclude great minds think alike!

    Alright, we reassembled the machine and entered the diagnostics. I don't have a PREWASH or RINSE HOLD but the EXTRA RINSE works as a substitute. On multiple attempts to get the full diagnostic test, I've only gotten it to go once. On the one it ran through, it was at CO5 or CO6 that it popped up the F09. (On the other attempts, it didn't get past C00 before popping up the F9.)

    Also, another couple of questions:
    - is it "normal" for the machine, once the F09 code has been cancelled and the machine shuts off, for the machine to start back up on its own a couple of minutes later?
    - the one time it start running through the diagnostics, on C01, I didn't get the sense that it was actually filling with water.

    Thank you, gentlemen - I'm so eager to get this bugger running again, and I really appreciate your help!

    DUET GHW9150 F09 ERROR
    If the overflow contact on the pressure switch is closed for more than 60 seconds, an Overflow Condition will occur. In an overflow condition, the door remains locked and the drain pump runs constantly, even if PAUSE/CANCEL is pressed twice and the display is cleared. Turn off hot and cold water faucets and unplug the unit before servicing. Check the drain hose and make sure it is not plugged or kinked. Unplug washer or disconnect power.. Check wire harness connections to the drain pump, pressure switch, and Central Control Unit (CCU). Check/clean drain pump filter for foreign objects. Check for drain pump failure. Check the inlet valve for proper shut off. Check the pressure switch for proper operation. Remove the pressure switch hose and blow through it to clear it.

    I've done all but the items quoted above. How do you check for drain pump failure? (Yesterday it seemed to pump out the remaining water.) How do you check the inlet valve for proper shut off? How do you check the pressure switch for proper operation?

    I'm great at following instructions and not afraid to get dirty or technical, but I haven't found anything to help me with these items.

    First clean out the pump. Continuity checks can be made on various components of the washer from the connectors on the Central Control Unit. Before performing any of these tests, disconnect the washer from the wall outlet. In addition, disconnect the wiring harness connector from the Central Control Unit before making any continuity tests.

    Thanks; the drain pump was cleared out yesterday (pencil, hair rubber band, arts&crafts pompom, etc.....).

    On to the testing:
    - drain pump: good
    - pressure sensor: empty and overflow good; suds detect and L1 nothing
    - inlet valves: hot & cold good

    So, it looks like it's the pressure sensor!

    All of you are the absolute best - thank you for your help and the fun of learning yet a little more about appliance repair!

    OK, before you order the pressure switch, blow though the hose and make sure it's clear.
