    I am getting the code on my frontload washer F du, it is making a clicking sound the water starts to fill , then the code comes up..I am not able to find this code in my manual ..I am thinking that maybe...

    The DU in the display is an error code for the door lid not unlocking. This is an indication that the lid lock assembly has failed or the control board is unable to determine if the lid is unlocked. This usually indicates that the lid lock assembly will need to be replaced.

    Du error code on whirlpool cabrio

    that code is for the door unlock error. is it possible that you may have tried really hard to open the units lid when it was locked? if so the door lock may have been broken. if not, then try to unplug the unit for a few minutes and try a new cycle.
    if the code comes up again then you will have to call for free service as it has a 1 year warranty for parts and labor. yes even if you broke the lid lock!!! dont worry it happens when you get something new and are not sure how it works.

    Kenmore elite HE 3t - error code F dU and door is locked

    Just in case there is a pull string with a loop, all plastic under the latch, need to pull the toe panel off and reach up inside the right, unplugged of course until you feel the switch. a pull latch is below the switch incase this happens and hats off to all star/ a serial error or a faulty switch is most of what causes this to start.

    DU error code

    liz, DU could mean a couple of things. Something is preventing the lock bolt from retracting or the motor control cannot determine if the door lock is in a unlocked state. With the lid closed put it in a manual test mode by pressing any key except for power, start and stop. With all indicator lights off, press and hold for 3 seconds, release for 3 seconds, press and hold for 3 seconds, release for 3 seconds, press and hold for 3 seconds. If done correctly 88 should appear. While this 88 apears press the same key again within 5 seconds. You are now in the manual test mode. Now go over and press the second rinse or extra rinse key. This key will toggle between lock and unlock. See if the lock assy. is working. To exit the test, just unplug the washer for 60 seconds. If you don't have any luck with the test, you will have to do a bunch of tests on the lock mechanism to determine if in fact that is the problem. If it's under warranty, I would have the service company get into that. Catriver
