    Question F2 Fault Code DD602 DD603

    What needs to be done for F-2 error code on model # D-602. Immediately after powering on within two minutes I get F-2 code on bottom one and it stops.

    F2 is "motor not sensed to be rotating"
    Possible causes are frozen or stuck motor rotor, failure of the RPS sensor or failed stator assembly.

    The most common cause is a stuck motor rotor.
    The motor rotor for your model looks like this:



    Check the motor rotor and make sure it can spin freely, and that both the upper and lower impellers are securely attached to the shaft of the motor rotor. The motor rotor can be removed with no tools in about one minute.
    Take out the base rack, lift off the wash arm, then rotate the collar on the large filter plate counter-clockwise to the stops, and lift off the filter plate. Now rotate the collar on the motor rotor counter-clockwise to the stops, and the assembly should lift out. if the motor rotor does not want to come out, you have a rotor that has possibly fused itself to the pump base. This would require replacement of the base as well as the rotor.

    On double-drawer models, an easy test is to simply take the motor rotor from the working drawer and swap it into the drawer with the F2. If the problem goes away, replace the motor rotor.

    On model DD602, the part number is 525884P and you can order them here:

    If you require a new base, we sell a "complete pump assembly" which includes a motor rotor, base and RPS sensor. You can order here:
