Question about Dishwashers

1 Answer

I have a Maytag QuietSeries 300 dishwasher. My original problem was with the control panel lights not coming on. Another repair website recommended replacing the circuit board. We replaced the board, but it did not solve the problem & the dishwasher would not work. Replaced the control panel. Lights come on, but when the start button is pushed "21" flashes on the time display. What do I do?

    I followed the procedure you described in your solution. The plastic retainer clip was never removed from the circuit board. I rechecked my connection from the conductor strip to the circuit board. The conductor strip is fully inserted, the retainer clip fully pushed back. I still receive the same error code: 21. Any other solutions?

    I followed the link you gave & read through the posts @ that site. In your link it refers to replacing the membrane, with a link for a control panel. I've already replaced the control panel. Any other help you can give me?

    It is a DWL7075DWW or ...DBBB or ...MBSS. The control panel buttons will not light up or work.

    Ok here is a solution to your problem.

    There is a particular procedure to plugging the conductor strip (coming
    from the panel) into the circuit board. The correct method is to place
    the plastic retainer clip on the circuit board connector first (if you
    have removed it). Pull the retainer out slightly and insert the flat
    conductor strip into it.

    Then push the retainer in to lock the conductor strip in place.

    PS. The mistake that you might have made was to remove the plastic retainer clip and
    place it on the conductor. Then push the conductor strip into the
    connector and slid the retainer down the conductor strip and onto the
    connector. THIS DOES NOT GIVE A TIGHT CONNECTION and if the machine
    works at all it is only because of luck.

Control Panel Problem on a Maytag DW MDBTT79AWW

I had this same problem, ordered the replacement control panel from whirlpool. The new panel worked for two weeks, then stopped working again. OUCH!
The replacement part costs $264.34 and has no warranty if you do it yourself.
I think I am now going shopping for something other than a Whirlpool or Maytag machine. They have terrible customer service.

Check the Lid switch. Most top load machines will not spin unless the lid is down and this is determined by the lid switch.
