Dishwasher is out of warranty. It runs, but the touch pad will not let me delay or change cycles... It is stuck in one mode..... only two green lights work on the display... I bought the electronic circuit board but I think I need something else?:D

Here is the parts breakdown Replacement parts for mdb7751aws1 models | AppliancePartsPros.comHere is the tech sheet http://www.servicematters.com/maytag_library/docs/16026394.pdfThe usual way to troubleshoot these units is: Unplug/remove power from the unit for 10 minutes or so to see if the control board will reset. If this does nothing. Try running diagnostics to see if it will give you a clue as to what is going on. If this brings no joy Unplug the unit and check the keypad with a meter to make sure all keys are opening and closing. If it checks out OK replace the control board. Still a bit of a crap shoot but your odds are better. If it has problems replace the keypad. You may also want to try the below. Connector Cleaning / Checking Unplug the unit Open it up Remove the ribbon cable from the keypad to the control board at the control board. Clean the edge connector. If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive. Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here. Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates. Reconnect everything and give it a try. |
