once the heavy, normal, or light button(s) are pushed then the steam & heated dry buttons light and unit locks up and only the heavy, normal & light buttons will work. I've already disconnected the ribbon wire from controller and then powered unit back up & the drain motor did come on for 2 minutes. I don't know what else to do until I find a repair manual for it. any suggestions?

Here are your parts Parts for Maytag MDB7709AWW2 Dishwasher - AppliancePartsPros.comThe tech sheet is too large to upload on this site so I has to use another site, see below Download MDB7709.pdfUn-click the " use our download manager" as this may install software on your computer t6hat you do not want and then download it using the gray button. Does sound like a control board problem. You could check the control panel/keyboard keys with a meter (see the tech sheet). If it checks out OK then I would replace the control board. You may also want to try the following. 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. Use electronics contact cleaner or isopropyl alcohol. 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. |

I noticed my heat dry key quit working last week..stayed on. Then last night I tried to turn my DW on and nothing. The start button is dead..get a few buttons to light up but no start. Could this be a bad touch pad control or should I go with the control board?
I did unplug the control panel from the board and plugged back in ...drain pump worked for about a minute or so...then everything shut down again.
Thanks
