All selection LEDs will light when indicated except the "Normal Wash". But no matter which cycle is selected, none will start dishwasher. I had repairman verify door latch & power good. He says it's either the control panel or control board. Any way to know which? Unit is less than 2yrs old.

Here are your parts Replacement parts for MAYTAG MDBH945AWB3 UNDERCOUNTER DISHWASHER | AppliancePartsPros.comSee the attachment for the tech sheet. And finally here is a manual for this series of units 16021814 Maytag Jetclean II Dishwashers Service Manual - ApplianceDigest.comYou have to join the site to download the manual but it is free and this is a very good site for manuals and other info for the appliance repair DIYer. Have you tried unplugging/removing power from the unit for 5 minutes to see if the board will reset? You could try the diagnostics to see if anything pops up. If neither of the above helps then the usual way to trouble shoot is to check the control panel keys with a meter (see the tech sheet), then if it fails replace it. If it passes then replace the control board. Still a bit of a crap shoot but your odds are better. You may 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. 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. |

When I pulled the control panel to clean the ribbon strip connections, I noticed several of them were blackened. Pretty sure that's my trouble. I will order the part and let you know. Thanks again.
