I have a maytag mdb9750aw dishwasher and it is

their is power to the dishwasher but the control panel does not light up and the machine will not start or run

Sounds like an internal timer malfunction.

Try to find your model # and serial number if not out of warranty before called.
It sounds as if your machine needs to be inspected by a service repair agent in your area. Maytag can lead you to an authorized local repair man.

I know this sounds silly but, check the level of the dishwasher, if the door does not shut exactly right with it level my lights wont work, I can move it slightly to the side and forward (leveling it up) and bingo I have power and lights.

Check for bones/glass/ceramic from chipped plates in the food chopper (for lack of a better term). You'll need to disassemble the entire lower arm unit.

remove all the screws on inside of the door .pull apart the inner plastic part of the door from outside panel and look at the door latch on the top of the door.probably it will be broken or door sws are bad.

Hi

Many times a complaint of noises ( grinding or scraping ) can be traced to a cracked impeller in many of the common motor and pump assemblies used today. Sometimes a poor washing complaint is common after this wash impeller has cracked. Remove power first before investigating.


The motor shaft has started to rust and swells out and this swelling cracks the upper impeller. Most times a new seal and impeller kit can cure this complaint but sanding and cleaning of motor shaft is required before replacing the new seals and impellers.

Please do rate the solution as FixYa and revert for further assistance.

Thanks

Check for foreign objects like glass or plastic at the grinder blades. Some dis assembly will be required. See appliancepartspros.com for diagram.

Sounds like a bearing in the pump is going. This would cause a leak be careful leak will get worst.
