The problem is hard water. There is a new product out called the dishwasher filtration system. It filters the water before it enters your dishwasher. It works amazing and has a money back guarantee. You will love the way your dishes look after the first load. It is also very affordable (like 70 bucks). Go to www.dishwasherfilter.com to find out more info.

Hi,
Sounds like either the control board or the keypad.Try removing power from the unit to see if it will reset.
Now try running the diagnostics…

RIBBON CABLE CLEANING
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.
If all the above does nothing, remove and check the keypad with a meter, if it measures OK, I would suggest replacing the control board.
Thanks for contacting fixya.com

You are missing the last digit of the model number. The control overlay is bad. The part number for the white overlay 99003530. This is very common on this model. If you have a different color you will have to look it with the last digit which is the color indicator.

Hi

Thanks for using FixYa. Dishwasher not draining properly or not draining at all issues can arise due to different reasons. Usually, these issues are related to kinked hoses, knocked out disposer unit (if connected with the dishwasher drain hose) & clogged drain pump & filter.

Also note that dishwashers do not drain completely after a finished cycle and this is normal. Dishwashers are designed to leave some water in the unit to ensure that the heating element doesn’t overheat. If you suddenly begin to experience a large amount of water being retained in your dishwasher, you have a problem. Some of the most common reasons include that the drain hose isn’t working properly, the drain pump isn’t working correctly, or possibly there is a plumbing problem in your home’s drain lines.



First check whether the drain is not clogged or blocked and the line is not kinked. Check all the hoses for blockages & also clean the air gap. Has the disposer been replaced recently? If so, chances are the knockout is still in place. Simply remove the drain hose from the disposer, and knock out the plug. If the disposer has not been replaced, try removing the drain hose from the disposer and use a wet-dry vacuum (prepared for water, of course) to **** any water (and hopefully anything else) from the drain line. Then reconnect the hose, and test the unit. If you have checked the air gap and the drain hose and can’t locate the problem, then it is an issue with the drain pump of the dishwasher.

Please do rate the solution and revert for further assistance.

Hi,

Follow the steps :-

Power from the house Is there power getting to the dishwasher? This can be difficult to test, because dishwashers are usually wired directly to an electrical circuit, rather than plugged into the wall. But at least check for a blown fuse or a tripped circuit breaker.

Door switch The door switch is important because, if it's defective, the dishwasher won't work at all. To reach it, you need to remove the control panel cover, or sometimes the interior liner of the door. If it's defective, you need to completely replace it.

Wiring Often the main wiring connection from the house, at the dishwasher, burns and breaks the connection. If that's the problem, the wires must be repaired/replaced as necessary. If that's not the problem, check the wiring to the door switch, the wiring between the door and the lower part of the dishwasher, and the wiring to the timer. Repair any broken, burned, brittle, or defective wiring, using the proper appliance-grade wire and connectors.

Timer or selector switch Although it's uncommon, the timer or the selector switch may be defective. If so, you need to replace the defective part, because neither of these can be repaired.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

i would say it's a serious internal problem ...not a simple fix ...call for service

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

Hello cljjtm,
You will need to clean the wash arm and unclog the spray holes.. use white vinegar to break down the soap deposit and a sharp metal tool such as an awl to free these holes up from any build up.. white vinegar may be applied while unclogging the openings..
Then, once the spray arm holes are freed of deposits..Start with an empty dishwasher.. and then start a wash on the hottest available setting and then after a few minutes of it cycling.. pause it and add a cup or two of white vinegar to the wash ( the white vinegar should break down any soap residue and allow it to be rinsed away)..once complete.. use about 1/3 less detergent than you have been. See if that gets your DW back in working order.. Hope that helps..
Regards,
Rick

Check the point where your power is making its first contact to dishwasher.Usually on right side under the unit youll see the box .First remove the bottom panel.Than remove the cover plate on the power box.In side htis box youll have to CAREFULLY make your tests.

run a cycle thru with no dishes and 2 cups of vingar this will flush out the unit then run a normal load should be ok let me know THERE also is a product called dishwasher magic you can run that thru as well but the vingar is cheaper

Make sure your heater is operating.Make sure your using rinse aid.

is vent cloged if not you got something loose

I suspect something hard like a fragment of chicken bone or a citrus seed is at the inlet to the drain pump (my favorite was a plastic pull strip from a frozen juice concentrate can - that was LOUD). Many dishwashers have a chopper similar to that in a garbage disposal right before the pump inlet, but some things like bone won't go through it. It could be something light enough to float and only hits the pump when the water level drops. You may have to remove the pump cover in the bottom of the dishwasher to find it. This would be a good time to clean any garbage out of the lower spray arm and check the spray arm bushing for excess wear.
