Have a GE dishwasher that will not work after cleaning lower filter and screens, all functions work but when press start it never does anything

I have spent all my career in the catering and food industry with dishwashers of all shapes and sizes.

The usual reason for this can be two fold.

First make sure that the bottom spray arm spins freely. For various reasons they can stick and that means the spray only hits one place. If you spin it, it should spin at least 2 revolutions. Even if it does....

Remove the bottom spray arm. The thing that makes it spin is the angled jets in either end. They will often block with debris, and the worst is lemon pips and cocktail sticks, even fluff. No one knows how fluff gets in there, but it does. At my last job at a VERY busy airport lounge putting literally hundreds of baskets through a day, the two filters had to be de-fluffed every day. The problem at home is that the fluff solidifies between uses. So look at those end two jets, poke with something and put water in from the jet end rinsing to the big hole in the centre. Put the plug in the sink so you can see what comes out. The turn the arm over and force a good jet of water into the big centre hole and it should show as a good jet at the ends. Then put the arm back and make sure it spins.

Your machine has a strange item called a 4 port diverter valve. This part concerns me a bit as it appears that it may be supposed to move or at least has to be in the correct orientation. Some items like this have a rubber flap that really does divert the flow. Once gain, some type of debris can ruin its function. It looks easy enough to remove.

Another trick is to whip the door open mid wash if it doesn't have a safety lock and see what the arm is doing and if it is spraying well.

I hope this is more use than our friend Umar Waheed! We are getting a lot of the AI Chat GPT4 Points Jockeys! Usually after 40 to 100 answers, they ask "How do I cash out my points" :>D

remove lower dish rack, see filter, 4 screws holding it down, remove screws and lift up - might be a secondary filter as well under that.

suck it all out with a wetvac

If you have cleaned the filter sump and you are sure the kitchen side of the drain hose is ok, then I suspect there is some problem in the separation circuit between the wash and drain pumps in the dishwasher.

See this diagram.
The turbidity sensor (item 321) could be faulty. This is supposed to check wash water quality and drain it out and bring in fresh water during wash cycle. The other possibility is the flapper valve (item 328) is not working properly. This valve is supposed to separate the drain and wash sides of the dishwasher.

First thing to do is buy a dishwasher cleaning kit (Finish brand if you can) from the supermarket and run empty dishwasher with it according to instructions on the kit. Use the hottest cycle available.

If this does not affect the quality of wash, then start checking the parts I mention above.

Hope this helps.

There are many probable causes of failure .

A dishwasher's water inlet valve is its most common part to fail. When your dishes are not being fully cleaned, quite often a faulty water inlet valve is to blame. Test your dishwasher's water inlet valve, and if it is no longer functioning as it should, you will have to replace it.

Water temperature is a key element in achieving clean dishes. A dishwasher's heating element is not designed to heat the water that enters it. Rather, the heating element is designed to maintain the heat of the water that enters the dishwasher. Its a good idea to run the hot water in your sink for a couple of minutes before you run the dishwasher. Just to make sure the water is nice and hot before it enters the dishwasher. If the water is unable to stay hot, it can adversely affect your dishwasher's cleaning ability.


There is a filter in your dishwasher. Its function is to keep large particles of food and foreign objects away from the pump. Many of the newly-manufactured dishwashers have self-cleaning filters, and routine cleaning isn't a concern. However, some other dishw ashers need to have the filter removed and cleaned regularly. If the filter or grate is clogged or blocked with debris, it may interfere with the normal functioning of your dishwasher

try c.l.r. to clean dishwasher check and clean lower and upper spray arms out, run no detergent you can also run vinegar in it as well about a cup full,let the machine start to run then stop dish washer for a few hours then restart see if this works for you use a short cycle.

Sir,

GE dishwashers will have a sumpentrance screen ( #4 ) that should beremoved and checked for any gookus, see 1 or 2 screws on the cover top, which isbehind the lower spray arm. Almost all ( some newer GE dishwashers have a separatedrain pump and motor - but for our purpose, we will talk about the mostcommon GE dishwashers ) GE dishwashers have a drainsolenoid ( #1 ) that can fail and stopthe draining. If the solenoid cannot pull in the silver plunger, the drain portwill not open to allow the motor and pump assembly to drain the water out. Thesolenoid can be ohmedwith an ohm meter for continuity, or tested to see if it is receiving 110-120 volts AC. Many GEdishwashers have a selfclean filter ( #3 ) inside at the back.The draining water must pass through a plunger in the self clean filter body.This can get clogged up, or the plunger may twist and distort and not allow thedraining water to get past. The filter can be removed from the inside and theplunger will twist out of the self cleaning body for testing/checking. Next obstaclefor the draining water in the backflush valve ( #2 ). This valve can twistor distort and block the water flow as well. The drain port will need to beaccessed to check this flapper valve, the drain port will untwist from the selfclean filter body. All hoses in-between the items mentioned above and the drainhose itself all the way to the house plumbing should be checked forrestrictions.

Good Luck

You have a washer control board problem or a burnt connector or both.

To clean this is little bit tricky.You have to open 2 screws on the oval screen filter which located close to the back wall inside the dishwasher.When you take the filter off you be able to reach inside this compartment by hand and clean it. If after this dishwasher still makes some noise than you call technician.
