The spray arms in Whirlpool WDT780 dishwasher are plugged with food. Filter isn't catching debris. Two questions: how do you get food out of the arms? Second, why isn't the filter catching the debris.

SOURCE: Lower arm spinning slow/intermittent

running with the door open indicates another fault that could be dangerous unless you have bridged the catch for testing only, water should flow fast and forceful at all times that it circulates, through both spray arms at once, you have to look for blockages in the system, is the waste outlet pipe high enough, this allows the machine to fill adequately so it doesn't pump intermittently, i doubt very much this is an electrical problem hope i have helped a little

There is a plastic clip that holds the spray arm to the inlet line. This clip is in the center and has to be sqeazed together to release the arm.

Both upper and lower spray arms become clogged by different objects like paper, plastic, stems from fruits, etc... These are particles that cannot br dissolved be the detergents.

You may have stripped the threads on the spray arm or spray arm support. I believe the threads are reverse-threaded and since they are plastic, can easily be stripped if turned in the wrong direction. This has happened to me before. The solution is to replace the lower wash arm and spray arm support. You can find the parts at repairclinic.com. Just type in you model number and look for item numbers 830883 (spray arm support) and 9040141 (lower wash arm). You may also want to check out searspartsdirect.com as well. The parts will be located under the "Lower Washarm and Strainer Parts" section. The two sites do offer comparable pricing. Post back if you need further assistance. I hope this helps you.

The quality/quantity of responses you get here on FixYa can greatly vary for WHEN you place your question.

There are a handfull of "experts" who use fixya that simply have a generic cut and paste answer for every question asked on FixYa.

"Final Answer" is one.

Many have little to no english skills, and resort to cutting and pasting the same answer to every question.

I apologize for their ignorance and im sure your post will soon be answered by knowledgeable QUALIFIED personnel.

Real answers are not automated here - I assure you. Give it a little time for our experts in the US to wake up and get coffee into their system.

We are not employed by FixYa - sitting in a little cubicle waiting to answer questions. Most of FixYa experts do this in their spare time between real service calls.

Now that's out of my system I can try to help troubleshoot your problem.

Bosch dishwashers use a water system called FLOW CONTROL... which utilizes a valving system to control which arm gets water during the cycles.

Most washers see water at both arms all the time. Yours is controled with a PLC and uses information gathered from onboard sensors to tell the valves to open or close.

Your Lower sprayarm valve is faulty, or the controller board is bad.

Since we do not know your mechanical/troubleshooting skillset - all we can do is offer advice and try and help you if you feel this is a problem you would rather attempt to tackle yourself.

I have searched BOSCH website and could not find your model washer in their documentation. Please double check that it is SHV55M03GB/40 that you posted.
