My GE model GDF620HMJ0ES dishwasher middle arm doesn't spin

SOURCE: Upper arm does not spin

Hi,
OK, the arm is jet-propelled, so it will spin if it is free to rotate and has water squirting down into it. If it >is< free to rotate, then either the water isn't squirting, or it is missing the target. On my machine - different brand - the guide cone came loose when I dismantled the upper bar assembly and it hadn't gone back correctly aligned, so the water missed the hole.

I'd check that first. D.

I had the same problem and found two things which were causing it
-The O-ring was missing off of the tube connection on the back of the dryer that inserts into the sprayer tube. I found a size 11 O-Ring at Home Depot and it worked
-The openings on the underside of the spray arm are what propels the sprayer to spin. I found small pieces of plastic debris in the openings and cleaned them out.

Now the middle arm spins like it should.

I'm the one that reported the same problem in November as "Guest". I fixed mine finally. I removed the middle arm again and noticed that the holes that spray a jet ot water causing the arm to turn aren't the ones on top. On the bottom of the arm there's a small hole at each end. I looked and one of the holes had a small piece of crud in it. I had to use the tip of an ice pick to dislodge it back into the arm. I then ran water into the arm several times hoping to get the item completely removed. I never did see anything come out but I then ran water through the arm holding it so the water could run out one end. The piece didn't show up in the hole again so I tried washing it to the other end. It still didn't show up so I guess it must have washed out the first time. It's been 3 or 4 weeks now and the arm is still functioning perfectly. Hard to believe that one little piece of trash can cause so much irritation. Good luck on this being the problem for others.

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.
