Whirlpool wdf520padw5 dishwasher not spraying

Yes this right here was my problem. Mine did the same thing. Same model also . The little lever arm had came loose. I reattached it and it’s working great. https://www.youtube.com/watch?v=YNu9gWv2...

Wash Pump Worn Bushings

There are many possible causes to this problem. If you are getting 120 volts at the pump motor a likely cause is worn motor bushings which allow the rotor to lock up on the stator. If this is the case the easy solution is to replace the pump assembly. If you’re handy you could machine up some replacement bushings and give that a try.

It was actually the float switch that it located just below the door. It has a little lever that rocks up and down and it came loose and I just put it back together and no trouble since. This is what the switch looks like. Also since I fixed this the washer washes like its brand new again lol Here is how to fix it. https://www.youtube.com/watch?v=YNu9gWv2...

I had the same problem. Removed the pump motor, cleaned it up and put it back. It works like new now. There as nothing in the motor but maybe it was stuck. Little sticky inside. Maybe the connection was not good? I turned off the switch and it took over 30 minutes to fix. When the breaker was turned on and I started the 1-hour cycle, the LED display showed that the dishwasher was resetting. Anyway, it sounds like it is washing even better than before it broke. I should add that it was the Circulation Pump part# W11032770

Controller board is not functioning properly and needs replacement. All commands come from there so some component is d a maged.

I replaced the inlet valve, checked and bypasses the overflow relay and replaced the pump motor but there is still no spray during the wash and rinse cycles.

Still don't know what's wrong.

I found this somewhere else. We couldn't get any other fix to work so we decided to try it and see what happened. It worked

We did not do the “making parts" like he does at the end. We just cleaned it out. It surprisingly had some weird stuff in it. It works better than it ever did. We may have to replace it one day, but it's been working for 6 months so far and we saved $120.00.

The impellers tend to come off of the circulation pump do to stripped/deteriorated brass threads in the impeller.

I had the same problem, went through all the online discovery Youtubes and blogs, replaced controller, water inlet valve, plunged the kitchen sink, cleaned all filters, and still there was no wash. Here is my solution: IF your dishwasher is 4 or more years old with the above symptoms of this problem where it fills and drains and seems to go through the timing, but the washer arm(s) are in the same position as when you started, then it is likely the circulation pump. I got one from Amazon for $99 (plus $15 for extended warranty), followed a wonderful YouTube that was on that Amazon pump sales page, and the dishwasher cleans like new!

I took advantage and also cleaned behind all the manifold tubing that carry water to the arms (they were YUCK behind them), and am a very happy now.
