Hello,

We opened our dishwasher and it was super hot inside to the point it melted some things. When I tried to start it again water was flowing and spraying for maybe 30 seconds then the water stopped and didn't seem to flow anymore. We rest the breaker with no change, I changed the water inlet valve with no change. I took thr flood switch out and test pin 3 and 5 with my ohm meter and it read about 11k so I think that means it's good. I have no idea what else to test. I thought for sure it would be the water inlet or flood switch.

Sounds like your wash(circulation) motor is failing.

Here's the service manual for your model: https://drive.google.com/file/d/1Fefp5_Ibg86DtJhjwzL5kPqGBSicyP1v/view?usp=sharing Look on Page 77 of the service manual I posted above and it has a Circulation Diagnostics troubleshooting flowchart there that you will need to follow to see if your wash motor is bad.

Here's the updated wash pump kit that includes all the electrical wiring you can order, IF your wash motor is bad:

Let us know what you find.

Thanks Jake. I will test it tonight and post back. Can you explain to me why you think its the wash (circulation) motor? I'm just curious b/c I originally crossed that off my list b/c when I started the dishwasher it sprays water for maybe 30 seconds then just stops. I assumed that meant the circulation pump was working but you mentioned may be failing so is it possible that its nto dead and on its way out so after a short time of running it shuts itself down? More then anything I was just curious on your logic for my own knowledge. I will run the diag later not that I have the service manual and let you know. The manual will help a ton:)

Thanks again.

Quick update: I ran out at lunch and started a light cycle just to see what it did again and make sure I'm providing the right information. When I start the load water runs in and I can hear it spray around inside for about 2 minutes. Then it just sits there and it doesn't sound like its doing anything for a while. I opened it up and there was water in the bottom but not enough to cover the heating element. I'm unsure if that is a normal amount of water for the light cycle or not I guess it may be. Based on past behavior I uspect it will sit as it is now until its time to drain and it will drain fine. As I write this it sounds like its filling and draining and not washing so your suggestion of the water motor is making more sense to me. At any rate I will still run the diag later and report back.

Ok Jake I entered service mode and was able to successfully test that the unit filled and drained so I filled it again (Im not sure if I had too but I wasn't sure if the circulation test would run if not) and then I started the circulation test and the spray arms didn't move at all. I assume this means the wash pump is most likely bad.

I wasn't 100% sure on how to go to the main control board to check 120vac at connector J702. Do you think I should do that before I order the part? If so what am I looking for there the flow chart just says "check for 120vac at connector J702 pin 2 YB - pin 3CR (wash motorcycles 30s off 1 s on 30 s off 8s)" Am I just checking that there is power when holding my leads on pin 2 and 3? Then the next step if that is ok says check wire harness if tan/red is open between the control and motor replace motor and harness. In that case am i just testing the motor by disconnecting it from the board and testing for continuity?

THanks

Yes, the wash(circulation) motor should run a long time and not stop like that.

I opened it up and there was water in the bottom but not enough to cover the heating element
The water level is not suppose to cover the heating element on these models, it should cover the bottom of the tub, then the wash(circulation) motor is suppose to spray water OVER the heating element, thus it heats the water higher.

I entered service mode and was able to successfully test that the unit filled and drained so I filled it again (Im not sure if I had too but I wasn't sure if the circulation test would run if not) and then I started the circulation test and the spray arms didn't move at all.

Yes, I would agree.

Do you think I should do that before I order the part?

Yes, that is correct.

I wasn't 100% sure on how to go to the main control board to check 120vac at connector J702.
Here's the chart that shows you how:

Thanks for all of the help Jake. I got the new circulation pump kit in today and intsalled it and evertything works good.

Last night I opened up the main board and tested the 120vac but that diagram above has one thing wrong for my model and it was throwing me off for a bit. I eventualy looked up the schemtic in the back of the doc you sent me for my model and its correct. It shows J703 as the connector for the circulation pump and J702 is actualy the heater. Once I figured that out my tests started to make more sense. I almost thought the board was bad b/c I couldn't get 120vac on J702 when the circ pump was on but I randomly checked J703 and I did eventhough the onlything I was running was the circ pump so that made me check the schematics and sure enough J703 was the circulation pump. At any rate the manual you sent was so much help. It made this much easier.

Thanks again!!!

Excellent, glad to hear the new wash(circulation) pump kit fixed it.(y)

Yes, sorry about that, there is a misprint, it should be connector J703 not J702.

Thanks for the update!
