My issues are very similar to the others posted here, (Love this site and all the knowledge I was able to glean!) After 4 years of daily use, now in the middle of a load all lights die (CSM is tripped according to the bottom control board light) resetting csm by going into error mode shows error code 815 and no other errors (only light lit after the 10 second test is the lock controls light, as it should be) Running a test on drain (while full of water), water, circulation, detergent, circulation, heated dry, AND vent mode revealed no problems (I have never used heated dry so that was a first test of that.) After resting the csm and going back into standard mode the light on the pcb reports normal circumstances (waiting for selection, 1 blink every 3 seconds.) Additionally there are no signs of any leaks that would explain a short circuit, and I've completely disconnected and reconnected the lower PCB connections.

I'm assuming as everyone else who's has had this problem has had to replace either / both of the PCBs in the machine that my first step is to replace the more easily accessible bottom control board, but I wanted to see if anyone has any ideas before I start changing parts...

Also, the pcb on my unit seems to be WD21X24900 (scanning the qr code on the pcb gives me the same part number that's written on the pcb of "GE265D1462G501MP00" which leads to a 900 pcb) mind you, the same site that gives me that link also says that it's "unsure" if that is the right pcb for my dishwasher, and says the x24901 IS the right one, so I'm willing to believe despite what pcb I currently have the x24901 is the one I want since everyone is reporting success with it and my model dishwasher but I would feel a bit better if someone told me I'm correct due to the discrepancy🤣 If it's any assistance see attached photo of QR code and part numbers on the lower PCB

Thanks for any help! Fingers are crossed that it's only the lower PCB...

One more thing to note (I can no longer edit the original post, sorry for the double post.) The longer it is unplugged it will run longer (up to 15 minutes?) or if the PCB is allowed to hang freely (screws detached kick panel open, more airflow) it runs even longer before faulting (When I tried it that way I got more than 20 minutes out of it basically right up until I decided it wasn't going to stop and started to pack up :lol: (This is why I think it is an issue with the lower PCB, but I also want it to be the lower one, so checking with you all before spending money...)

Hi, Yes, the problem is the lower machine control board.

--->Here's the machine control board for your model you can order: WD21X24901 Machine Control

Excellent, Thanks for putting my fears to rest the part is ordered and my WD21X24900 will be upgraded to a 901 next week 🤞

Glad to help, let us know how it goes.

After 2 completed loads in the dishwasher I can confirm that the above referenced part worked a treat with no additional connections needed. $91 well spent (express shipping, woot!) Problem solved, here's hoping the new PCB lasts for another 4+ years

Excellent, glad to hear the new machine control board fixed it.

Thanks for the update!
