I’ve read the other threads and watched videos on YouTube, but I’m still stuck. We have a six year old WDT720PADM2 that has been NOTHING but problems for the past six months.
Initially, wash cycle wasn’t running well. Food stuck on plates, and soap not dissolved. After chasing my tail (and diagnostic codes), here is what I found:
1. If left to it’s own devices, the water fills and drains. Heat works fine. Spray pump doesn’t work.
2. Service mode returns codes, of which there’s been many. I replaced the OWI sensor and the control board, based on the service manual. We always run the hot water at the kitchen sink before starting. No improvement.
3. The service mode gets the spraying to work well. Like new, actually. Running this mode usually gets the spray pump working again for the next 1-2 cycles.
4. No blockages anywhere…strainer, drain, spray arms. I haven’t taken anything apart beyond what I mentioned on account of service mode getting the spraying to work.
So I’ve read a lot about these pumps dying, but for the life of me, I don’t understand how a bad pump with a worn bushing will work consistently during the service mode and then for another 1-2 wash cycles. Seems like that should just never work. I figured this was caused by a bad controller, and that was supported by a code that seemed to verify the fault. But again, the new computer didn’t change a thing.
Any help is much appreciated! I’d hate to throw this in the landfill, but that’s the next stop if I can’t figure this out!
