Intermittent Circulation Pump Activity
I have a whirlpool du1100xtpt9 whose circulation pump had been deteriorating for years, it was obviously failing and was getting louder and louder until it finally died. I ordered and replaced the pump (WPW10757217) and it worked fine for about half a dozen loads. Then, when starting a cycle, the machine would fill with water, but the circulation pump would only make a faint humming sound without circulating any water. I was informed that its likely a blockage somewhere, but I checked both the interior drain and reseated the pump to check the connection there too. No blockage detected. I decided to run a test cycle to see what would happen and it ran perfectly fine. Once. Since then I’ve had the same results as before… washer fills with water, pump emits a faint hum, but does not circulate water.
Did you ever figure out the issue I’m having the same problem after installing the new pump and motor as well
Sorry, no. I ended up getting a used oem pump off ebay and replaced the new production headache that was producing this issue. Still going strong
