2 Why does my dishwasher work sometimes but not others?
I have a Whirlpool dishwasher that is about 5 years old. Lately, it has been not working more often than it works. What happens is I open it after the cycle to find that the tablet is undissolved on the bottom and the arm has not moved. I ran diagnostics, which sometimes gives the error code 4-3 and sometimes 1-2.
I don’t think it’s the circulation pump because, if it was, why would it work sometimes? If I reset it by cycling the electricity, that sometimes makes it work—but not always.
Any clue what could be going on here?

Hi David,
Can you open up your dishwasher and retrieve the model number for us? Whirlpool makes a LOT of dishwashers and we can't be sure of getting you accurate information without knowing exactly which one you have.

Sure, it’s WDF520PADM.

Do you have hard water? Lime buildup could be clogging the arm and the spray holes.
Also check if the timer is set.

I've deleted the request for the serial number of your washer; I have yet to see a repair request where that specific amount of detail was needed, and it can potentially have personally identifiable information, where the model number does not.

If line buildup were causing clogs, would it still work part of the time? Last night, everything worked great. We’ll see how it is today.
