I have a similar problem - sometimes the circulation pump runs, sometimes it doesn’t. It *seemed* to be that I could get it to run by switching cycles, until it didn’t. I tried tripping the latch before running (thank you for that suggestion, I never would have thought of that!), and that worked, but we’ll see after a few tries whether that is in fact the issue.
If so, what is the solution? Is it just a matter of bending the metal catch so it hits the latch mechanism better? replacing the latch? replacing the sensor? And is there a way to test if the latch sensor is failing to trigger?
I am pretty good with tools and repairs, but I like to know what I’m doing before I get in too deep. Any links to repair process would be greatly appreciated!
TIA
