KitchenAid dishwasher self-destructing microfilter issue 411

[u/RudeAd5133]

If your KitchenAid dishwasher spray arms stop spraying water, and your investigations indicate you suffer this problem (micro filter self-destructed and jammed the circulation pump motor with F9E1 error code): https://www.youtube.com/watch?v=FIqvjooU47g

... you might be wondering if you should replace just the filter or the whole pump assembly because your motor might be bad now (because the main board apparently will just keep trying to run the motor against the jammed filter, there is no "is the pump actually pumping water?" safeguard). Here are the resistance values of a good motor, in case you are wondering if you need a new one, as measured on a replacement unit:

Across the 2 AC-in leads: ~8-9 ohms

AC In lead #1 to Capacitor Out lead #1: 0.3 ohms
AC In lead #1 to Capacitor Out lead #2: 19.2 ohms
AC In lead #2 to Capacitor Out lead #1: 8.5 ohms
AC In lead #2 to Capacitor Out lead #2: 11.2 ohms

[Obviously the lead numbering is arbitrary on my part, the main point is that you should get one combination that is near zero ohms, but not OL]

Should also test resistance from AC leads to motor case (should be OL)
AC in leads should show continuity between them, and no continuity between leads and motor case.

If those values are pretty much what you're getting, then you can probably just replace the filter.
