Notices different noise when in WASH cycle
Followed video for diagnostic mode testing
Test 7 for vario bounces between 1LO and C63 codes.
Put iphone in waterproof case and filmed inside dishwasher.
Had to insure enough fill for spray arms to rotate during wash.
Upper spray bar does not turn or seem to spray, only lower.
suspect the stepper motor is not turning the vario valve and that is the new noise i'm hearing during wash.
I'm going to purchase and replace this motor unless someone can help me with what i'm missing.
I noticed a few other posts where other models had a CXX code with just 1LO during the test mode for the vario valve.

Thanks!
