U3 error code
Getting U3 error code for upper drawer unit about 5 minutes into load process.
Have performed all maintenance steps per manual, including removal and cleaning of drain filter, filter plate, impeller and rotor locking ring. No debris appears evident yet still getting error code after next run. i ensured all parts were replaced and seated/locked into place all the way up through the spray arm and drain filter.

I believe U3 error on your model of dishwasher could also mean a couple of other things like either the drain hose has an obstruction (kink) or the inlet water pressure is not correct.
Hope this helps in finding out what could be the actual reason. T
o find the kink if any, pull the drawer out as much as possible and feel the hose. Might be better if you took the bottom drawer out from the casing and inspect the hose completely. As the problem is limited to upper drawer you do not have to worry about what is under the bottom drawer. Check the water pressure setting is same for both drawers. If so then that is not an issue as bottom drawer is working ok according to your description. See your manual for instruction on how to check the water supply pressure setting on your dishwasher.
