We have a kenmore elite smartwash quiet pak 2 (723 wt-wt).
It starts the normal wash cycle and about 35 mins in, it will not go to a rinse cycle and it stops.Error F21 or Sud comes up. I can not proceed from there. since yesterday we have been having problems with it unlocking, it appears like it not fully draining. We cant drain wont open door tried following the operation instructions on the front tried resetting power still gets stuck at f21 / SUD wont drain
