I first experienced the 5e error a couple of years ago and found and removed the plastic tabs from the upper rack that were in the drain hose. This resolved the issue. However in the last month it has re appeared. I have removed the unit and checked everything from the hose to the pump and also removed all pieces on the inside of machine. No debris can be found and everything is clear. When the error code is thrown there is standing water in the bottom. I enter the service mode and by using the t5 mode activate the pump. It works no problem and drains the standing water. However when I re run the unit it throws the 5e code again and won't drain. I'm about to throw it out and buy something new.
