I have a dishwasher from Electrolux ESF45030 and yesterday it sounded very strange. Turns out it at the end of (or middle) of a program it didn´t empty the water so the filter at the floor of the dishwasher is filled with water. I tried emptying the hosepipe under the sink and some water came out but the water in the machine remains. An error code appeared in the program window: i20. Please help!
