Won't drain, water left in the tub (F03)
What you see
Dirty water stays in the bottom, the program stops early, or F03 shows on the display.
Likely causes
Usually a filter clogged with food. Then a kinked drain hose, a blocked sink trap or drain pipe, the wrong hose height, or the drain pump itself.
Safe to try
Switch off, clean the filter (leave the black pump cover in place), straighten the hose and check the sink connection.
Technician
The technician tests the drain pump and its power supply and clears the sump before replacing anything.
