Error i20 after several drain attempts
Electrolux Dishwasher ESF66860WR
When I start any washing program the drain pump starts running several times for about a minute, then it shows error i20.
Drain pump itself works perfectly, if I add some water in the machine it goes away. I've opened the drain pump just to check, it is clean and looks OK.
I guess there should be water level sensor which may become dirty, but I can't find it.
Does anyone have an idea what could be wrong?
Thanks in adance for any help!
