Hi, welcome to Just answer
How old is it ?
as you know E20 error means there is a problem with draining
if you cannot turn the filter anticlockwise to open it then you will have to pull it out to clean the drain pump assembly
after this is done clean everything and then lay it on its side around 45 degrees so that if there is any water left it comes out
really. so if we do that and still doesnt work what then
I am waiting...after you do that and still it does not work then I will tell you what else should be checked :)
looking at the age of the unit..I believe the problem should be solved after cleaning the drain pump assembly completely
well it will take a while so we will get back to you.
sure no problem
Did that help ?
were you able to solve the problem ?
