Had the E20 error code and after reading the help messages decided to have a go myself. The result is a repaired washing machine at no cost.
I took the washing machine onto the patio and got all the water out through the front drain and then found the small plug of fluff. Once removed i decided to put machine on a drain cycle with the garden hose running water into the machine via the front drain which cleared some of the lime scale that was building inside.So thanks to all who put previous comments that have saved me time and money.
