My dishwasher isn't completing its progamme has '20 on the display screen. Also found dirty water under the filter at the base of the dishwasher.

'20 is a problem draining fault code.drain sump under filter area and look to see if anything is floating about in there causing blockage.next is to remove base and drain pump and check for blockage or jammed impeller.Could also be a faulty pump or a blockage in the waste hose
