Hi all. Ok here goes. I have a Zanussi washer/dryer WJD1667W which throws up error code E20. After many months of research it seems to be a drainage fault. I have had the machine in bits and cleaned 99{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of all pipes and orifices and removed a lot of built up gunk. Both pumps stripped, cleaned and checked. No loose wires found.Washing part is fine. Tried the dryer the other day, fine. Tried it again, E20. Turned it off and on again no code dried fine. Ok experts over to you. Cheers. Russ.
E20 error coming up during the dryer cycle means the condenser unit is blocked with fluff. To clean it correctly you will need to remove the rear half of the cabinet in order to access, remove and clean the unit. Have fun!*
