My Zwh7148p washing machine comes up with error code e20. Doesn’t finish a cycle. I’ve checked pump, and filter. all ok and empties as it should. What’s next?
Re: Zwh7148p error e20
e20 faults are all pump related as a user you will see E20 but if you went into the diagnostics it would give you one of the following
E21 drain problem this is the only one you could probably cure yourself. possible blockages. you have checked filter but there may be blockages in hoses elsewhere. this fault can also be pressure sensor and air chamber faults as spin doctor said but I will give it a bit more explanation. when the machine fills a chamber in the bottom of the machine traps air and the pressure of this air is proportional to the amount of water in the drum. this is fed to a small switch through a thin tube which senses this pressure. if the air chamber (pressure chamber) gets blocked it can throw up E10 and E20 faults
