Zanussi FJR 1454W Jetsystem 1400 showing E20. Machine is stuck on 22 mins?

I would appreciate knowing what error 20 is. My washing machine is full of clothes and sudsy water, and is not "moving on" , 22 minutes continuing to appear on the timer. We re set it after the error warning came on, but it re-spun for a fairly short time before stopping and the erro warning repeated. Please help.
