Zanussi WJD 1667 E20 advice

Hi all, ive been reading the forums and wanted a steer.

My WD did the e20 of which we cleaned the filter at the front, but its still doing it. I messed about with it, and had to empty it manually into a bucket, The flow of the water through the hose into the bucket was fine, so i hazard a guess i dont have a blockage as its was free flowing by gravity alone.

So i tipped it on its side and removed the 3 screws which i think holds the Pump. The pump was hot and seemed to rotate.
So ive ordered a new one

Can anybody advise if what ive done will cure it, or can an e20 also lead to other things.

if anybody is familier with the 1667 i dont seem to hear the slushing sound of it draining, an i right in thinking that Impellor is that such noise when it starks to suck ?

thanks all
