Neff S5443X2UK/01 Main Circ Pump Compatible

[Varoshiotis]

Hi All, I need your help again!
I have a Neff Dishwasher and I think the main Circ Pump has failed; it goes through it’s cycle but the plates are not washed. I over rode the door and the water is just trickling out of the swinging arms (almost nothing from the top), so I assume the Pump has had it. To buy a new Pump costs £130 – £200, which is not economic. The other option is to buy a faulty 2nd hand Dishwasher and swap the pumps (having checked that the faulty one does not involve the main Circ Pump). My question is where and how can I check for compatibility between Neff Model Numbers?
Thank you
Chris

Hi Dave, I think you are spot on.
Taken the Pump out and electrically seems to be fine (nothing untoward, reasonable resitances etc.). I can rotate the main spindle but the small impeller does not rotate! Dismantled it and I think either the bearing or small rubber seals have gone or something else which allows the impeller to move vertically and so get out of lock. A Kit (such as you suggested) appears the way forward.
THANK YOU!
Chris
