replace water pump neff diaswasher s4453n2gb/01?

Hi chris, I presume you mean the drain pump and not wash pump. Also I presume machine is integrated. Heres how :- Unplug the machine, remove the decor door and outer door panel,remove filters and drain all water from inside the machine,remove steel inspection panel at bottom front of machine , you can now see the workings, remove clear plastic hose that runs from middle to left of machine, now you can see the pump on left it is a twist on bayonet fit,it has a locking clip at the top, push down clip and rotate pump clockwise to remove. NOTE when fitting new one make sure it is pushed on squarely and all tabs engage, easy to only locate 2 tabs and water floods out on test (dont ask me how I know !) Cheers
