Neff integrated dishwasher not draining after repair

[davidsgaunt]

I have a Neff intergrated dishwasher. Last week it wouldn’t run a cycle but just continued to run the drain pump even when switched off and door open. I located the fault to a stuck pump switch float and so have replaced the vacuum chamber completely. Since this has been replaced the machine now struggles to complete, sometimes not draining during washing ie rinse cycle and sometimes not draining anything at the end of the wash and also sometimes just half draining at the end.

Any help would be appreciated before I throw the thing out of the window.

what do you mean by the vacuum chamber ?

never needed to swop one of those, normally a good clear out sorts it

have to figure why the float switch operated in the first place
normally a water leak into the base lifts the float that pushes a ro to activate the switch or the unit over fills and operates it

which was yours

The float switch was stuck up due to gunk under the float holding it too high even when the water had drained out.

ok had that many times and just stripped and cleaned it

are you sure you put the wiring back correctly on the 2 switches

Yes identical

think i would look for blockages in the drain pipes etc

try filling with water then activate the overflow microswitch and see how fast it drains
