neff s5444x1gb/23 Leak

[Rosso]

Hi,

New here, looking for some help.

Recently bought a new property which has a neff s5444x1gb/23 dishwasher.

According to the previous owner it hasn’t worked in years, the unit itself is dated 2007.

When testing it, it would complete a rinse cycle however when opened it would have water pooled in it, the drain pump wasn’t working. I removed the unit (built in unit) and the pump and discovered glass jammed in the blades. Reinstalled it, tried a rinse cycle and it successfully drained 🙂

I then tried a 65 degree wash with a clean agent which also worked however at the end of the cycle (4 hours) it wasn’t beeping to signify it was finished. The pump kept cutting in so i opened it, it had drained but the float/anti flood had stuck and was causing it to keep pumping. I nudged the float and it stopped.

After checking i couldn’t see anything wrong so thought it might just be sticky so tried a 50 degree wash with a load. It started the programme but then the pump cut in after about 5 minutes and kept running. Again the antiflood had tripped. After taking the access panel off i can see a small amount of water in the base of the unit.

Any common area’s for these units to leak ? Or how i can test and find the leak ?

Thanks

if the unit is overfilling I would change the impellor jug although I would check the wires to it first ( had a similar machine last week and mice had eaten cable)

this device counts the water in. if it fails unit overfills

Hi,

I dont think the unit is overfilling as water is leaking somewhere and pooling in the base which in turn trips the antiflood.

[electrofix]

in that case take off the front cover plate and lie on the floor with a torch as it fills and look for a leak

Hi,

I have stripped the unit down and found the leak.

left hand side of machine is a water inlet system, clear plastic that runs the height of the machine. It has 5 ports at the bottom. The seal in one of them isn’t seated correctly and is leaking.

Is this fixable as i can see no way of removing it ?

[electrofix]

can be replaced
go to https://www.neff-home.com/uk/service/care-protection-and-parts/spare-parts

put in Enr number and go to page 4 of diagrams. assume you mean item 411 on diagram part number 166878

to remove the side the cover inside (see page 3 item 0307 ) unscrews anti clockwise
