Question about Neff 24 in. S5456 Built-in Dishwasher

Open Question

Neff S5456X2GB/40, around 9 years old. on Auto wash, it appears to stick with what sounds like the pump running endlessly, with either 30 minutes showing, or 1 minute showing on display, but with soapy wet dishes, and a variable amount of water above the base, or in the filters. After a reset it will then empty the base normally. A rinse cycle also works normally to end of cycle - there is about 1 inch of water in the bottom of the base when the filters are taken out, I don't know if that is normal but it always seems to have a little water in the bottom when I clean the filters. I've checked the pump impeller under the white cover - there is nothing stuck there, it looks in perfect nick and turns freely. I've checked the sink end of the drain hose - nothing stuck there, and the drain is working just fine. It is plumbed in via a water softener so uses no salt. Any ideas about what to look at next? Thanks

    Just to add - I've taken off the kick plate and steel cover - there is no water in the anti-flood tray - it's bone dry in there. What I guess is a vertical pushrod to activate the antiflood switch on the LHS moves freely - you can hear it click a microswitch.

SOURCE: Neff S5555 - empties water but stuck in draining mode.

if this machine uses an electrical-mechanical timer with cam switches, the try oiling the shaft bushings both for the timer motor and cams-the timer may be getting stuck because of dry or corroded bushings

SOURCE: dishwasher - water softener not working

Make sure your water temperature is at least 120 degrees .Make sure your heater element is working and last of all ,Rinse Aid is the 2nd most important after water temp.

SOURCE: our Neff S5454x1/21 dishwasher has occasionally stopped/stuck

Looks like the heater unit has packed up.

I cannot seem to find the actual model you have anywhere on the internet. But I am assuming you connect the dishwasher to cold water inlet and it is meant to have a heater.

Are you in UK or Europe. Bosch also makes parts for the NEFF dishwasher but I am not able to find spare parts for your exact model.

Please post a comment.

LG dishwasher model LDF6920WW 1 1/2 years old approximately. Suddenly stops a minute or so into cycle (it drains remaining water and fills with new water then get LE error). When I open the door at the...


The manufacturer has assigned this error or fault code to indicate a problem with the water circulation pump motor. Turn the appliance off for 30 minutes to allow it to cool. Then, restart the cycle. If the error code returns check the wiring to the pump motor. Also, if the wash impeller is broken this error can appear. If the impeller and wire harness check out, and the code keeps returning, you will probably need to replace the pump and motor assembly.

I have a Neff integrated washing machine, approx 9 years old. It is still taking in and draining water, although nothing else seems to be happening. The drum is not being moved (although I can move it...


A couple of possibilities here.
The drum belt could have off, or the motor is not working, possibly due to worn brushes in the motor.
Either way, it means the washer has to come out of the cabinet for you to check these things.
Please rate my solution .
Thankyou.

NEFF S5456 DISHWASHER


Have you tried it on a different program? I have nearly always used the AUTO program - however i have used the 50 degree program 3 times now and it completes the (much longer) wash without sticking on one minute. Will try it on auto again to see what happens. I found it useful to turn the end-of-wash buzzer on (to loud) to remind me when (if) it completes the program.
