20 Most Recent Neff 24 in. S4457 Built-in Dishwasher Questions & Answers

Remove the filters and look into the sump (if the back of the sump is 12 o clock) look at approx 2 oclock and you will see a hole that draws the water in to the circulation pump (sometimes covered with an extra piece of plastic that can be clipped off) put you finger in there and see if you can feel any obstructions, if so remove. (you may find that cling wrap or a dishwasher tab packet has got in there and is stopping the motor running to full capacity and/or making it noisy). Maybe take the spray arms off and check the holes in them are not blocked, as this will also cause strange noises.

Could be an over fill issue causing water to leak into the base. What you need to do is pull the dishwasher out and lay it on its back and this will allow the water to drain out from the base.

Shouldn't be a problem. Top up with salt as soon as you can. That will avoid streaky glassware.

It sounds like there may be an issue with the control board or programming of your NEFF dishwasher. The fact that the impeller runs and the rotor arms spin when water is manually added to the sump, but the controller does not call for water when the sump is empty suggests that there is a problem with the communication between the control board and the water inlet valve. The round white device you mentioned that is located in the water inlet before the water inlet valve is likely a flow meter. It is used to measure the amount of water flowing into the dishwasher and send a signal to the control board to indicate when the appropriate amount of water has been reached. This device could be malfunctioning and preventing the control board from requesting water. It's also possible that the problem is with the level float and plunger that operate the micro switch you mentioned. If the float and plunger are not working correctly, the control board may be receiving incorrect information about the water level in the sump and preventing the dishwasher from filling with water. It is best to check the user manual for the dishwasher, it will have the troubleshooting section, you can try the solution mentioned there. If the problem persists, it is best to contact NEFF customer service or an appliance repair professional for further assistance.

That is the classic behaviour of a flood sensor being wet. You said 'anti flood float'. I know them as a small sensor in a tray under the machine and above the floor in a plastic pan. If it is that where your float is, then you need a service call to diagnose. It is likely to be a circuit board issue and they are expensive so need proper eyes-on trained diagnosis.

I suggest looking under the sink. Some dishwashers simply are plugged into an outlet under the sink.
It very well could have came unplugged.
If that isn’t what it is most likely a breaker has tripped in your breaker box. Try to identify the tripped breaker. Switch to the left and then to the right. Check and see if you now have power.
If neither of these, I would suggest calling a appliance repair technician.
I hope this information helps. Have a blessed day!

Taken From the Manual (https://media3.neff-international.com/Documents/9000816278_I.pdf) If the appliance stops during dishwashing or does not start for no obvious reason, first run the Abort programme function (Reset). Terminating the programme (Reset) 1. Open the door. 2. Press START button 9 for approx. 3 sec. until all displays go out. 3. Close the door. The remaining programme sequence for draining the residual water takes approx. 1 minute.
