Neff 24 in. S4443 Built-in Dishwasher - Answered Questions & Fixed issues

Hi,
This could be a problem with the controller as it is not waiting for water to warm before continuing.
Water element should be checked, as well as the water thermostat switch (which may be stuck on), possibly a substitute timer fitted to make sure you replace the right part.

Hi

If you are noticing that the dishes are not clean, then there are a few things to check for. Check the soap powder if it's kept in a dry environment. Also try replacing the powder with something like a gel or liquid. Next thing to check for is the water pressure and fill valve. Check if the water is filling in and the spray arms are throwing the water with enough pressure. Try and listen to the sound if you hear a proper spraying action sound.

If it seems as a low water pressure then check the fill valve. Now, check if dishwasher is draining the water or not. While the dishwasher is working check whether the dishwasher is draining and there is not much left out water after the cycle is complete. Try cleaning the spray arm with a soft brush. The water temperature plays a major role in cleaning of dishes. The temp should be between 125 and 150 F for dishwasher to clean the dishes. Hope this helps...

Hello,

Welcome to FixYa.

I`m not sure if you know the Neff dishwasher is built by B/S/H/ (Bosch).

That being said, I do have a complete installation guide for B/S/H/ built machines ( which obviously would work for yours )including custom panel instructions I can send you via an email attachment in a "pdf".

If you have reservations about posting your email on here let me know, I can give you my windows live email to contact me to send it to you.

The reason is the guide is about a 550KB file which is too large to post on here.

Let me knbow, I`ll watch for your reply.

Regards,

Macmarkus :)

they dont use a lot of salt, but take the top off the salt compartment and with a long handled spoon give it a good stir up be quick or it will start to come out.

1)check the inlet pressure.
2)scaling present in boiler tank.
3)check the arm rotaing freely.

new part on its way

make sure you still have power going to your unit. sometimes they are plugged into a regular wall plug under the sink or you can also chrck the circuit breaker @ the panel most of the on the out side of the house

Just went through this myself. It could be a latch switch. Open the door undo the screws that holds on the inside door panel remove the latch. The 2 black boxes with wires attached are the switches. Take them out (use your camera so you know how to put back together), take to an appliance parts place, and have hem check them. Mine were fine saving me $42.00. If this isn't it (as mine wasn't) check the in-line fuse. From the switch follow the wires into the electronics box (you will have to remove the cover. The fuse on mine was attached to the top of the circut board and it had two Tan wires attached, one of these wires attaches to the latch switch. I had it tested and yep it was bad for $12.00 I had a working dishwasher, saving me lots of $$$$$$$. I hope this helps..

change the input water hose to bigger size

problem is usually debris in the end angled jet of the spray arm which is used to turn the arms. take them outy and patiently clean. very common problem

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.

They discuss code 25 on this site: https://www.youtube.com/watch?v=zDHXtu-FaQg Also, here is a good video on You Tube: https://www.youtube.com/watch?v=-fQZ8p2yEJY

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

Troubleshooting

Problem: E04

Back Fault with the electronics Reason Fault with the electronics detected in the self-test. Solution Faults can only be eliminated by an experienced engineer, and we recommend contacting customer service.

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.
