Frequently Asked Questions - S455HCX29E NEFF

How to clean the filters of my Neff S455HCX29E dishwasher?
To clean the filters, remove the coarse filter by turning counterclockwise, then lift out the filter system. Clean under running water and reassemble by aligning the arrows. Ensure the latches click into place.
What to do if the dishwasher does not start?
Check that the door is properly closed, the appliance is plugged in, and the water tap is open. Check the displayed error code (e.g., E:30). If the problem persists, unplug the appliance for 60 seconds then plug it back in.
How to replace the upper spray arm?
Unscrew the upper spray arm counterclockwise and pull it downwards. To reassemble, insert it and screw tightly. For the lower arm, lower it to remove and snap the new one into place.
Why does my dishwasher display error code E:30?
Error code E:30 generally indicates a drainage problem. Check that the drain hose is not kinked or blocked, and that the wastewater pump filter is not clogged. Clean if necessary.
How to change the detergent cover?
Open the cover and push it 5 mm. Lift it from the bottom of the guide rails and remove the spring. For installation, insert the spring into the fixing holes, then place the cover 5 mm from the open position and push it into the rails.
Which detergent to use?
Use a dishwasher detergent in powder, gel, or tablet form. Add rinse aid and regeneration salt. Follow the dosages indicated on the packaging.
How to activate or deactivate the TimeLight?
The TimeLight activates automatically with certain programs. To deactivate it, refer to the user manual. Generally, it can be adjusted via the control panel by holding down a button.
My dishwasher leaks: what to do?
Turn off the water supply and unplug the appliance. Check the door seals, hose connections, and the bottom of the tub. If the leak comes from the overflow conduit, replace it as indicated in the repair manual.
How to maintain the spray arms?
Remove the spray arms and clean the nozzles with a toothpick to remove residues. Rinse with clean water. Reassemble ensuring they rotate freely.
Where to find the spare part reference?
The reference is indicated in the repair manual in square brackets, for example [00614935] for the tablet guide. You can order these parts from Neff customer service by specifying the model S455HCX29E.
