This can be the result of a relay switch, that is the brain that runs the unit. You may want to try shutting of the power to the dishwasher, wait about 5 min.s then turn the power back on. Sometimes by doing this it can reset it self. I hope it works.

SOURCE: Drain Pump

The machine is over filling because the fill sensor is blocked with debris Somewhere low down on the body of the machine there is a small bottle like object clipped to a small pipe coming from water tank , from the back of this will be a small plastic tube going to a dish like object somewhere high up. This is the fill sensor. The bottle like device is in all probability blocked with -grunge- a combination of grease/detergent/scale -it needs removing and a good clean out.

SOURCE: dishwasher pump will drain but not force water into spray arms

If the washer is not used regularly the shaft can stick to the seals and prevent the motor from spinning. This happens quite regularly for me if I don't use the washer often. You can just take off the bottom panel - after shutting off power to the dishwasher - and access the motor. you should see some fins and then just try to spin the motor by hand. It usually takes about 90 degrees of rotation before the motor breaks free from the seal. You'll have to fight through the spring-like resistance created by the seal-shaft adhesion. After it breaks free the motor spins freely and you should be all set to go. I haven't found a more permanent fix for this other than running the dishwasher more regularly.

SOURCE: won't start

It sounds like you have a food blockage or some blockage between where the water fills up and where it goes into the pump you need to take out the water wand (the rotating thing with water coming out) only the bottom one. You need to unscrew the water wand and make sure nothing is blocking in there.

If not then check your filter which should be next to the water wand remove it and then clean it and make sure nothing in in there to block water getting through.

If you have any questions please dont hesitate to ask

SOURCE: Our PLD4375RFC2 dishwasher fills up with water but doesn't run

no their is no fuse. sound to me like your motor is not working, however
the pump should still drain out.push cancel only and unit should drain if it does then id say motor bad. you can try to take apart and check motor blade ive seen toothpics, food , other objects hold motor impeller from turning making it seem like its the motor but actually its just stuck..remove btm wash arm and filter cover thentake two or 3 small screws from a plastic cover covering motor impeller, look to see if anything is in their if so remove. warning if you see a white ball down their leave it alone reinstall and see what happens. hope this helps.

SOURCE: water wont fill

first of all, i'm gonna guess that the water supply under the sink is turned on.
the water you hear is the left over water from a previous cycle. there is always some left in the hoses after it drains, just like your washer.
this is 1 of 2 things. either your float is stuck in the up position or your water inlet valve is malfunctioning. the float is the quick and easy fix. the float is somewhere inside your dishwasher. it tells the water to stop coming in when it reaches a certain height, just like your toilet. it could look like anything, but most likely a cone or a little hat. just grab it and try to move it up and down. it should slide freely. it was probably stuck up and your handling will have solved the problem. we hope.
if the float was ok, the inlet valve needs checked or replaced. it is under the machine and has the water supply line hooked up to it. good luck

The control lights are not on and dishwasher won't start

What make and model are you referring to?

When I push auto and start the lights go on and the time, but then it goes off. Why?

Hello. Is this unit less than 1 year old? If so, anything defective is covered under the warranty(parts and labor). After 1 year, certain parts are covered, however, no labor is covered. Make absolutely sure the door is closed properly--there is an internal door switch that must be closed(tells the main board it's okay to start the cycle) or nothing will happen and produce the exact symptom you describe. Next, the unit could be experiencing an error condition causing the shutdown. Make sure the water supply to the dishwasher is turned on(and always run the hot water in the sink before starting the dishwasher to ensure hot water gets to the unit). Next, do you hear the drain pump working? A lot of dishwashers turn on the drain pump immediately to remove any standing water in the pump before letting in fresh hot water. If the drain pump is jammed or clogged, you might hear a soft humming sound only(from the motor trying to spin) and then the dishwasher will shut down due to it detecting a malfunction. Check the float switch in the tub to make sure nothing has gotten underneath it(ex. a spoon or fork can become lodged underneath and the dishwasher thinks there is already water inside and won't fill) I hope this helps you!

Why won't the water stay in the basin of my dishwasher? Why does the water run out of my dishwasher as it is trying to fill? The fill valve opens, water runs into the washer and directly out of the dr

There are two ways water can get out of your dishwasher. 1, it the tub is cracked and the water leaks out. If that were happening then you'd probably already know since there would be a lot of water somewhere it shouldn't be. 2, if for some reason the drain pump is "stuck" in the on position and is running while the fill valve is open. You could check this by turning the water to your dishwasher OFF and then set it to run a load. When it attempts to start you should hear the valve open and nothing more. If you can hear the drain pump running then you've narrowed the problem this far. The next step would be confirm that all mechanical switches (and/or relays) are operating correctly. Finally, you may want to look up a schematic/wiring diagram for your model and see if it shows any mechanical switches that control the drain pump (like a "high water level" switch) that could be stuck closed. Hope some of this helps.

Flashing but nothing happening

A-- If you hear the water filling for 3 minutes before the lights flash, 2 things could be happening:
a.1) water never reached the proper fill/run level so the computer prevents the heater from starting and alerts the user. There should be a code list in the troubleshooting section of the user manual describing the blinking lights and what they mean.
Solution- verify by sound if water flows at the same rate as the sink tap, if not then shut off the water and check the inside the connection hose for debris against the screen inside the hose end or insid ethe machine end where there is a intake valve. The debris keeps sediment out so it works but there's no auto cleaner for the screen.
a.2) Otherwise the heater itself is faulty meaning it does not conduct an electrical path or maybe overheating (could be dry) and the computer senses the wrong temperature either too high or too low.
Solution- A service call to determine the reason why; heater continuity, water valve, heater relay, hi-temp fuse, etc.

B-- Now, if you do NOT hear water filling for those first 3 minutes, 3 things could be happening;
b.1) House water supply is turned off.
b.2) hose is clogged (see solution a.1 above)
b.3) Drain pump inside dishwasher was clogged during the last run and old water didn't drain out (maybe some water is evident in the tub bottom).
Solution- Most dishwashers start each wash cycle with 30 second drain pump running to make sure the tub is completely emptied so the next fill cycle can't overfill. This ensures that if the user finds a 3 liter pot that flipped over during the last wash and if they dump that full pot of water into the unit to make it lighter, that the water will get drained before the new water enters the tub.
If the drain pump is clogged reset the power and restart the wash cycle. Note how much water is in the tub and see if it goes down any during those 30 seconds by opening the door afterwards. Find the clog either a bone or plastic bag or some small pice of a childs toy is stuck in the drain pump or the other end is clogged maybe by grease or bones if you have a sink disposal unit. The things they grind up drop into the drain 1" inch above the hole for the dishwasher drain tube.
NOTE: There is also an overfill [float] switch if the water inlet valve gets stuck open and the water keeps filling, the drain pump is switched on until someone comes and shuts off the water supply. When the tub drains the float drops and the drainpump stops. This will also make lights blink so check the user manual for codes or call the factory service reps [1-877-337-3639].
Either way, there should be instructions to reset the machine for restart. If it doesn't reset you need someone to fix the control that tripped the unit, maybe a safety fuse or a broken piece of the puzzle.

Machine starts fills Ok but when it clicks on to start the wash pump, nothing happens, I can hear a faint hum. When cancelling wash and starting new wash it pumps out ok too. After rinse cycle it indicates...

sounds like your main circulation pump is not working, if it is humming when it is supposed to start, sounds like it is getiing power, so probably not the control circuits, can you measure voltage to pump?
if you are getting 120 there, probably pump motor is dead

We have a neff dishwasher and the pump is draining all the time (even when the door is open) but there is no water in the dishwasher. Is there a way to stop the pump and reset the setting for the flood...

Hello,
The water which has activated the antiflood device is actually underneath the appliance it is held in the sump tray and this has to be drained before the A.F.D.will cancel.You will have to remove the dishwasher to get at the underneath but when you have got rid of the water you will still have to trace what caused it.The seal on the circulation pump could be a suspect or a pin hole in the drain hose.

Hope this helps.

Neff s5946 slimline built in dishwasher. Fills with water, clonking sound in pipe and does not register on programme, although pump working.

if you only hear the clunking sound while the dishwasher is filling then the inlet valve is bad.. i would replace it because if it fails completely you could possibly have a flood..

Won't start

It sounds like you have a food blockage or some blockage between where the water fills up and where it goes into the pump you need to take out the water wand (the rotating thing with water coming out) only the bottom one. You need to unscrew the water wand and make sure nothing is blocking in there.

If not then check your filter which should be next to the water wand remove it and then clean it and make sure nothing in in there to block water getting through.

If you have any questions please dont hesitate to ask

Dishwasher not working

Nothing by the sound of it. The humming may mean the main pump is stuck. If you are able, remove the pump & turn the impellor by hand (or screwdriver) just to make sure its free moving. Put it back into machine & see what you get. Could also mean that the capacitor on the main pump (if it is a capacitor start motor) has failed.
