Question about Neff 24 in. S5555X0GB Built-in Dishwasher

Not filling with enough water

My Neff has been cleaned, filters checked and as best as i can back flushed.
If left to it's own devices there is not enough pressure to spin the arm and the water level appears low.
If I add approx 3L of water after each water filling part of the cycle the machine works fine (not v labour saving!!)
So I deduce that a water level float is closing too early... am I on the right tracks and how do I proceed???
Thanks in advance

    Ronidavey,

    Thanks for you advice. I have done as you say (ish) I have started the machine with the cover off and watched the red and yellow floats do their work. Every thing seem to flow well. The water seems to fill up the red and the yellow chambers and then the water is extracted for a while, which causes the floats to drop, this happens several times during the fill. Does this help anymore?

    roni davey,


    Sir you are a superstar!! The pipe was full of silt, which is strange considering we have an apparent water softener fitter to the mains... or is this another investigation??? Anyhow the dishwasher is now happily blasting my wifes china!!!

    Please have a cyber pint on me and very many thanks for your assistance.

If you remove the lid and looking at the front of the d/w take of the lefft side panel, at the right bottom on the side you should see a pressure chamber with some micro switches and a red lever. This is possible blocked along with the hose that is attached to it (to the right, behind the chamber) clear them both and retest with the side panel off to check for good flow and to make sure you have not created a leak.
Good luck

    The red float should not move during the fill, it is an overfill float. I'm going to put money on the hose attached to this chamber being restricted in some way. Is there any gunge or lime build up in the chamber? If so you need to replace it or take it off and clean it. (be careful not the get the microswitches wet. It will come off by first removing the fill chamber on the left and then give it a hefty tug upwards. Best of luck.

    Follow the link above, go to page 4, the part numbered 0415 is the hose that I believe is blocked.

The opaque flexible convoluted plastic pipe from the filling float chamber behind the left-hand side panel to the filter chamber under the filter in the bottom of the machine was almost completely blocked with hardened gunge. This gunge ( which I suspect is dishwasher powder,tablet detergent residue ) has built up over time and set like concrete in the pipe, needing a screwdriver to break it up and remove.
Best to remove the pipe which just pulls off at each end in order to clean it out.
partial blockage of this pipe causes the filling water to back up, filling the float chamber which operates the empty-out pump and shutts off the filling water so the machine does not take on enough water before starting to rinse or wash. Insufficient water intake causes the spray from the spray arms to reduce to a trickle so does not wash effectively.

Neff s5443x1GB/29 dishwasher starts and stops


The pressure chamber or hose (pressure chamber to sump) may be blocked and the microswitch is being activated because the water is not entering the tank quick enough. Isolate from electric, remove lid and left panel (looking from the front). There is a plastic chamber bottom right of left side with two microswitches, either this is blocked or the hose that runs from it to the right and along the back of the kick panel and into the sump. Clear either or both (make sure all hoses are pushed true when repositioning).

Dishwasher deposits grit on inside of glasses on top rack


Hi, it sounds like your either using to much soap or the water is not hot enough. Use alittle less soap the next time and see if you have the same problem. Check the water temp after you machine fills for the wash the temp should be 120 or higher.
Clean out the filter and the back flush arm. Also clean the wash arms (every little hole.)

When I flush the tank only half empties and not enough flushing action is the result as well as the bowl does not adequately fill after the flush.


Hi, if you remove the cistern lid and flush the toilet, look at the float (back left) to see if this is rising freely when the water fills back up. Once the water has stopped filling, check the fill level lines on the large syphon in the middle of cistern. Your model of toilet has an eco flush which will be lowest line to save water, so not as much water will flush out. There is a long plastic screw on the float (back left) which you can turn to adjust the water level to the higher line on syphon (1.6 gallon flush) and turn it slowley till the water level reaches that mark. flush a couple of times to see it is filling back up to the set amount.

Do I have to run water after changing filter?


Unless you want ice and water with little black flecks in it, you should flush the filter before you install it. They have loose particles in them. In the sink, fill a container deep enough to submerge the filter completely. Place the filter into the water and allow it to fill completely. (The bubbles will cease). Remove the filter and drain. Replace the filter into the container, other end up, allowing it to refill. Drain as before. Now install. Flush a gallon of water or so through the water dispenser. This should remove the remaining particles so that they will not wind up in your ice maker.
Best regards, --W/D--

The dishes are not coming out clean and the soap gets stuck


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...

My neff dishwasher is not filling with water


Hello

Water inlet valve is responsible for filling water in your dishwasher, when that goes bad either the dishwasher wont fill at all or will fill the water slowly. Please check the inlet screens and also try to clean the water lines for any clogs/obstructions. Please get back to me if you have any other questions.

My dryer continually bleeps and says empty container or filter. My m/c is hooked up at back so container never fills and filters are clean!


When you say the filters are clean, do you include the condenser box? (bottom left flap on front panel) If not, take this out, it can be cleaned under a tap or outside hose. The float device in the pump reservoir has to be activated to give the signal that the container is full, there are a few possiblities
1.the pump is broken or blocked and the water is collecting in the base.
2.the drain hoses are blocked, take the drain hose out of the standpipe and blow down it, if is is clear you should hear the collected water in the base gurgle.
3. the float switch is stuck due to fluff build up from waiting too long between flushes of the condenser.
if possible put a very damp teatowel in the machine, once you have checked the above, and check that water is actually being expelled by putting the hose in a bowl.
Hope this helps.

Bowel cleaning


Check the ports under the rim and make sure they are not clogged. To do this you can use a nail or pin to clean them out.
Right under the rim of the bowl are these ports that allow the water to flow into bowl in a turning motion to aid in flushing and cleaning wall's of the bowl.
Inside the tank check the fill tube and make sure it is connected from the fill valve to the over flow tube. Also check the fill level in the tank and make sure water is up to the line on the fill tube about 5/8" from top of tube.
