if this machine uses an electrical-mechanical timer with cam switches, the try oiling the shaft bushings both for the timer motor and cams-the timer may be getting stuck because of dry or corroded bushings

SOURCE: Neff Dishwasher won't drain
I've had this problem a couple of times with my dishwasher. In both cases, the cause was a shard of broken glass that had managed to get past the filters and jam itself underneath the impellor. Hard to see, but easy to fix. First ladle out the water.
Pull off the lower rotor arm, unscrew the filter and take out the filter bowl, tray and cylindrical filter. Get as much water as you can out of the filter cavity.
Then, using a Torx-20 driver, remove the screw holding the impellor cover and lift the cover off. (this is the small bit of plastic at the left end of the filter cavity.) Check whether the impellor can rotate freely by spinning it with your finger several times - if it jams or grinds, then there's probably something jammed under it. (It may seem to be fine at first, so do check thoroughly, as any debris can move around with the water flow and only jam occasionally) You may have to use a cocktail stick or similar to poke out anything that's stuck underneath.
Glass is a particular problem, since it's almost impossible to see when there's any water around (it's easy to cut yourself too!)
Anyway, that's worked twice for me now - and I didn't have to even move the machine out of its cupboard to fix it.
Hope that helps.

Drain pump is either faulty or blocked, follow drain hose back to d/washer pump is at the end, always isolate from power supply before attempting any work

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

If you have hard water, glasses can look spotted and cloudy even after cleaning. Sometimes changing the dishwasher detergent can help. The easiest solution to clearing up glasses that start to look cloudy is to add some vinegar to the bottom of the dishwasher before you start a cycle. Simply add 1/4 of white vinegar and it will clear up your glasses very well.
You should see marked improvement after the first time you do this. If they are not crystal clear then simply repeat the process until all of the cloudiness is gone. In fact I recommend to using a little vinegar in each cycle to maintain the clarity of the glass.
Note: you can pre-test this by rubbing some vinegar on an individual glass with a cloth. If you cannot remove the cloudiness by soaking it and rubbing vinegar on it then it is possible that the glass is etched due to harsh or cheap dishwasher detergent and vinegar will not solve the problem.
