Neff S4340 integrated dishwasher seems stuck on cycle
The water does not appear to be circulating. Although the lower washer arm appears to work, the upper one does not appear to. It's not blocked so I don't think water is getting to it.
The water level remains level with the top of the filter but seems merely to circulate, i.e. it stays dirty. The machine does not turn off after the expected program interval. The filters have been cleared. Any ideas before I randomly tear it apart?

Check the center wash arm assembly. If the center wash arm isn't getting water, all of the dishes in the upper rack will come out dirty. Check to be sure the center wash arm assembly is mating properly with the water supply nozzle in the back of the dishwasher. Also check to be sure the little holes in the center wash arm aren't clogged or blocked.
* Run empty cycle using vinegar and baking soda lime scale problem will resolve.
Normally if you started the rinse cycle with water already in the base of the dishwasher it will immediately go into circulating the water through the wash arms. Do you hear the wash arms running when the washer is stuck at 11mins? Also when the washer is stuck at 73 mins are the wash arms running all the time or do you hear the pump operate at some stage? If you have the dishwasher manual available make sure the water pressure setting is at HI or LO depending on your rated mains water pressure.
check water going into unit. disconnect to make sure there is a strong pressure going through.
check the water valve with a meter if there is continuity the valve is good. if not the valve is bad a no water water will go through. let me know if this helps
I Have the same issue, it sounds like the arms try and start up 4 times then each time power back down, the top arm is not spinning at all. On the fifth time a I hear grinding and then the mid and lower arms spin, soap streaks down the door, nothing stuck in any of the arms, 16 months old, 750.00 out of pocket for junk!
Sounds like you have a seal or impeller problem. Its not so user friendly to try and tackle this one. I suggest that you try to contact an expert to do the job for you. I believe this is a common problem for Bosch dishwashers.
Well, another possibility is that your check valve (stops water from coming back) is busted. This seldom happens but you might want to check it out. I hope this helps you in isolating the problem.
Don't know about yours but many of the rotating spray-heads are turned only by waterpressure, not a separate motor.
The rotator is normally pretty loose and should turn willingly by hand; if it seems stiff and your water pressure is normally lower (most city lines are ~60#, rural from 30-50#) it may not have enough pressure to turn the spray head if a buildup of food has happened.
Not having a motor drive isn't a bad idea because if the washer is carelessly loaded, the worst that happens is no spin, instead of trashing dishes or the machine mechanism.
make sure all filters are clean.make sure the wash arms are not cracked at the seam.if all that checks good you could have an obstruction to the pump.also check to see if you lose any water when running a cycle because the drain valve may be stuck open.the other possibility is that the impeller on the pump is worn or broke.
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
