Re: Neff dishwasher will not empty

Could be a kinked hose, diverter solenoid is jammed or burnt out. If the dishes are clean and the pump is working...then look at the above. If the spray isn't happening, the pump could be a problem. They are usually direct drive and you'll note that the motor isn't working.

Bosch SL1501B dishwasher doesn't drain water after the washing cycle. Also with new drain pump. What else could it be?

Check the following.
1. The drain hose has to be discharging at a high enough point to prevent water flowing back into the machine.
2. Make sure your drain hose is not twisted or kinked.
3 . Make sure your drain line is not blocked push a flexible hose down it to dislodge any fat/debris
4.If your drain line discharges into a shared drain with another appliance i.e. garbage disposal make sure it is not blocked.
5. You may have a blockage at the inlet to the pump which would slow down the pumping rate,
Since you mentioned the mushroom shaped float allowing the washer to empty this may be defective.
See the link attached.
Hope this helps.

I have a whirlpool Adp8540 that seems to go through the wash cycle completely but when we open it up the water has not gone through the spraying arms and the soap is a solid mass at the bottom of the...

It is likely the water circulation system is faulty. This dishwasher uses a single motor to run the water pump and the drain pump. If you hear the wash pump operate during wash cycle then it is likely there is a blockage in the water circulation manifold which distributes the water through the arms.

If you do not hear the pump operate during wash cycle then the sensor is faulty. The sensor tells dishwasher to switch to drain cycle from wash cycle.

Machine not empting the water after wash

The water not emptying after wash could be due to several reasons.

The filter at base is clogged or the drain hose is clogged or if you have insinkerator (garbage disposal) under sink that may be full.

It would help if you can confirm if the drain pump motor is operating at the end of the wash cycle.

Also try the reset function. Have master switch in ON position. (left most button on door top).

Then press the A & C buttons (1st and 3rd buttons from left on the cluster of 4 button on the right) together for 3-4 secs.

Hello there and thank you for choosing fixya
Ok there are acouple of things that can be checked on this along with what you have already checked
Drain solenoid Beneath some dishwashers, there's a timer-activated drain solenoid (an electro-magnetic coil) that opens a drain valve, to drain the wash water through a hose and out to the house's plumbing waste system. If this is failing it will not allow the water to drain from the machine fully
Timer Dishwashers have a timer behind the main control panel at the front top of the dishwasher, or behind the lower access panel. It is either a mechanical device like a simple clock, or it's completely electronic with just a digital readout. The timer runs the dishwasher in a pre-determined pattern. It provides the electricity to all of the dishwasher components at the correct time, for the correct length of time.

Hotpoint sdw dishwasher

It is possible drain pump blocked, you need to empty d/washer manually, check inside drain pump which is at end of drain hose, always isolate d/washer from power before attempting any work on it.

Meile G638 I Plus dishwasher

Problem solved, the dishwasher starts its wash cycle with a drain sequence, the pan did not drain in time for the wash cycle to continue , thererfor locking it out on inlet/drain alarm. I removed the drain hose from the S trap, then the non-return valve from the filter basket, made sure the drain pump impelar was free, blew down the drain hose back into dishwasher to clear any waste in the pipe,then found a block in the S trap orifis, after clearing that, reasembled and test run on cold pre wash cycle this runs for aprox 10 min.customer was very happy.
