Bosch shu9925 At the start of the cycle, the washer is in pump mode. It remains that way. No water flows into the washer.. It just continues to pump. We checked the drain, some debris and checked to see how the pump was working, it is fine. Any suggestions?

Take bottom front panel off to expose the bottom tray. you will find there is water in it. mop water out and appliance will operate ok. turn off at mains first.

if fault reoccurs, you have a leak which will have to be traced

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.

Bosch Dishwasher Does Not Drain

Cycle starts, but does not fill with water


When I start a new cycle, I first hear the pump run to empty out all remaining water, and after that I hear the motor run for the regular washing cycle, but there is no water in the dishwasher. After a few minutes, the cycle stops, and the washer claims the dishes are 'clean'. When I try starting a new cycle over and over again, about one in 20 times, the cycle will run normally with water. But then the next time, the problem starts all over again. Once a cycle starts correctly, everything works fine, including the rinsing.

Bosch dishwasher shx46a06uc-30


the unit will try to complete the last command it was engage in before it went in the overfill safety mode. you must perform a cancel drain cycle to reset unit to default setting. Remember the drain cycle is 2 min and must be completed to reset main control. however if it went into a overfill status you have a leak and it generally comes from the pressure chamber on the lefthand side of unit where the water enters tub

Bosch dishwasher starts, pumps, stops and says it's clean


We have the exact same problem with our Bosch SHE5AL06UC/05 dishwasher. Works great when it works, but we are increasingly having a hard time getting the wash cycle to start.

Hi My dishwasher seems to get stuck in a cycle when you start it - it lets water in for around 20 secs - then pumps it out - then lets water in for say 20 secs then pumps it out - over and over and...


Hello Gerard,

This is an overfill 'fault' generally caused by one of the following:

1. Faulty or incorrectly installed flow-meter
2. An airlock in the fill chamber
3. Faulty float switch (less likely)

There are some simple checks you can do to determine the cause of the fault and hopefully solve the problem without replacing any parts - no tools required at this point.

First, open the door, pull out the lower basket and locate the float. This is the 'mushroom' in the base of the washing compartment:

belectric_200.jpg
With the washer empty of water, make sure the float is fully lowered. There should be a gap of 2-3mm between the float and the base of the washer and you should be able to lift it about half an inch / 12-15mm. When you lift it, it should fall when you let go. If it's raised when the washer is empty, it should not rise again on its own when pushed down.

If the float seems to be working correctly, the controller is receiving erroneous signals from the flow-meter that the washer is full or overfilled. This causes the washer to pump out - then resume the fill cycle because the water level is too low to start the wash. If this is caused by an air-lock, there is a simple trick to clear the air-lock and, therefore, the fault.

1. Start a wash cycle and keep you finger ready on the power switch on the control panel.
2. As soon as you hear the pump start during the fill cycle, interrupt the cycle by pressing the power switch to the off position
3. Wait for about 10 seconds, then switch the power on again.

The machine should resume filling rather than pumping out. Keep your finger ready on the power switch and repeat steps 2 and 3 until the washer is filled and the washing cycle starts. If you can get the washer to run a cycle using this trick, you may not need to do anything else, but you may need to repeat the procedure described above at the start of the next few cycles.

If the washer does not resume filling and continues pumping when you switch the power on again or you have to repeat the procedure above at the start of every wash cycle before it will run, you will need to check the flow-meter and, most likely, replace it.

I'm happy to provide step-by-step assistance with checking and replacing the flow-meter if required, but please check the float and try the simple trick above first, then let me know if you need further assistance.

Hope this helps.

Regards,
BElectric

The washer floods at the end of the cycle the pump is working this i know because when i manualy lift the mushroom float it pumps out could it be that there is a membrane in the mushroom float that is...


Hi there,

I'm not entirely sure what you mean by "floods at the end of the cycle". Is water leaking from the washer and where from?

The mushroom float isn't a water level sensor to determine when the washer should pump out. It's a second level safety feature to prevent flooding if the washer overfills. The flow meter regulates the water level in the washer.

Your pump is obviously working and there is no blockage in the drain hose, etc as the water pumps out when you lift the mushroom float. It sounds like the pump isn't receiving a signal from the controller to pump out at the end of the wash cycle. Lifting the float bypasses the controller and runs the drain pump.

Please try the following simple test:

1. Switch the programme selector to "Off"
2. Empty a bucket of water into the bottom of the washer
3. Turn the programme selector to any wash cycle
4. Press and hold the Reset button (start/stop) for at least 3 seconds. The washer should drain.

Please try this test and let me know if the washer pumps out. Please can you also be a little more specific about how and where the washer is flooding.

Thanks,
BElectric

I need a user's manual for SGS5302 bosch dishwasher. Otherwise would you tell me exactly how the aquastop works? Is there any method to bridge it? What goes on the wires? Signals from or to the...


Please rate this solution if you find it helpful. Thanks!

The Aqua-Stop function is a flood protection feature. You really don't want to be "bridging it"!

It works by using a float switch to detect when the water level gets too high in the wash compartment. It over-rides any wash programme and starts the pump to empty the water out.

Also if water leaks into the bottom of the dishwasher (under the washing compartment) the float will rise with the water level and when it reaches a critical point, it will over-ride any washing programme and run the pump.

However, the pump cannot remove water from under the washing compartment, but as it over-rides the wash programme, it prevents the washer from continuing with any wash cycle, thus preventing any more water from leaking into the bottom of the washer and flooding your house.

For this reason, you should never attempt to "bridge" (whatever that means) modify or disable the aqua-stop feature. If it's been activated, you have a problem which needs to be resolved before you continue to use the washer.

Water left after finishing wash


I have a Bosch Dishwasher and the E-Nr is SGS4362EU/03. The machine is approximately 4 years old, in good condition and has been working very well. Suddenly, there is water remaining after it completes a 50 degrees C wash cycle. This is also evident with the pre wash cycle and the 65 degrees wash cycle.

I have checked and cleaned the filters. I have loosened the internal pump white cover (Torx T 20 screw) and checked for any physical blockage - none. I have also checked for any drainage hose kinks - none.

I have tried a series of empty washes and the machine drains the water during the wash cycles. The dishes are also have a dull colour and show show signs of not being properly rinsed during the wash cycle.

Please assist.

Reagrds,

Brian

Bosch SHU43C


My SHU43C is just over 3 years old. I had a similar problem recently. First, there were a few floods. Then, the Bosch only drained non-stop. Even when I used the Cancel Drain buttons the drain pump would run without stopping. When I tried to run one of the cleaning cycles, no water entered the machine. Corrective: I removed the base plate, and saw that the red plastic floatation device was in the up position. Using a flashlight and a wooden spoon, I lightly toggled the red float stem down. I pushed regular clean cycle and kept toggling with the red float stem until the rinse water started to enter the machine (turning the red stem seems to also actuate a step in the program). Now the dishwasher runs normally. Voila!

Bosch dishwasher


is all the water draining from the tub? if not the pressure switch will not reset and it will continue to try and clear it self...check drainage system.
2. pressure switch is jammed on..build up in the sensing chamber..common..or switch faulty...rarely
3. if water is in the bottom panel most have a flood switch which automatically operates the pump in case its over filling
