I have a guide here that covers problems with the drainage functions and also the float switch. It is on the left side as viewed from the front, and it's behind a panel held on by 2 - T-25 screws. Be careful that you do not break the plastic holding the switches in when you take it apart. you will need to clean the float thoroughly.

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

Bosch dishwasher overflowing


Check the float. The float is a mushroom shaped item on the bottom of the DW. Gently Check to see that it moves freely.

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

My Bosch dishwasher is not draining. Anything I should check before I call in repair?


Hi,

There is a simple test you can do. Turn the power on and open the dishwasher door. In the bottom of the washing compartment near the centre you will see a dome/mushroom shaped plastic object (the float). Lift the float as high as it will go (about 1-2 inches) and, keeping it lifted, see if the pump starts.

If nothing happens, then it's likely that you need a new waste pump. If you can hear a faint humming, but the water doesn't pump out, then your pump impeller may be jammed or the impeller may have come off the drive shaft.

Try this test, post back with the results and I'll try to assist further . . .

When starting the dishwasher there is only a hum but nothing else happens


The first thing a Bosch dishwasher does when you start a program is run the waste pump. This ensures that any residual water and waste is removed from the machine before the wash program begins.

The hum you can hear is most likely the pump motor trying to drive the impeller. This can become clogged with waste and seize up, preventing the wash cycle from starting. There is an easy way to check this:

(It's easier to do this with the washer empty)

1: Select a wash program

2. Press "Start" and wait for the humming noise

3. Open the door and pull the bottom basket forward or lift it out completely

4. Find and lift the float (the plastic dome/mushroom in the bottom of the washer) all the way up

5. Keep the float lifted and the dishwasher should pump out. Stop if/when you hear a gurgling noise as this means it's empty and pumping mostly air.

6. If the pump doesn't start, lift the float again for about 1-2 seconds then let it drop again for 1-2 seconds. Repeat this 10-20 times and see if the pump starts. The repeated stop/start signals to the pump motor can sometimes free a seized impeller.

If the pump does start, keep lifting and dropping the float switch (1-2 seconds each time) to see if the pump starts every time. If it does, you should be OK to use the washer, but further action is needed to stop the problem returning.

When you've done all this, post the results here and I'll advise you what to do to fix the problem or prevent it from returning.

Shu3302uc/u12 will not pump out


It's most likely a seized pump impeller/motor bearings or a burnt-out pump motor. There are some simple tests for the pump that anyone can do:

A. If your washer is full of water:

1. Select a wash program and press start. You should hear a low humming noise. If you can't hear anything, you probably need a new pump, but try the next step before you start buying parts or call an engineer.

2. Open the door and pull the lower basket forward or lift it out completely. Find and lift the float (the plastic dome/mushroom in the bottom of the washer) all the way up. Keep the float lifted and the dishwasher should pump out. Stop if/when you hear a gurgling noise as this means it's empty and pumping mostly air.


B. If your washer is empty of water:

1. Select a wash program and press start

2. Open the door and pull the lower basket forward or lift it out completely. Find and lift the float (the plastic dome/mushroom in the bottom of the washer) all the way up. Keep the float lifted and the dishwasher should pump out. Stop if/when you hear a gurgling noise as this means it's empty and pumping mostly air.

C: If you can hear the low humming noise but the pump doesn't start when you lift the float:
1. lift the float again for about 1-2 seconds then let it drop again for 1-2 seconds. Repeat this 10-20 times and see if the pump starts. The repeated stop/start signals to the pump motor can sometimes free a seized impeller.

If the pump does start, keep lifting and dropping the float switch (1-2 seconds each time) to see if the pump starts every time. If it does, you should be OK to use the washer, but further action is needed to stop the problem returning.

When you've done all this, post the results here and I'll advise you what to do to fix the problem or prevent it from returning.

BOSCH DISHWASHER Flooding


Removing the water level sensor it is not a difficult operation, it is held with one bolt at the base of the floater arm.

The problem is that you cannot be sure that the floater is not working unless you find out that the floater is filled with water or stuck.

There is an electronic test to verify if water level switch activated by the floating sensor is working. Instructions here: Bosch dishwasher helps.

You can find replacement water level switch , and schematics on websites below:

Dishwasher will not fill with water


without a brand or model number its hard to be sure, but some types have a float cut out switch inside the washer. Its on the bottom inside and kind of resembles a plastic mushroom. The top should lift up and down easily. detergent will clog it up and keep it from moving. Just clean all the soap caked on it and move it up and down to see it it pushes a little switch underneath.

Prgramme not starting or finishing


The "mushroom" bottom is just a lever that operate a switch. It seems that a part of the switch's mechanism is broken or release.
