No fill - drain pump running - I assume stuck float switch

Where do I find the (probably stuck) float switch on a bosch dishwasher SHC43C02 FROM 2004?

Does the machine has to be removed from underneath the countertop to access the switch?

Thanks a bunch for your help!

Remove the bottom plate of the dishwasher and the bottom pan is revealed. reason the drain pump is running will be that this pan has water in it ie you have a leak. mop out the water and dishwasher will work - switch off mains when you do this

I have a bosch shu4303uc dishwasher and it overflowed and now has water in the tray area underneath. I have gotten most of the water out but unit will not wash will only sound as if it is constantly...


yes the problem is the float. you have to remove the left side panel and take a flash light and see the water in the very bottom of the tray. there is a little dip where the float is that is probably partially filled with water.dry that area completelyand that will solve the problem. then cancel and drain the machine
that should do it

Bosch Dishwasher won't fill with water


Certainly *sounds* like the float is stuck in the over filled position
or possible a bad float switch, if the float is stuck in the up or full position, the d/w will not fill with water and the drain motor will often run all the time

Will not drain


Check where drainhose connects to waste pipe for blockage. If OK, blockage likely to be in pump impellor.
Disconnect from power.
To access pump:
Open door and remove all bottom filters. Remove all water from inside machine. In the bottom of the sump on the left hand side, you will see a star screw- remove this screw and you can remove the cover it is holding down. Under this cover you will see the drain pump impellor (white fan blade). This impellor should turn relatively easily- check for blockages (careful for broken glass!!). It can be a bit hard to reach, but you need to get your finger right around underneath impellor to ensure nothing is stuck underneath- try flicking the impellor a few times to remove any obstruction from underneath. Once clean and free from obsruction, reassemble and test

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.

Dishwasher conrol panel light comes on but it wont go into wash cycle


All dishwashers usually start by draining first, if your machine does not detect that your machine is empty it will not start to wash. There are a few resons why this can happen, could be the pressure switch is stuck. Some machines ie bosch have a float switch mounted in the base so if your machine has leaked underneath and lifted the switch it will just stay on drain.... would help to know the make and model number

My bosch exxcel dishwasher will not drain after wash cycle


That is because the water level switch activated by the floating sensor is stuck.

You probably need to have the water level switch replaced.

Wont drain!!!


Check first the drain lines and the drain pump.

If the drain pump is working, and there is no problem in there, then the problem is usually because the water level switch activated by the floating sensor is stuck.

You probably need to have the water level switch replaced.

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.
