Bosch dishwasher keeps emptying and filling, how to diagnose the fault and replace parts
Your Bosch dishwasher is over filling or just keeps filling and emptying with water? This video will show you how to diagnose the fault and replace the faulty parts in your Bosch dishwasher.

Bosch dishwasher keeps emptying and filling this video will show you how to diagnose the fault and replace the flow meter (impeller jug) water valve and also we will show you how the float safety switch system works.

If your Bosch dishwasher is over filling or constantly pumping out is a good indication that the flow meter or impeller jug has gone faulty. It can also mean that the base of the machine, where the electrics are, is getting water into this compartment and therefore due to safety reasons the machine´s safety switch floats, and therefore pumps the water out of the machine to stop the machine actually flooding the electrical compartment.

You can see here some of the components of the dishwasher, where the base float switch is, and the water valve that goes into the flow meter.

    Hi there, I have a Bosch SGV53E03GB and the anti-Flood chamber is filling up. Having cleaned the float switch and removed the water, the same problem has reoccurred again.

    I assume the dirty water is getting in from somewhere, any ideas?

    Hi

    I have a Bosch sms65 e dishwasher.

    The dishwasher was working OK until our water softener had a fault so was feeding the dishwasher with hard water. I picked up the fault with the softener due to the DW not cleaning plates and glasses properly.

    While I was waiting for the softener to be repaired I filled the salt container with salt which was the first time that I have done this so the DW had soft water to work with. The dishwasher then came up with a check water light along with a error code. Reseting the machine cleared this. but the fault reappeared.

    I then did an intensive cycle wash to try and do a deep clean and the DW came up with a different code maybe E24.

    I then pulled out the DW and moved it around to discount the plug and after doing this the DW doesn’t power up. I was a technician so understand electronics. I have taken off the front panel to check the power switch. Power is going in and out of the switch but no display is coming on. Can you give me some advice on what steps to follow to fault find? Is then a sensor such as a float that may be cutting off the power to the control board?

    Many thanks
    Tony
