Bosch SGv53eo3gb dishwasher Pump runs continuously

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?

I will try and help with this problem with your Bosch SGv53e03gb dishwasher

If your Bosch SGv53e03gb dishwasher is filling up in the base of the machine then you will need to check the main motor seal, also check the pump and make sure there are no leaks coming from any hoses
