Hello there, I have a Bosch classixx maxx, srs43a02gb/08 or sd13h1b. The water flows into the labyrinth, then through the float chamber part (sorry if that’s not what it’s called) and after a while it sounds like it’s trying to start but the water is being pumped out again. No water coming through the spinning arms, and just a bit of water collecting in the bottom of the drain hole. I have changed both the labyrinth and the chamber with the float switches on it so that everything is clean. Any suggestions? Thanks in advance.
