Bosch SGS43C12GB/16 drain pump constantly on

[FunkySi]

Hi

I have a Bosch SGS43C12GB/16 dishwasher & it isn’t working properly. When I start it up, it makes a lot of noise and drains, but won’t fill. If I open the door, the drain pump keeps running.

If I give it a bit of a shake, it sometimes starts working, but will then get stuck on drain again later in the cycle. I think there is a problem with the float switch – it may just be crudded up – but I don’t know what to do. How do I go about getting inside the dishwasher to try & clean out the gunk?

Thanks
Simon

Tray under the machine has water in it and the flood protection system is operating. Power off, tip the machine over to one side to drain the water, then find the leak.

Bingo! You’re sensational!! 🙂

Different DW (Bosch SGS 5302 GB) but I found my leak at the water inlet connection. A constant dripping from there when no water was being pumped has obviously filled the tray and kicked the flood protection into action.

We moved house a few days ago and either during the move, or the fitting of the dishwasher into its new recess must have knocked the pipe enough to loosen it slightly.

Connection tightened and aging (but loved) dishwasher lives to see yet another day. Thank you! 😀 😀 😀

I had a similar problem (different model) with the pump running all the time. Also turned out that the base had water in it, so was activating the flood protection system.

Interesting thing in my case, was that the machine had been operating with something small stuck in the door, resulting in a slight leak, which must have been running down into the base! (Pity the missus didn’t tell me that it had been leaking on the floor before I came home, so I spent some time looking for a leak in the pipework under the machine before realising what must have happened!)
