Bosch Dishwasher SGV56A03GB/42 Generally the dishwasher operates

Resolved Question:

Bosch Dishwasher SGV56A03GB/42
Generally the dishwasher operates and cleans OK. However, on filling with water this occurs ok but when full the water valves appear to cycle on and off and about 1 second intervals for about 5 - 10 seconds. Sounds not right and produces knocking in mains water feed.

Hiya,
On the left side, the smaller tank.
Look carefully as this is the normal cause of the problem.
The orange float has a small hole below it that blocks.
You need this chamber out so you can take it apart and clean it out thoroughly.
There's a pipe connected to it that goes to the circulation motor.
This has to come off and be cleaned out too.

Once done properly, it cures the problem.

If you don't clean it, you need a new pressure chamber and transfer hose.

Hope this helps
Thanks
