dishwasher pressure valve not activating
« on: September 01, 2013, 06:48:16 AM »
Our Bosch dishwasher approx 5 years old hasn't been cleaning well, so after reading up I've cleaned out some internal hoses and the pressure chamber.

as you can see it was pretty manky



However it's all clean now, but the the pressure switch which is generated from the yellow disc, which then pushes the blue lever nevers seems to trigger, the red float valve is bobbing up and down and seemingly turning water on/off and the machine is filling ok.

If I manually move the blue lever it triggers the cycle to start and the cleaning heads spin etc, but once again the cycle never ends as it appears the pressure switch isn't activating.

I've removed the whole yellow piece and blown down it and that does trigger the necessary movements which would move the blue lever.

So I'm at a loss as to what to do next!!

Cheers,

Greg
