As stated above, the 'water hammer' problem is experienced each time the dishwasher fills with water. That apart it works fine but the noise is really irritating.....and appears to be getting worse over time. Any ideas?

There is this part located on the left side of the machine, that has micro switches, one governed by a floating block and one by a membrane, so obviously it it meant to control fluid level and pressure.
This part was soiled. I bought a new part, but cleaned the old in order to be prepared for reoccurence of the problem.

No more water hammer here. For the moment, that is...

My answer is no answer really, but I am facing the same problem with a Bosch Logixx Auto 3 in 1 dishwasher.
I am losing sleep over this and i am even a bit worried it may damage my soldered copper tubing that is really hard to reach.

I have found similar problems on a Dutch forum, but it was about another Bosch dishwasher and the solution mentioned there was not really clear to me.
