Dishwasher pressure chamber.

[David]

Hi there,

Our 6 year old Siemens integrated dishwasher broke down and today it got repaired, I came home from school and I found out that he replaced the "pressure chamber", the old one was on the worktop.

I am interested to find out what that part actually does, so could anyone explain please?

A piccy might help.

Without one my guess is it's the device that checks if the water has reached the correct fill level.

Thanks, it is exactly like this one:

guessed right! Looks very similar to one in my Neff dishwasher. The red part is actually a float. When the machine fills with water the float rises and activates a microswitch to turn the water off.

My Neff stopped washing properly and I fixed it by giving that part a good clean. It had been covered in grease and muck which caused it activate the trigger when there was too little water, which in turn lead to a very weak spray.

I'd tried dishwasher cleaner but it never touched this area of the machine.

Can't recall what the yellow bit does.

It operates the other microswitch: dishwashers need to sense both "enough water to wash" and "drained properly".

Thanks, it was filled with grease but the guy who repaired it (from Siemens I believe) just replaced it instead of cleaning it.

On the packet was written: Original pressure chamber, suitable for Neff, Bosch and Siemens.
