I have a Siemens dishwasher and it has suddently started to get very loud from the start of the cycle. It goes through the cycle without a problem but the sound certainly implies that something is wrong.
Is it likely to be a problem with the pump? Can it carry on running like this without causing more damage?
Have looked at the brochure that came with the machine and the machine itself (which is an integrated one – ie it sits behind a kitchen cupboard door). I may be going loopy but cannot see any serial number on the book or machine. How daft is that!
