Hi we have a Siemens integrated dishwasher and we keep getting the E15 error code and the machine is making a pumping noise. This only occurs when we use the higher temperatures together with the intensive wash button. The engineer came out and looked at the machine a couple of weeks ago and couldn’t find anything wrong, there was no water in the bottom of the machine or underneath, and none of the pipes were blocked so he put it all back and ran a rinse cycle which ran fine.
I used the machine on intensive last night and the fault has returned again. Does anyone have any ideas what may be wrong? The engineer said he will come tomorrow afternoon to have another look.
Many thanks
Karen
