I had a worcester bosch 35CDI combi installed just over a year ago. Had it serviced just over a month ago - no real problems.
Now, there is a rattling sound coming from the boiler. No noise from the pump. Problem is only experienced with the CH on. No noise with the HW only.
Any suggestions before I end up stumping £170 with a WB call out?
Many Thanks.
