Hope someone out there can help.
Having some trouble with a Viessmann (Vitodens 100 - WB1A) in that it doesn't do HW... When demanded, it duly fires up and gives the tap symbol, but then begins to heat the CH circuit. We've come to the conclusion that it's the diverter valve and are in the process of getting a replacement actuator (stepper motor / cartidge unit) for my installer to fit.
The problem we currently have though is getting the old one out. Unfortunately the inst manual doesn't give any info. with respect to this part. There are two torx screws - one either side, but after taking these out it still doesn't want to budge. Anyone have any clues?
Thanks
