Alright guys?
Went to my mates boiler as he wasn't getting hot water and the radiators were warming when running the tap, so went and fitted a new diverter valve, the old one was jammed solid.
Anyway, I was rushing the job as I had somewhere to be, and ended up putting the valve in the wrong way :mad2: and when running the boiler, the display was saying d, which means that hot water is running but no taps open and diverter was in heating position. Took me ages to work out what was going on, then finally realised that the diverter was in wrong, so re-fitted correctly and it worked fine then.
Question is, how does the boiler detect dhw flow as there's no flow switch or anything? And why was it showing d on the screen when the valve was fitted the wrong way?
Any info would be appreciated.
Also, are these heat exchangers prone to leaking down condensate? He keeps losing about 0.5 bar a day, only a small system with about 5 radiators
