Afternoon NSC,
The above boiler has operated faultlessly for the past 5 years.
However, I have noticed that the DHW for the past few days has not been as hot or lasted as long as previously - been using the immersion to help. Not sure on tank size as at work currently.
I have turned it off and back on again but not sure it made any difference. I did notice the display flashed " -I I- "after the reset.
The temperature display appears to read ~20°C higher than normal. E.g. 39 to 41 when at rest and cold rather than 20 normally. It also seems to read a similar amount lower when finished a DHW cycle.
Is this display for the output side of the boiler rather than the return?
Any ideas on what might be wrong?
Many thanks!!!
