Hi All

Got an issue with the hot water. Set it at low yet it still gose upto 60 degress on the display and actual.

Anyone know what readings i should get off the DHW sensor or anyone had the same issue

Thanks

Its either going to be a blockage in a part in the boiler as high temp rise can't get through heatexchanger or sensor is out of calibration,the other thing to see is make sure the flow through taps is good as so tap washers/jumpers drop =reduces flow rate boiler cuts out
Good luck with the ferrolis!!!
