Morning All,
hopefully some here has experanced this isee as its driving me mad, My seven (ish will explain) year old boiler now won't reheat the water straight after running a bath(started doing this about a month ago) , it always used to. CH fine no issues, So here goes boilers on idle start running a bath, hot water comes through boiler ignites to heat water, water at the tap starts to go cold so I turn off the hot water and the boiler also turns off. What used to happen was the boiler would then reignite to heat the cold water up, but not now it just stays of, so I remove the front cover and take out the tank sensor and the boiler ignites and warms up the water, so your thinking its the sensor, heres the best bit, I have replaced all sensors, PCB board, Heat exchanger tank (6 months ago due to a previous unconnected issue) three way valve and head (the white bit) changes DHW switch, flow switch and the expansion tank . the only bits left of the seven year old boiler is the hot water tank its self. the burner and the heat exchanger plate.
As a side issue I live in a very hard water area eg descale new keetles after a week. I have been told it's possible that the hot water tank has scaled up, but want to check on here before replacing the tank as its not the easiest thing to get to.
many thanks for your help / ideas
