Hi
I have an intermittent faulty hot water sensor flashing light. Basically the DHW works fine but about 3 times a week it stops working & the faulty hot water sensor light flashes so I turn the boiler off for 10 seconds then back on and the light stops flashing and the DHW works fine again for a few days.
The hot water in the shower occasionally goes luck warm then back to hot.
I replaced the hot water sensor about 3 months ago when I descaled the heat exchanger because the shower was going hot/cold/hot cold.
Is this a faulty hot water sensor or something more? Wondering whether it's the PCB as if it was the sensor then surely this would be a permanent fault?
Has anyone come across this issue?
Thanks
Adam
