Hi guys.
This problem is driving me nuts. I have a Worcester high flow 400, 7 years old. For the first 5 years or so, no trouble. Since then I have had the fan, pump, temp sensor replaced. I have had the plate heat exchanger removed, cleaned through(not much crap) and refitted. Now the constant problem is the boiler cutting out via the overtemp sensor tripping. Before I call out Worcester (probably costing at least 2 limbs), any ideas? Big old house, lots of rads, all air out.
Thanks in advance!
