Baxi combi 105he CH Cut out

[zakbelle]

HI my dad has a problem with his baxi combi 105he, it's been trouble free for around 7 yrs but now appears to cut out before reaching the thermostat temp. The radiators are not getting hot. In summary

1. CH thermostat requests heat, boiler comes on for around 5 mins then cuts out
2. Boiler lights show to heat up to 80c all lights are on and burner is clean.

3. Radiators are not getting hot
4. Thermostat has been tested okay
5. Pcb and CH thermistor have been replaced

Does anyone have any ideas? Local plumbers seen to have given up and others just want to replace the boiler.

Cheers in advance for any advice

Craig
