Baxi solo overheating

[Lex]

--------------------------------------------------------------------------------

The boiler runs and works for about 20 minute and then stops, the Overheating light comes on. I follow the procedure of switching off for 10 seconds and then turning the knob back to temperature.It then works for about 20 minute and then stops again. The thermostat has been replaced and the system cleaned out. .
Can any one fix it? Thanks Lex

Circulation problem.
Try bleeding the pump.

Thanks Bahco, will softly surjest it to the plumber when comes back in a week. I think you are right.
He put cleaning agent in for a start and will remove it next week. Lex
