Potterton boiler overheat

[CRAIG WALLING]

Hi Guys.
I have a potterton statesman oil fired boiler installed in about 1997
The problem I am having is that it heats up above the thermostat on the boiler then cuts out.Then starts up again
once the stat has cooled down.It does this on heat/water demand or just water.The outlet pipe is red hot
and the inlet very touchable.I was wondering if the heat exchanger could be blocked?

could be the pump

airlocks, pump failing or blockage , need someone to check it out for you, must get quite noisy as well

The pump is less than a year old and the system was flushed at same time. The airlock sounds interesting though.

Is there a way of getting the air out?

Pumps fail, irregardless of age.

Yes: get an OFTEC man in to sort it.
