Fires up as normal and runs for maybe 3 or 4 minutes then cuts out. Stays off for a few minutes and same again, going round in circles never getting the heating system properly warmed up!
Heating system is free of air and the pump is working!
Paul...thanks for the response.....system has been emptied and flushed, a bit black in parts but had Fernox in the system. I am confident the pump is ok and the system not blocked and no air in it. It's driving me mad!!

check the heating flow and return pies from the boiler. if the flow is getting red hot then the pump could still be faulty or the system is probably blocked
