Radiator goes off after 25 minutes every time the heating is set to come on

cill · Nov 18, 2013

Can someone please help? I have an Ideal Classic SE18FF boiler, Drayton Tempus 7 Electronic Programmer and a Drayton Room thermostat.

My heating is set to come on twice a day during the week and three times during weekend. When the timer starts I have noticed both hot water and heating will come on but after say 25 minutes the pilot light on the boiler goes off prematurely. Since the pilot light is off the radiators goes cold but the light on the programmer is still on indicating that the heating is on and continues to be on until it is meant to go off as per the timer.

I have tried turning the room thermostat to the highest point possible. When I turn it up it sounds as though its working but then the boiler pilot still doesn't come on.

I also have problems setting the programmer to come on during the evenings especially during weekends as the programmer will not allow me to set it past 5:50pm.

At 8:25am the boiler randomly fired up and the radiators came on until 9:am when it was meant to go off.

Could the problem be the pump?

Could be a number of things from the description, pump wouldn't be one of them though. Better off getting an engineer out to do some diagnosis.

I have had a couple of engineers round who have been able to get everything started for a while. Each time they come out I am charged- I want the situation to be resolved. The last engineer was in a hurry to get home and I don’t think he was giving the job the correct attention he felt that the problem was the fan and wanted to charge me a ridiculous amount of money to have the part replaced. He got the heat working by using the maintenance spray it worked for only a couple of hours.
