Hi,
I have a Potterton boiler that happily fires up, heats for about 2 minutes and then switches itself off.
When I put the programmer on 'Hot Water', the pump gets very hot - the pipes in and out of it are hot too, so the heated water appears to be in the tank, and presumably pumping.
What I notice is that when I turn on the 'Heating' the pipes to the Radiator do not get hot, and the boiler feels as though the thermostat is switching it off.
My feeling is that water isn't circulating, and possibly the pump is broken, if i place a screw driver on it, and my ear to the head of the screwdriver, i certainly hear rushing water, hard to ascertain whether it's actually pumping. The down pipe out of the boiler gets immensely hot, and i have to turn the boiler up to setting 4 to get it to ignite and heat for 2 mins.
There's a constant filling of water sound in the cupboard with the tank whenever hot water or heating is switched on. And the radiators did before hand make a bit of a funning crackling noise.
I hope someone more informed than me can help assist my fault isolation. Symptoms are as follows:

- Boiler heats for 2 mins only before switching off
Pump gets very hot, and so do pipes surrounding it
The actuator that switches between hot water circuit and heating does not appear to be working. I unscrewed it and turned on heating and then water, and it did not move a bit.
Help! my landlord is not returning my call, email... even if the actuator is broke, it should be divert to hot water pipes.
Appreciate any advise really.
Thanks in advance,
Lewis
