I have no hot water or heating even though the boiler fires up and the pump is turning. The motorised valve is only about one year old. Water comes out the rads when i open the bleed valves. When the boiler fires up, after about 15 seconds it starts to rumble and then cuts out. After a minute it will fire up again but cut out almost immediately. The pipe above and below the pump gets hot. Any help appreciated.
