Hi all,
I've just replaced my grundfos pump with a new grundfos ups2 pump which is situated next to an old smc comet 2 controller. Before fitting the pump I had to drain the system down as the shut off valves either side of the pump weren't working correctly. I have now refilled the system and bled all the air ( I think ) out of the system by bleeding all the rads and bleeding the two tall pipes that are situated next to the immersion tank. I have also been up into the loft to check the small tank is full and it is. Now, the problem is when I turn the switch on the control panel to hot water only the boiler fires up and after about 2 minutes stops also when I turn the the switch to hot water & heating there is no power to the grundfos pump. Any help much appreciated!
