I've been looking around for some answer but could not find it anywhere... so hope somebody can help me.
Last week I switched on the central heating just for warming up the bathroom in the morning (for 1 hour) and since then the pump did not stop running.
I just switched off completely now because is very noisy.
The pump is a Myson CP53 and there are 2 valves as well. There's a thermostat in the living room and even after turning to the minimum temperature the pump does not stop.
The only radiator currently on is the bathroom and last Winter we did have some problems with the pump but eventually after turning the thermostat down it switched off.
Can anybody hep me?
