Potterton Flamingo No Heating Downstairs

I received a call from a customer today that was worried about her heating. The radiators upstairs appeared to be working fine, but there was no heat at any of the radiators downstairs. It didn't matter that she turned the room thermostat right up they were not getting hot and when the boiler did come on it was only for a short period.

The programmer was set to constant for both heating and hot water, and the room thermostat was turned up high enough that the central heating should be on. Checking up in the airing cupboard the hot water was up to temperature and the motorised valve had moved over fully to the central heating position. The pump was also running although it didn't quite sound right. I thought that the cold feed may have been blocked but I felt the feed and vent and they both felt hot quite a way above where they tee in.

Pausing the rotation of the pump by moving the speed selector switch to a position between speeds didn't cause any gurgling which would suggest air or a lack of water preventing circulation. I also checked that the pump valves were both fully open. As everything seemed to be as it should I assumed that the pump was not spinning at the required velocity even though it did not look that old. I replaced the pump and switched the system back on and soon enough the radiators downstairs began to get warm.
