Ideal W2000 No Hot Water

Was called by a customer as their hot water was not hot. They found it was cold, so put the programmer on for an extra hour only to hear a screaming noise coming from the airing cupboard after a short while. They turned it off and called me to have a look.

I put the hot water on and the boiler fired up straight away, so I went to have a look at the pump after turning the boiler thermostat off. The pump was running although it was a little noisy due to there not being enough water in the system. I suspected that the cold feed may be blocked and I ventured up into the loft to find that there was no water in the feed and expansion cistern, as the ball valve had been tied up for some time.

I isolated the water to the cistern and replaced the ball valve in case it had been tied up because of a dripping overflow. I then filled up the system, including bleeding the iring cupboard and radiators. I had to stop the pump a couple of times to allow all the air to filter out as the system had air-locked slightly. I ran the hot water for a few minutes to ensure it was circulating well before running the central heating to make sure there were no more air-locks.
