Baxi Bermuda no CH but HW working

[vonsworld]

Hi
My elderly Dad has been in hospital for 6 weeks and when he returned home we found the central heating from his Baxi back boiler is not working. It was fine before he went away.

When you turn on the hot water it works fine, the boiler fires up and you can hear the water and pump running, but turn on the central heating and nothing happens.

The CH room thermostat appears to be OK, you can hear it click on and off at the room temperature.

Any suggestions please, since we can't get an engineer until after Easter.

in the airing cupboard is there two electrical valves attached to pipe work by the pump , possibly 1 with 3 connections

Ensure it is enabled via the timer, to run the central heating first.

Does it have a 3-port valve, or possible two 2-port valves, to switch the heated water flow, between HW and CH? This would likely be in the airing cupboard, if you have one, where the hot water cylinder is located. These valves, sometimes stick. It might be worth giving it a sharp tap on top, with your hand, it often frees them.
