Why do I have hot water but no central heating???

[Not a scooby]

Hello, can anyone help me.

I have an Ideal FF30 minimiser SE boiler. I am running a Horstmann HRFS1 programable timer with it. The hot water is working fine. Switched on the central heating last night and nothing.:smartass: The thermostat is working fine, the little fan sign shows it is alerting the receive, checked the receiver and the little green lights comes on saying it has received the message but nothing, boiler does not ignite. Tried putting on the hot water at the same time ignites but still no hot radiators. Have bleed the radiators but nothing to bleed, water straight out. Have been in the roof and checked the water level in the black box as this is a open vent system and all is good. Have tried powering everything off and back on but still nothing.

Any Ideas?????

Failed motorised valve?

It could be the valve that controls the heating can you send photos of controls in cylinder cupboard

I just discovered I have some heat from an upstairs radiator but no where else, so if a valve would that still happen??

Is the leaver on the grey power head moving ? if not motor could be US, remove the power head and then see if motor moves if it does then its the brass body that has sized up, If one or the other is at fault replace the complete valve

Now I a man gonna sound stupid but the little black lever yes moves but doesn't seem very connected to anything and is very wiggly?? Grey power head being the mid position valve??
