Single radiator not heating up

[Darren81]

I live in a 4 storey house with a combi boiler in the cellar. On the ground floor there is one radiator in the living room. On the first floor there is a radiator in the bathroom, and 2 further ones in the bedrooms. Finally, in the second floor bedroom, there is one further radiator. All radiators are working fine except for the bathroom radiator which is not getting hot at all. I have tried bleeding the radiator but it is full and the water is under pressure. The valves are fully open on the radiator. I am stumped, any suggestions are welcome!

A further problem is that my timer on the boiler keeps resetting randomly, if anyone could think of any potential causes for this it would be greatly appreciated.

Thanks

Darren

Could be a stuck TRV or possibly faulty pump....

There are no trv's fitted.
The sytem is a single circuit, closed loop system.
No wor has been caried out recently.
I will have to get back with the make of the timer. Hope this helps.
