Ideal logic plus 30 overheating?

[macka3]

Hi just wondering if anyone can shed any light on an issue i'm having with my boiler..

Initially started i think after i came back of holiday and the pressure was low on my boiler after topping up everything was fine and boiler operated as normal. A day or so after however i started noticing that my boiler was cutting out before the thermostat reached room temperature. It then keeps on coming on and cutting out continually every 2-3 mins before room temp is reached. I have bled all radiators and all of them heat up fine. No issue with hot water this runs fine.

note I also changed the thermostat and receiver as initially thought it was this but its still doing the same thing. It’s very annoying hearing it fire up over and over again constantly.

Any advice is much appreciated

Thanks

Have a look at your pump.

Did you close another valve while topping up?
