Hi i recently moved into a house which has a Worcester 24i Junior boiler.

Hot water is fine but the heating does not come on.

Upon investigation it appears that when i activate the heating the boiler fires up, fan kicks in then the fan stops and boiler ticks off and error light flashes red.

Any ideas as i am struggling to find any answers on the internet.

The boiler was serviced in January so assume all worked then.

Any solutions would be appreciated

Thanks

replace water pressure switch or may need clean up drain water from system before undo from drain point or short cut close both valves flow and return on boiler than drain boiler only
