Hi . does this happen on heating and hot water?


Hi , is the blue light flashing either , slow flash ( normally off flashes on, or slow flash ( normally on flashes off ), or fast flash, ?

JACUSTOMER-3k8k86oy- : It s a fast flash
JACUSTOMER-3k8k86oy- : fast flash

Ok , so fast flash on blue , what about the other led ?( lockout reset )?


Ok , just reread your description , if you are having fastv flashing on both red and blue this indicates a control board fault , and this will need replacing


To make sure of getting the correct one you will need the boiler GC number. Usually on a sticker , either on top of the boiler or within the casing
