Gas supply to boiler shuts off randomly. No heating or hot water, pump still runs. If I switch the boiler off and on again the boiler works, heating and hot water on. May run for a week with no problem.
probably your ignition box is faulty and will be intermittent until it completely fails(especially if an older version of this boiler model- all blue box)
