Mend Ariston Micro Combi 27 MFFI Boiler Stopped Working Water

How can I fix my Ariston Micro Combi boiler that keeps cutting out?

I have a Micro Combi 27 MFFI boiler that has stopped working. On water heating it fires up normally for about 5 seconds and then cuts out. Leaving water flowing for a few minutes it fires up again for 5 seconds and cuts out. Heating circuit won't fire up at all. No warning lights come on for boiler or flue restriction. Could this be a thermal switch problem?

may be a problem with the pump.
