How can I stop the pilot light on my Baxi boiler 401 from going out?

sounds like the thermocouple has gone ! This is the small "phial" on the r/hand side of the plate holding the pilot assembly,with a thin copper coiled pipe attached. They cost about £4.00 and take about 30 mins to change. But you should use a corgi installer to do the job, Good luck. Rich.

baxi 401 is a bermuda. this is not a combi boiler so does not have a pressure gauge. sounds like you need a new thermocouple.
