We have a worcester hi flow 400 about 13 years old. The hot water is very noisy and keeps over heating and cutting out constantly having to hit the reset button.
I have had various parts replaced under maintenance contract with local firm including chocked vessel hose, dhw themostat both stats replaced.
Boiler flushed out and used x400 in for 2 weeks. Worked ok for about 6 months but now when the hot water is on the boiler sounds like its gasping.
Is it worth flushing again or just replacing the boiler?
Firm says not covered under maintenance for sludge in boiler, by the way when flushed water was pretty clean
