The hot water supply from my Vokera 28e boiler is almost non existant. When atap is turned on the gas ignites, but extinguishes after about 15 seconds. it then ignites agin after about 45 seconds, but only for aboit 15 seconds. thison / off cycle continues.
A heating enginer replaced a rubber "grommet" which hesaid would solve the problem, but it didn't.
A second heating engineer toldme to flush the system, as the heat exchanger was clogged with "muck". I used th flushing agent he suggeted, leaving it in th system for 6 wek ( he had suggeted 4 weeks). If anything, it's now worse, wth almost no hot water.
Does anyonehave a sugestion as to th cause of my problem?
