Combi Boiler Flame keeps goin on and off !! HELP PLEASEE :(

[bibekpd]

Hi,
The problem started recently about 2 weeks ago. I normaly turn the central heating on manually but i thought i would try the timer and set it up n it worked fine but as i turned the timer off next day and put the central heating manually the flame went on for 5 sec and went off and back on and it kept doing so i turned it off. Later on when i turned it back on flame ws normal for about 20 mins and back to turning off and on.

Due to this it takes double the time for the central heating to heat up also when you turn the hot water you only get lukewarm water.

Ive got a hermann supermicra 30SE, its a combi boiler.

Someone Please Help ME solve this problem !!!!

Thanks.

This seems to be a gas/combustion relayed problem and as such not suitable for DIY repair.

The best advice is to get a competent registered engineer to diagnose the problem.
