Hi,
I have a Bosch Worsester 230 combi boiler (gas), i reckon its about 8 years old. Over the last 4 weeks we have been experiencing the hot water from all taps in the house running cold after 20 secs, particularly annoying when in the shower.
This only happens when the CH is off, if the CH is on we get constant hot water no problem.
The boiler comes on ok when the hot tap is turned on, after about 20-30 secs all the flames just go out, if the hot tap is then turned off then on again the flames do not re-ignite. If left for 30 secs or so then the hot tap is turned on the boiler ignites ok.
No work has been carried out on the boiler recently which may of triggered the issue.
Is there anything i can try before calling out a plumber?
Hope you can help
Rob
