i ve got a baxi 105e (3 years old / central heating system was also installed 3 years ago)
the problem is that when having a shower the water is hot then suddenly will go cold for about 30 sec, before warming up again (this can sometimes happen 2 / 3 times during a 10 min shower) temp control on boiler is set to 2/3 of max temp. the central heating works fine
the boiler is current covered via domestic general, who the last two weeks have been out twice to it. the first time the engineer said the diverter pins were corroded, and would order the parts. the second time (i was not present this time) the engineer said the diverter pins were ok, but still replaced them. he said that the problem was due to a dirty heat exchanger, (and he removed and cleaned it) his advise was to flush the system, add desludger, flush and add inhibitor.
since then i have flushed the system (and to be honest the water was resonble clear (compaired to to other systems i seen) i.e. still transpartent. i aslo added the desludger (and am letting the system run for 1 week). i did this on thursday (now sunday) and conserding the system has had a refill the problem still ocurrs (i know i only 1/4 the way through flushing)
does anybody think that this is the problem, or could it be somthing else (just read the manual - could it be the saftey thermostat?)
