Hot water problems with Baxi Combi 105e boiler.?
Question:I keep losing hot water when taking a shower or running a tap and was wondering if anyone had any ideas on what the problem is?
Sometimes it will be fine and the water will stay at the required temperature but more often than not it loses the hot water every 20 seconds are so then returns for a short burst of hot water. I have noticed that when the shower is operating without problems the water pressure is a lot higher than when it is misbehaving, does this indicate a boiler issue or something else?
Answers:
Call baxi they have a fixed fee for repair, It covers every part exept the heat exchanger & pressure vessel, Good value.
it could be an air lock in the system it will come out eventualy
Sounds like the hot water diaphragm needs replacing or the hot water thermistor. Could also be debris in the heat exchanger. Probable not a job you could tackle yourself.
It could signify a problem with the expansion vessel.
