Just thought I would share this to try and stop unnecessary call out
costs

I have a Bosh Worcester boiler and it is just coming up to a year
old. This week the boiler has switched itself off twice. My mother
has the same boiler as does a colleague of mine and have all failed
this week.

On further inspection the condenser pipe from the boiler to outside
has frozen as all the drips have mounted up in the plastic pipe to the
drain and frozen and the boiler switches off,

A boiling kettle poured over the black pipe outside loosens all the
ice and the ice flows out of the black pipe into the drain. Just
press the boiler reset button and bingo it fires up and all is well.

Guess I will be doing that alot this winter!!! My work colleague had
the gas engineer who did the same thing and charged him £80!!

I guess British Gas will be making a small fortune for a 15 min call
out. My mothers boiler was the same, at least she has a sevice
contract!!

Just thought I would share.
