Hello,
We had a Worcester 19/24 cbi Domestic gas boiler, installed in 2004. The
installer (not now in business), informed us that there may be some residual
air in the system, as the boiler would go into 'Lock-out' mode every now
and again. He assured us that it would be OK and just to turn the
temperature control dial fully anti-clockwise and then back again to reset.
It has had this problem on and off now since then. Sometimes it doesn't
happen for weeks. Other times it can be 4 or 5 times a day!! No-one seems
able to offer much help so we have just learned to live with it! However, it
now seems to have developed a further fault in that whilst the boiler is on
providing heating and hot water it works for maybe 10- 15 minutes then
changes to show only the 'boiler-demand' light,on and steady, but the burner
refuses to re-ignite. Again, I have to reset via the temperature control
dial. This happens continuously, meaning we either have a very cold house
and no hot water, or I stand next to the boiler, resetting it, every time
this problem occurs!
We are currently trying, yet again, to find a competant engineer to look at
these faults but i wondered if anyone could offer any advice so we are ahead
of the game. (So to speak).
Thankyou,
DJW
