On an Ideal Response 120 combi, does anyone know what a flashing
"Central Heating" LED (behind the cosmetic cover) means? The symptoms
are the boiler won't light if the CH is on though the pump pumps the CH
water OK and the DHW works.


THE stock fault for this boiler is a leaking heat exchanger.
The usual presenting symptoms are that the boiler won't light because the
ignition is wet.

Thanks for the reply. The boiler lights OK when it's DHW, and the CH
doesn't get hot even when the DHW is running. I'm sure the pump's OK as
when I switch off the DHW there's a couple of seconds surge of hot in
the CH.
