1) Boiler make / model (gas or oil)
ideal Response 80
2) What is / is not happening.
when the hot water tap is on the system starts for up as normal it heats the water for 10 secs then the LED 2 lockout lights up water goes cold .
putting the CH on produces the same fault.
I checked the water pressure switch it is closed circuit between term 1 & 3
the water pressure gauge reads 1.5 bar
3) Has ANYTHING else been done or changed recently.
4) When did the problem start?
today
5) When does it happen? eg, heating coming on or going off.
Heating going on
6) Anything else you feel may be of relevance.
Any thoughts appreciated , further tests etc
thanks
