My chaffoteaux britony 100se combi fails to light in CH mode?
My Chaffoteaux Britony 100se combi fails to ignite in CH mode, it works fine in HW mode!?!
When I select CH mode the 30, 40, 50, 60, 70 & 80 neons light up in sequence and then go out and nothing happens, no light stays lit to point me in the direction of the fault!?!
