HI there
We have a cambray 5 bolider, which is 5 years old and get serviced every year, it is now staying on all the time and not going of with the timer or thermo switch.

thanks, spoke to my plumber who thinks one off the valves is not working thats why it not responding to switching off to thermostat or the timer switch

ok this one has really tested me! The timer is kaput/broken/faulty/ of no further estimable use, Thermo switch, I will have a guess at this one, maybe a thermostat ? If so it vindicates that the timer is US, the thermostat links through the timer, Sorry its obvious, get an expert in, don't play around with things you don't know about.
