Annual Homecare check yesterday. After about 10 minutes, engineer went to boiler controls (upstairs)to get boiler to fire up. Came back to boiler in kitchen and announced that the boiler would not ignite and he had to over-ride with switch on boiler. Said that ,meant over-heating but switched on and as it ran for another 10 mins. decided it was OK. When the auto control should have come on in the evening, nothing happened. I checked the digital control upstairs and found that he had switched all controls to "off". No wonder he couldn't get the boiler to flash up.
