Next time it stops working do not reboot it and get the engineer back out. you may be hiding the fault when you reboot it, I am not an engineer but i have a customer that had a problem with her boiler and she also got water out of the case, we did the work to stop this happening again by fixing her gutter (when it was raining the gutter overflower at 1 point the water went down the flue and stopped the boiler from working ) rebooting it could dry out the water in the flue so the engineer would not see the problem,

as for withholding the payment this is the wrong site for that
