Hi so I have no hot water or heating with a loud humming noise in the boiler. A week ago, when you put the heating on or wanted hot water, the flame was not igniting. No flame failure light. Pressure fine. Switch it on and off and then it starts to work temporarily till it happens again.... no good ......called an engineer... says it’s working fine and he can’t guess at what part to replace .... goes away.... few days later, it breaks down completely with a really loud humming noise in the boiler. No appointment for 3 days I have young kids and a very cold house as heating been off for a week now. Rightgas Engineer will be coming on the weekend and most probably won’t have the part! Anyone wanting the job?!
