Looking for technical help with my oil fired boiler.
It's a Worcester Danesmoor 20/25, more than 10 years old, which is getting increasingly hard to fire up. It runs fine once it's going, but trying to start it up either from cold or after it's switched off thermostatically results in lockout. If, after resetting lockout, I flick the temperature control on and off quickly it eventually fires, this used to take 5-10 'flicks' but now it's more like 25.
Bleeding the pump doesn't seem to have any bearing on the problem, and I have also changed the control box on the burner but that didn't help either. Fuel supply seems to be ok, I've changed the tank during all this so new heating oil and new filter. One heating engineer who I called out said it needed a new electric eye, but how can that be when it runs ok after firing?
Any advice gratefully received!
