Another engineer asked me to look at a Glowworm Energysaver 2 Combi 100, the boiler was fairly old, but had only been installed three years ago. Asking if I'd seen one before, I told him that I'd replaced one once, and fortunately I had kept the instruction book in my van.
The customer had been using the boiler with the front case removed as this seemed to help the boiler to work. When the boiler was in operation there was quite a strong smell of fumes, and it felt as if there was heat coming back out of the fan inlet. After the boiler had run for a couple of minutes and started to ramp down there was a loud vibrating noise that continued until the flame went out. There were no error codes displayed on the boiler.
I suggested that the noise and smell were due to poor combustion, and that the engineer should get hold of the necessary seals before carrying out a full strip down service. It may be that the combustion just needs adjusting, but due to lack of servicing it could be that the heat exchanger is partially blocked. This would explain why the boiler worked better with the casing off. In the interests of safety the boiler was disconnected from the gas supply so it could not be used before a service was carried out.
We asked in Parts Center about a some seals for the heat exchanger that may need to be replaced on the boiler during servicing and we were told that the lower seal was still available, but the upper seal only comes with the heat exchanger that cost over £500+VAT. As we were not 100% confident at being able to fix the boiler without replacing the heat exchanger and there were other parts also required to fix the boiler, the customer decide to have a replacement boiler fitted.
