Worcester Bosch Reset Flashes Problem With Worcester Bosch 24i..............?

Problem with Worcester Bosch 24i..............? - worcester bosch reset flashes

I was in the boiler and the water again today, when I have work done in my bathroom. I have the net again and the light is on but no heat or hot water. The discussion so far has told me to press the reset button on the top of the boiler on the left side, about an inch forward. However, I have the same model, but there is no reset button on the top! All I can see is 2 things twisty knob - a brown and red with a cap on him. If a button! Please help.
