Water dripping from under the boiler onto my kitchen top. I have dried the area with paper towels and looked with a torch to see where the leak is coming from, without success. I am reluctant to twist knobs etc as I dont know which is related to water and which to gas. The manual is useless and of no help to me. Any advice gratefully received.

It could be the condensate trap thats blocked they are usually quite accessible,thats if your boiler is modern enough to be a condensing boiler
