condensing boiler popping and spitting water

[dannyst]

Hi all. I'm hoping for any advice.

I had a brand new baxi main condensing boiler fitted. All was well until we had a flood recently, which poured over the boiler fo a couple of hours. Afterwards. There was a low voltage error on the boiler. After letting the boiler dry out and resetting it, It began to work again. But i have noticed that recently when the boiler pre heats the water at times it thinks i may use it. I can hear a quick loud noise like a pop of air through the flue followed by a small amount of water that is spat out of the flue. It then performs as normal. Any ideas what may be causing this?

Thanks in advance.
Dan

Obviously a Worcester boiler!

You need to stop using the boiler and get a gas engineer in to check and safety check and make sure there's no water in combustion chamber and other parts not damage by water.
