Vokera Flowmatic no hot water

Hi All

I have a Vokera boiler model called Flowmatic, it is 6 years old. Today morning I got really irritated once I realized there is no hot water, the water is hardly warm. No error message, no nothing. Has anyone an idea what is wrong? Central heating is working normally.

Best Regards

Joe

Hi Joe,

I am not an expert, but usually you get a luke water while central heating is on and working when there is an issue with a diverter valve. You will need to replace it. It is a huge work to be done, so if you are not an expert I would advice you to call for local professional as you may end up with replacing not only diverter valve but also disphragm washer, fan and burner- as it was in my case when I started to work on the boiler myself…
