Alpha Boilers Guide

Hi Folks

I have an Alpha Combi boiler model HE25, it is 5 years old and so far it worked really fine. Yesterday however it started to give warm/luke water instead of hot water. What’s more I realized that when I open a hot tap (request hot water) boiler is also leaking. Any idea what is wrong? How it can be solved?

Best Regards

Ben

Hi Ben

This is a pretty common problem with Alpha Combi boilers. I am almost 100% sure your diverter valve got damaged and should be replaced. You will find some directions on how to replace it in the troubleshooting page here, but you should keep in mind that qualified personnel is needed to complete repairs on boilers generally.
