Heatslave 20/25 loss of DHW

HeatslaveOwner · 23 Sep 2023

Hi all,

I’ve replaced the automatic air vent on our Worcester Heatslave 20/25 as the previous one was leaking and we lost all pressure and the boiler stopped working. The heating seems to work fine but the hot water doesn’t. The PCB, diverter, pressure release, flow switch were all replaced earlier in the year and appear to be working fine. Any thoughts on how to fault find?

Thanks
Dave

Hi Dave,

Not sure if you're sorted on this, but you mention pressure loss, have you topped it back up?
