Vokera Combi help - no hot water

[francomanca]

Hi, have a 29C model which had its PCS replaced by an enginer due to an electrical fault. He left the DHW pre-heat function on before leaving (the amber light), if I try and turn it off (as it was before the repair), it stops the boiler from heating up water, won't even fire up. Any suggestions? Have tried to reboot this but no dice. Am pretty much a complete novice so any help would be appreciated.

You should get the engineer back.

leave the CH selector to on, turn the DHW temp selector fully anti-clockwise to the tap symbol, then back to the temp you want and the pre heat should turn off, to turn it back on again just do the exact same

Thanks, yup done that and the result is that the boiler no longer fires up, also unrelated or not but the whilst the water is kind of hot, it's not as hot as it should be. In any case, the engineer will come back tomorrow and sort it hopefully.

Sounds like he didn’t plug something back in or you have another issue.
