    Worcester Boiler Heatslave 20/25 Not Working - Lock Out

    Hi, I have a Worcester Boiler Heatslave 20/25 that started locking out yesterday. I can reset the boiler and it works for a short period of time (seems to be getting shorter every time I reset). I've checked the water pressure and all good, any ideas on what the problem maybe? Cheers, Steven

    Thanks all - just an update - temp fixed now applied and working, thanks for everyone's input, much appreciated. I think I'll install one of the smart stats at some point but will just keep the temp fix for the time been.

    Worcester Boiler Heatslave 20/25 Hot Water Not Working

    Thanks for the help - will take a look into the replacement control panel. In the meantime is there any way of manually triggering this - I suspect not but worth asking. :)

    Cheers - I've attached a picture of the control panel and normally the light circled in red would be on. Yes, currently cold water comes out of the hot water tap when turned on.

    Thanks Ian, tried that, no luck unfortunately. There was no click when I pressed it so presume it had not tripped, any other ideas? Cheers for the help.

    Worcester Boiler Heatslave 20/25 Hot Water Not Working

    Hey there, I have a boiler (Heatslave 20/25) that had low pressure. I topped the pressure back up to 1 bar using the external filling pipe but the hot water still won't come on. Do I need to reset anything? Thanks for any help
