I think I understand what I need to do but thought I’d solicit some reassurance from those more knowledgeable than me.
Come January I’ll have had my Bianca for a year. I run it on 50/50 Ashbeck and Volvic. I make 3 flat whites a week on average so Service boiler is on 3 times. I empty the service boiler monthly by switching machine off and filling a container from the HW tap until no more comes out. I then repeat the process.
I plan to descale the Service boiler come January, my understanding is I use the process above but prior to rinsing the water through the boiler I will have put some descaler in the water tank. I’ll then empty the tank and allow it to refill with the descale solution.
Repeat the above 3 or 4 times until I’m happy that all of the descaler has been rinsed though and I’m back to clean fresh water both in the tank and Service Boiler.
Does that sound ok ?
