Here are a few notes on descaling the Breville 920XL (DBD).
- Start the descale program before draining the boilers. You can remove the filter from the reservoir and add the water and Dezcal solution beforehand.
- This time I’m using 1 litre of water in the water reservoir with 100 ml of Dezcal (10% of 1l or 1000 ml)
- Don’t re-install new filter until last step. I don’t know why but that is what the instructions say!
