Common questions
Which water filter fits the Breville BES870?
The Breville BES870 takes the Breville BWF100 Water Filter (part BWF100). Compatible filters made to the same specification also fit.
How often should I replace the water filter in my Breville BES870?
Every 2 months. Flow slows and performance drops off as the filter fills up, so it's worth doing on time.
Where can I buy the BWF100 in Australia?
We track 6 Australian sellers for the BWF100; the lowest listed price when we last checked was A$1.83 at Bunnings. Prices are re-checked daily and dated on this page.
How do I fit the BWF100 in a Breville BES870?
No tools, a few minutes: 4 steps, listed on this page with the replacement video where the maker has one.
What happens if I don't change it?
The filter stops softening the water, scale builds in the boiler, and the machine asks to be descaled more often; taste in the cup drops off too.
How do I reset the reminder?
Set the date dial on the filter holder handle to two months ahead when you fit a new cartridge; there is no electronic reminder on these machines. Follow the Breville AU video for soaking and fitting.
