FAQ · Fellow Aiden
Why does Aiden ask to descale again?
The three phases may not have been completed close enough together. Finish the 16-, 10- and 10-minute stages and answer each refill prompt within five minutes.
Can I use powdered descaler in Aiden?
Fellow recommends a high-quality biodegradable, phosphate-free liquid coffee-machine descaler. Use the stated liquid concentration rather than improvising.
