troubleshooting guide
Use the official Cup-One guide to diagnose a no-start, slow brew, overflowing basket, or descaling need—without guessing at error lights.
MODEL-SPECIFIC QUICK ANSWER
Technivorm Moccamaster Cup-One common problems and fixes
The Cup-One is a 10 oz drip brewer, not a coded-error machine. Moccamaster says it must detect water in the reservoir before brewing. For a slow cycle, clean the basket and descale on schedule; if water is present but brewing still will not begin, contact Moccamaster rather than opening the brewer.
