📹 How To Resolve Getting Poor or No Flow From the Group Head on the Bezzera BZ10

Poor Or No Flow From Group Head

This machine features programmable shot timing; please check to make sure the shots are programmed properly before doing the following steps. Shots can be accidentally programmed to zero, and as a result it may seem like there is a flow issue. Try using the manual brewing function to test for flow before proceeding. If the steam/hot water for the machine is working fine then there is likely something causing a blockage or pressure issue in the brew circuit. Otherwise refer to this machine's "No Water Flow" article.

  • If a water softener is attached to the inlet line of the machine, it may be preventing water from flowing. Please remove the softener and see if the flow improves.
  • The group head is dirty and needs to be cleaned.
  • Taking apart the group head for manual cleaning is the first step. This should be done on a monthly basis.
    • If cleaning the group head restores flow to the group head, the machine should be immediately backflushed to prevent further flow issues.

  • There might be a kinked, broken, or loose line somewhere in the machine. Remove the top of the machine and take a look inside to see if you see any obvious issues.
  • There might be an issue with one of the internal valve assemblies, which may need to be cleaned or replaced.
