Expobar Brewtus IV: Group Head Won't Flush When Pulling the Lever Down

Troubleshoot Expobar Brewtus IV group head not flushing.

E61 Group Not Flushing

If the E61 group in your Expobar Brewtus IV isn't flushing when you pull the lever back down, it's likely not a serious issue. Move the lever up and down and see if resistance is felt in any direction from the cam moving between actuators (valves). If it will not drain, and not much resistance is felt, remove the bottom of the E61 group head and inspect the actuators. They may be broken, or ground down from poor maintenance that the cam does not make contact with the top of the actuator. They should be a squared off shape. If they are rounded down to a point, it's time to replace them.

  • Remove the cam and inspect for flat spots. If the cam is ground down it may not be making contact with the actuator.
