My group head won't flush when I put the lever down
If the grouphead on your ECM Synchronika won't flush when you stop brewing or when you push the brew lever down, review the following to resolve the 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.
- Remove cam and inspect for flat spots. If the cam is ground down it may not be making contact with the actuator.
