Group Head Not Flushing when the Brew Lever is Pushed Down
If the group head won’t flush water into the drip tray when you pull the brew lever down on your Profitec Pro 500 PID, there may be an issue with the actuator valves that trigger the drain.
- 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 so 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.
