Possible Causes
Worn E61 group valve gaskets, Debris on valve seats, Misadjusted cam follower, Dry or worn cam lubrication
How to Fix / Troubleshooting
Safety first: Turn off and unplug the machine. Allow the group to cool before disassembly.
- Backflush first: Perform a thorough backflush with detergent to remove debris that may be preventing the valves from sealing.
- Check lever feel: Move the E61 lever up and down. If it feels rough or notchy, the cam and valves may need service.
- Service the group (intermediate): Remove the lever, cam, and valve assemblies. Inspect and replace the small valve gaskets and springs as needed. Clean the valve seats.
- Lubricate cam: Apply food-safe silicone grease to the cam surfaces and reassemble. Proper lubrication helps the valves seat fully.
