Lelit Three-Way Valve Not Venting

Backflush water does not flow to drip tray; pressure builds but no discharge when brew stops.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Stuck or scaled three-way solenoid valve, Blocked discharge hose from valve to drip tray, Faulty solenoid coil not energizing/de-energizing correctly

Safety first: Unplug before internal work.

Backflush with detergent: Attempt several detergent backflush cycles to clear minor blockages.
Check discharge hose: Ensure the hose from the three-way valve to the drip tray is not kinked or blocked.
Inspect solenoid: Remove the solenoid coil and valve body. Clean internal parts with descaler and ensure the plunger moves freely.
Replace valve: If the valve remains stuck or the coil is burnt, replace the three-way solenoid valve.
