Machine drips coffee or water from the spouts for a long time after brewing.

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

Worn outlet valve seals, Coffee spout partially blocked, Three-way valve not closing fully, Excessive scale in outlet path

Safety first: Allow the machine to finish its cycle and cool before cleaning the spouts.

Clean coffee spouts: Remove and rinse the spout assembly to ensure free flow.
Descale: Run a descaling cycle to improve valve sealing and flow.
Check drip tray capacity: Ensure the drip tray is in place to catch residual drips.
Service if heavy dripping: Continuous dripping may indicate worn seals in the outlet or three-way valve that need replacement.
