Grundig Brew Circuit Blockage

No coffee comes out of the spouts, but you can hear the pump running.

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

Clogged coffee spouts, Blocked brew group filter, Scale blockage in thermoblock outlet, Blocked three-way valve

Safety first: Unplug the machine and let it cool before disassembling any parts.

Clean coffee spouts: Remove and rinse the spout assembly. Use a fine brush to clear dried coffee.
Clean brew group: Rinse the brew group thoroughly and scrub the filter screen.
Run descaling cycle: Perform a full descaling to clear internal scale blockages.
Test hot water function: If hot water flows but coffee does not, the blockage is likely in the brew group or coffee outlet.
