AEG Grinder Electrical Failure

Grinder does not run at all; machine may still attempt to brew and produce only hot water.

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

Burnt grinder motor, Faulty grinder triac or relay on PCB, Loose grinder connector, Jammed grinder causing overload

Safety: Unplug the machine before testing.

Check for jams: Empty the hopper and inspect for blockages. Try to rotate the grinder shaft gently (if accessible).
Inspect wiring: Open the housing and verify the grinder motor connector is secure on the PCB and motor.
Test motor: Measure resistance across the grinder motor terminals. An open circuit indicates a failed motor that must be replaced.
PCB check: If the motor tests good, the control triac/relay on the PCB may be defective and the board may require replacement.
