Miele Bean Level Detection / Grinder Load Sensing Issue

Machine frequently displays 'Refill beans' even when hopper is full

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

Very light roast beans causing low grinder load, sensor miscalibration, blocked grinder chute, faulty grinder motor current sensing

User-level actions:

Use standard medium roast beans instead of very light or very oily beans.
Clean the grinder chute and brew unit to ensure beans are being ground and used properly.

Technical checks:

If the message persists with normal beans, the grinder load sensing on the control board may be misreading and require service diagnostics.
