Miele Reduced Grinding Efficiency

Disposal takes much longer than usual to grind food waste; performance feels weak.

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

Dulled grinding components, Worn impellers, Low motor torque due to failing capacitor, Build-up on grinding surfaces

Safety first: Turn off power at the breaker before any internal inspection.

Clean buildup: Use ice cubes and a small amount of rock salt to help remove scale and buildup from grinding surfaces.
Avoid overloading: Feed smaller amounts of waste at a time with plenty of cold water.
Inspect impellers: With power off, check that impellers move freely and are not excessively worn.
Component wear: If performance remains poor, the grinding plate or motor may be worn and require replacement of the grinding assembly or entire unit.
