Miele Intermittent Mechanical Binding

Disposal runs but occasionally stalls when processing normal food waste, then resumes when switched off and on.

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 motor bearings, Warped grinding plate, Loose impeller catching on housing, Misaligned rotor shaft

Safety warning: Disconnect power at the breaker before inspecting internal components.

Manual rotation test: Rotate the shaft via the bottom hex socket through several full turns. Feel for tight spots or scraping.
Inspect chamber: Look for signs of metal-to-metal contact or scoring inside the chamber.
Check impellers: Ensure impellers are firmly attached and not contacting the housing.
Component replacement: If binding is mechanical and repeatable, the grinding assembly or motor bearings likely need replacement.
