McAlpine Imbalanced Rotor or Poor Mounting

Disposal causes the entire sink and worktop to vibrate excessively, even with no load.

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

Bent McAlpine impeller plate, Missing or damaged rubber mounting cushion, Loose mounting ring, Disposal not centred on sink flange

Safety first: Turn off power before adjusting the unit.

Check mounting hardware: Ensure the mounting ring is fully locked and the three mounting screws are evenly tightened.
Inspect rubber cushion: Replace the McAlpine mounting gasket if it is torn or compressed unevenly.
Check for internal imbalance: With power off, rotate the impeller plate. If it wobbles or catches, internal damage is likely.
