Waste King, Whirlaway and Moen disposals (Anaheim-built): quick sheet

Covers: Continuous-feed disposals from Anaheim Manufacturing (a Moen subsidiary): Waste King Legend / Pro / Custom, Whirlaway, and Moen GX / GX Pro series. Mount type (EZ Mount vs 3-bolt) and motor speed vary by model; read the label.

Single sourceBrands: Waste King, Whirlaway, Moen7 components

These units differ from InSinkErator mainly in the motor: most use a high-speed permanent-magnet DC motor (Moen calls it Vortex) that reaches full speed almost instantly. Many models have no hex socket on the bottom, so jams are freed from above with a jam wrench on the turntable. Two mounting systems exist and are not interchangeable with InSinkErator's Quick Lock without changing the sink flange.

Safety first

  • Never put a hand in the chamber
  • Unplug or kill the breaker before freeing a jam
  • Confirm power off before opening the electrical cover

How it works

A permanent-magnet motor spins the turntable much faster than an induction disposal: Moen lists 2700 RPM for the GX75C and about 2800 RPM for 1 HP GX models; Waste King lists about 2600 RPM for the Legend 2600. Fast start-up is marketed as reducing jams.

Grinding works the same way as other disposals: swivel lugs throw food against a grind ring. GX models use stainless grind components.

Waste King EZ Mount is a plastic twist-on mount with a removable splash guard and about a 3-1/8 in drain opening. The Pro 3-bolt mount is stainless with a built-in splash guard and about a 3-3/8 in opening. Whirlaway Pro and Waste King Custom keep the 3-bolt mount.

Most residential units ship with an attached cord (Waste King notes Whirlaway 191 and 291 as exceptions) and may be hardwired without voiding the warranty. A red manual reset protects the motor.

Diagnostic guides for this appliance

Guide · Garbage Disposal

Disposal sink-top air switch (push button) not working

An air switch sends a puff of air down a small tube to a power module under the sink, which toggles the outlet the disposal plugs into. Check the disposal itself first, then the tube, the button and the module. Some InSinkErator single-outlet SinkTop Switch modules (2005-2017) were recalled for water entry and overheating.

Garbage disposal hums but won't turn (jammed)

A humming disposal almost always has a jammed turntable: a hard object or packed waste is stopping the motor. Free the plate with the hex wrench from below (or a wrench on the impellers from above), clear the debris, then reset the overload. Never put a hand in the grinding chamber.

Guide · Garbage Disposal

Garbage disposal dead: no hum, no power

Work from the simplest cause: the motor overload (red reset), then the breaker and outlet, then the switch type (wall switch, air switch, batch-feed stopper switch). Replace the disposal only after power is proven at the outlet and the reset does nothing.
