General Operation:

1. Turn on a medium stream of cold water.

Odor Prevention:

• Regularly flush the disposal with cold water after use.
• Grind citrus peels (lemon, lime, orange) occasionally to freshen the disposal and help clean the grinding chamber.
• Avoid pouring grease or oil down the drain, as it can solidify and cause clogs and odors.

6. Troubleshooting

If your Moen GXP33C garbage disposal encounters an issue, try these common troubleshooting steps:

• Unit Not Starting: Check if the power cord is securely plugged in. Press the red reset button located on the bottom of the disposal. If the unit still doesn't start, check your circuit breaker.
• Humming but Not Grinding: This usually indicates a jam. Turn off the disposal and disconnect power. Use the provided jam-clearing wrench (or an Allen wrench) to insert into the center hole on the bottom of the disposal and turn it back and forth until the jam is cleared. Alternatively, some models allow clearing jams from the top using a specific tool. Remove any foreign objects with tongs or pliers (never your hand). Reconnect power and press the reset button if necessary.
• Leaking: Check all plumbing connections for tightness. Ensure the sink flange is properly sealed with plumber's putty.
• Excessive Noise: Ensure the disposal is securely mounted to the sink. Check for any foreign objects inside the grinding chamber.
