Operating Instructions
The InSinkErator Model 444 is a continuous feed disposer, meaning you can add food waste while it is running.
Basic Operation:
- Turn on a medium stream of cold water.
- Turn on the disposer switch.
- Scrape food waste into the sink opening.
- Allow the disposer to run until all waste is cleared and only the sound of the motor and running water is heard.
- Turn off the disposer switch.
- Let the cold water run for a few seconds to flush the drain line.
Acceptable Food Waste:
- Most fruit and vegetable scraps
- Small bones (poultry, fish)
- Coffee grounds
- Eggshells
Items to Avoid:
- Large bones, corn husks, artichokes, onion skins, banana peels (fibrous materials can jam the disposer).
- Grease or oil (can solidify and clog pipes).
- Glass, metal, plastic, rubber, fabric, or other non-food items.
- Harsh chemicals or drain cleaners.
Maintenance
Regular maintenance helps ensure the longevity and efficient operation of your disposer. The Model 444 features stainless steel grind components for enhanced durability.
Cleaning Your Disposer:
- Daily Flush: Always run cold water for a few seconds after turning off the disposer to flush out any remaining food particles.
- Deep Cleaning: Grind small pieces of ice and citrus peels (lemon, lime, orange) through the disposer. The ice helps to scour the grind chamber, and the citrus peels provide a fresh scent.
- Splash Guard: Periodically remove and clean the rubber splash guard to remove food buildup.
Do not use chemical drain cleaners in your disposer, as they can damage internal components and plumbing.
Troubleshooting
Before calling for service, review these common issues and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Disposer does not start | No power, tripped circuit breaker, or internal reset button needs pressing. | Check circuit breaker. Press the red reset button on the bottom of the disposer. Ensure power switch is on. |
| Disposer hums but does not grind | Jam in the grind chamber. | Turn off power. Insert a 1/4-inch hex wrench into the center hole on the bottom of the disposer and turn it back and forth to free the jam. Remove the object with tongs. Do NOT use hands. |
| Leaking from disposer | Loose connections, damaged seals, or internal corrosion. | Check all plumbing connections for tightness. Inspect seals for damage. If leaking persists from the bottom of the unit, professional service or replacement may be required. |
| Slow draining | Clogged drain line or buildup in the disposer. | Run cold water and disposer for longer. Clean the splash guard. If drain is still slow, the plumbing beyond the disposer may be clogged. |
If troubleshooting steps do not resolve the issue, contact customer support.
