Installation Guide
Before You Begin
- Ensure the washing machine is unplugged and the water supply is turned off.
- Gather necessary tools, which may include screwdrivers, pliers, a bucket, and towels.
- Consult your specific washing machine's service manual for detailed instructions on accessing the drain pump. Access methods vary by model.
Step-by-Step Installation
- Access the Pump: Depending on your washer model, you may need to remove the front panel, rear panel, or tilt the machine back to access the drain pump.
- Drain Residual Water: Place a shallow pan or towels under the pump area to catch any remaining water from the hoses.
- Disconnect Hoses: Carefully disconnect the inlet and outlet hoses from the old drain pump. Note their positions for correct reattachment.
- Disconnect Wiring: Unplug the electrical connector(s) from the old pump.
- Remove Old Pump: Unmount the old drain pump from its housing or bracket. This may involve removing screws or releasing clips.
- Install New Pump: Position the Supco LP1600 drain pump in the same location and secure it using the original mounting hardware.
- Reconnect Hoses and Wiring: Attach the inlet and outlet hoses securely to the new pump. Reconnect the electrical connector(s). Ensure all connections are tight to prevent leaks and ensure proper electrical contact.
- Reassemble Washer: Reattach any panels or components that were removed to access the pump.
- Test Operation: Restore water supply and plug in the washing machine. Run a short drain or rinse/spin cycle to check for proper drainage and leaks.

Operation
The Supco LP1600 drain pump operates automatically as an integral part of your washing machine's cycle. When the washer's control board initiates a drain or spin cycle, it sends an electrical signal to the pump. The pump then activates, using its impeller to force water out of the washer tub and through the drain hose, effectively removing wastewater from the appliance.
Maintenance
Regular maintenance can help extend the life of your drain pump and prevent common issues:
- Check for Blockages: Periodically inspect the drain pump filter (if accessible on your washer model) and the pump's impeller area for lint, small objects, or debris that could impede water flow.
- Inspect Hoses: Check the drain hoses for kinks, cracks, or blockages that could restrict water flow.
- Avoid Overloading: Overloading the washing machine can put undue stress on the drain system, including the pump.
Troubleshooting Common Issues
If your washing machine is experiencing drainage problems, the drain pump may be a factor. Use the table below for common symptoms and potential solutions:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Washer not draining at all. | Clogged drain pump or hose, faulty drain pump, electrical issue. | Check for clogs in the pump and hoses. Verify electrical connection to the pump. If no clogs, the pump may need replacement. |
| Washer drains slowly. | Partial clog in pump or hose, weak drain pump. | Clear any partial blockages. If the issue persists, the pump may be weakening and require replacement. |
| Loud noise during drain cycle. | Debris in the pump impeller, worn pump bearings. | Disconnect power and inspect the pump impeller for foreign objects. If no debris, the pump may be failing and require replacement. |
| Water leaking from pump area. | Loose hose connections, cracked pump housing, worn seals. | Check and tighten all hose clamps. Inspect the pump housing for cracks. If seals are worn, the pump may need replacement. |
