- Prepare the Dishwasher: Disconnect the dishwasher from its electrical power source and turn off the water supply. Pull the dishwasher out from its cabinet enclosure if necessary to access the drain hose connections.
- Locate Existing Siphon Break (if applicable): Identify the current siphon break assembly or the designated location for its installation on the dishwasher's drain hose. This is typically located above the flood level of the sink or drain connection.
- Remove Old Siphon Break (if applicable): If replacing an existing siphon break, carefully disconnect the drain hoses attached to it. Be prepared for residual water to drain. Use a towel to catch any spills.
- Install New Siphon Break: Attach the Whirlpool 285320 Siphon Break Kit to the drain hose according to the orientation specified in your dishwasher's service manual. Ensure all connections are secure and free of leaks. Clamps may be required to secure the hoses.
- Reconnect Hoses: Reconnect the drain hose to the dishwasher's drain pump and to the household drain connection (e.g., sink drain or garbage disposal inlet). Ensure the drain hose forms a high loop to prevent backflow, even with the siphon break installed.
- Restore Power and Water: Once all connections are secure, restore the water supply and electrical power to the dishwasher.
- Test for Leaks: Run a short wash cycle and carefully inspect all connections around the siphon break kit for any signs of leaks.
5. Operation
The Whirlpool 285320 Siphon Break Kit operates passively as part of your dishwasher's drain system. Once correctly installed, it automatically prevents dirty water from siphoning back into the dishwasher tub by introducing an air gap. No user interaction is required for its function during normal dishwasher operation.
6. Maintenance
The siphon break kit generally requires minimal maintenance. Periodically, it is recommended to:
- Inspect for Wear: Visually inspect the siphon break and its connections for any signs of cracks, leaks, or deterioration of the plastic or rubber components.
- Check for Blockages: Ensure the air gap opening is clear of any debris or mineral buildup that could impede its function. If necessary, gently clean the opening.
- Verify Secure Connections: Confirm that all hose clamps and connections remain tight and secure.
If any damage or persistent issues are observed, replacement of the kit may be necessary.
7. Troubleshooting
| Issue | Possible Cause | Solution |

| Dishwasher not draining completely. | Siphon break clogged with debris or mineral buildup. | Inspect the siphon break for blockages and clean if necessary. Ensure the air gap is clear. |
