5. Installation Instructions

Safety First: Before beginning any installation, ensure the dishwasher is disconnected from the electrical power supply and the water supply is turned off at the main valve.

1. Prepare the Area: Pull the dishwasher out from its cabinet to access the rear connections. Place towels or a tray underneath to catch any residual water.
2. Disconnect Old Hose:
   • Locate the existing inlet hose connected to the water supply valve (usually under the sink or behind the dishwasher).
   • Carefully unscrew the hose from the water supply valve. Be prepared for some water to drain out.
   • Disconnect the other end of the hose from the dishwasher's water inlet. This connection might be a screw-on fitting or a quick-connect type.
3. Connect New Aquastop Hose to Dishwasher:
   • Identify the end of the new Aquastop hose that connects to the dishwasher. This is typically the end without the large Aquastop valve housing.
   • Screw this end securely onto the dishwasher's water inlet. Ensure the rubber gasket is properly seated to prevent leaks. Do not overtighten.
4. Connect Aquastop Hose to Water Supply:
   • Take the end of the Aquastop hose with the valve housing.
   • Screw this end onto the cold water supply valve. Hand-tighten first, then use a wrench for a final quarter-turn to ensure a snug, leak-free connection. Again, do not overtighten.

5. Check for Leaks:
   • Slowly turn on the main water supply valve.
   • Inspect all connections for any signs of water leakage. If leaks are present, gently tighten the connections further. If leaks persist, turn off the water supply and re-check the gaskets and connections.
6. Restore Power and Test: Once all connections are secure and leak-free, reconnect the dishwasher to the electrical power supply. Run a short wash cycle to confirm proper operation and check for any new leaks during the cycle.

Note: If you are unsure about any step, it is recommended to consult a qualified technician.

6. Operating Instructions

Once installed, the LUTH Premium Profi Parts Aquastop inlet hose operates automatically with your dishwasher. The Aquastop mechanism continuously monitors for leaks within the hose. If a leak is detected, the valve will automatically shut off the water supply to prevent flooding.

No manual intervention is required for the Aquastop function during normal operation. Simply use your dishwasher as usual.

7. Maintenance

Regular inspection of the inlet hose can help prevent potential issues:

• Visual Inspection: Periodically check the entire length of the hose for any signs of wear, cracks, kinks, bulges, or damage. Pay close attention to the connections at both ends.
• Leak Check: Occasionally check around the connections for any moisture or drips. Even small leaks can indicate a problem.
• Cleaning: If the exterior of the hose becomes dirty, wipe it clean with a damp cloth. Avoid using harsh chemicals or abrasive cleaners.
• Replacement: Hoses can degrade over time. It is generally recommended to replace dishwasher inlet hoses every 5-7 years, or sooner if any damage is observed.

8. Troubleshooting

If you encounter issues related to water supply after installing the hose, consider the following:

• No Water Supply to Dishwasher:
  • Ensure the main water supply valve is fully open.
  • Check if the Aquastop valve has tripped. If the Aquastop mechanism has detected a leak, it will prevent water flow. In this case, the hose needs to be replaced.
  • Verify that the hose is not kinked or obstructed.
• Water Leakage at Connections:
  • Turn off the water supply immediately.
  • Check if the connections are securely tightened. Do not overtighten, as this can damage the fittings.
  • Inspect the rubber gaskets within the connectors. Ensure they are properly seated and not damaged. Replace if necessary.

For issues not resolved by these steps, contact a qualified appliance technician.
