5. Setup and Installation
Follow these steps for proper installation of your washing machine hoses:
- Step One: Check Flat Washers. Ensure that the flat rubber washers are properly seated inside the hose fittings. These washers are crucial for a watertight seal.
- Step Two: Connect Hoses to Washing Machine. Attach one end of each hose to the corresponding hot and cold water inlet valves on the back of your washing machine. Hand-tighten until snug.
- Step Three: Connect Hoses to Water Supply. Attach the other end of each hose to the hot and cold water supply valves (faucets) on your wall. Hand-tighten until snug.
- Step Four: Tighten Connections with a Wrench. Using a wrench, carefully tighten each connection an additional quarter to half turn. Do not overtighten.
- Step Five: Check for Leaks. Slowly turn on the water supply. Inspect all four connections for any signs of leaks. If a leak is detected, turn off the water, tighten the connection slightly, and recheck.

Once the hoses are securely installed and checked for leaks, your washing machine is ready for operation. The hoses will automatically supply hot and cold water to the appliance as needed during wash cycles.
7. Maintenance
To ensure the longevity and safe operation of your TT FLEX washing machine hoses:
- Regular Inspection: Periodically check the hoses for any signs of wear, such as cracks, bulges, kinks, or corrosion on the fittings. It is recommended to inspect them at least once a year.
- Replace as Needed: Hoses should be replaced every 3-5 years, or immediately if any damage is found, even if they appear to be functioning correctly.
- Turn Off Water: If you are going away for an extended period, it is advisable to turn off the water supply to the washing machine to reduce the risk of leaks.
- Cleaning: Clean the exterior of the hoses with a damp cloth if necessary. Do not use harsh chemicals or abrasive cleaners.
