    1. B000XGJ

      Immerse the water inlet with thermostat sub-assembly in water, and then gradually heat the water.

    2. Check that the valve of the water inlet with thermostat sub-assembly opens at the specified temperature.

      Standard valve opening temperature
      80 to 84°C (176 to 183°F)

      If the result is not as specified, replace the water inlet with thermostat sub-assembly.

    3. B000W9QC02
      *a Valve Lift

      Check the valve lift.

      Standard valve lift
      10 mm (0.394 in.) or more at 95°C (203°F)

      If the result is not as specified, replace the water inlet with thermostat sub-assembly.

    4. Check that the valve is fully closed when the water inlet with thermostat sub-assembly is at low temperatures (below 77°C (171°F)).

      If it is not fully closed, replace the water inlet with thermostat sub-assembly.
