      *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.
