    2. Check the valve opening temperature.

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

      Check the valve lift.

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

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

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

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