INSPECTION
PROCEDURE
1. INSPECT WATER INLET WITH THERMOSTAT SUB-ASSEMBLY
(a) Check the valve opening.
HINT:
The valve opening temperature is inscribed on the water inlet with thermostat sub-assembly.
(1) Add 15 cc (0.9 cu. in.) of water to the water inlet with thermostat sub-assembly from the inlet pipe side.

(2) Confirm that water does not flow out from the valve side of the water inlet with thermostat sub-assembly.
If water flows out from the valve side of the water inlet with thermostat sub-assembly, replace the water inlet with thermostat sub-assembly with a new one.
(3) Immerse the water inlet with thermostat sub-assembly in water that is between 92°C (198°F) and 96°C (205°F) for 5 minutes or more.
NOTICE:
-
Do not allow any water to come into contact with the connector of the water inlet with thermostat sub-assembly.
-
Make sure that the end of the inlet pipe of the water inlet with thermostat sub-assembly is not facing downward.
-
Make sure to immerse the water inlet with thermostat sub-assembly in the water as shown in the illustration.

(4) Leave the water inlet with thermostat sub-assembly at ambient temperature for 5 minutes so that the valve closes.
NOTICE:
Make sure that the end of the inlet pipe of the water inlet with thermostat sub-assembly is not facing downward.

(5) Check that the water that was added to the water inlet with thermostat sub-assembly has completely flowed out.
If the water that was added to the water inlet with thermostat sub-assembly has not completely flowed out, replace the thermostat sub-assembly with a new one.
(b) Check the resistance of the temperature sensor.
(1) Measure the resistance according to the value(s) in the table below.
