5-2. Steam Heater
1. Function
1) It heats the water inside the AG for steam injection.
2. Precautions
1) The heater should not be exposed to air (factors such as tilting and vibration should
be considered to see if the heater is exposed to air).
2) Do not use the heater that was detached from the AG. Otherwise, water may leak.
3. Potential Failures
1) The heater does not work: When the heater is exposed to air, the heater may overheat,
causing disconnection. If the water quality is bad, foreign substances such as lime
may stick to the surface of the heater, which may lead to overheating and damage the
heater.
2) Heater overheats: If the water level sensor reads incorrect values under the high volt-
age condition, the thermistor may be damaged and lead to overheating of the heater.
4. Things to Check in Case of Failure
1) Check the Precautions section first.
2) If the heater does not work, check if there is disconnection in the heater or if the
thermistor is not faulty (check its exterior as well as its properties). Also, check the re-
sistance between heater terminals.
3) If the heater overheats, check if the thermistor is not faulty (check its exterior as well
as its properties). Also check the resistance between heater terminals.
※ The resistance should be 29.5 Ω ± 7 %.
