Symptom and Trouble cause
5.2.1.
Hot water is not boiled.
Q-1 When "ON" does power switch, the power indicator lamp turns on.
→ Check the conduction of the main body unit. : Conduction less / heater disconnection is thought about.
→ Heater disconnection : Exchange of the main body unit.
→ Heater disconnection : Exchange of the main body unit.
Q-2 Even if "ON" does power switch, the power indicator lamp does not turn on.
→ Check the conduction of power supply cord, the main body unit : Conduction less
/Disconnection of the temperature fuse, defectiveness of the power switch, disconnection of the power supply cord and the main
body and the contact defectiveness of the joint of the power base are thought about.
→ Poor temperature fuse, power switch, the main body and the contact of the joint of the power base : Exchange of the main
body unit.
→ Poor in power supply cord disconnection and the main body and the contact of the joint of the power base. : Exchange of the
power base.
/Disconnection of the temperature fuse, defectiveness of the power switch, disconnection of the power supply cord and the main
body and the contact defectiveness of the joint of the power base are thought about.
→ Poor temperature fuse, power switch, the main body and the contact of the joint of the power base : Exchange of the main
body unit.
→ Poor in power supply cord disconnection and the main body and the contact of the joint of the power base. : Exchange of the
power base.
5.2.2.
Power indicator lamp does not turn on.
Q-1 Even if "ON" does power switch, the power indicator lamp does not turn on. (Hot water is boiled.)
→ Check the conduction of the main body. : Power switch is "OFF", but there is conduction. /Short circuit of the power switch is
thought about.
→ Poor power switch : Exchange of the main body unit.
thought about.
→ Poor power switch : Exchange of the main body unit.
5.2.3.
Even if hot water is boiled, it is not cut off.
Q-1 Even if "ON" does power switch, the power indicator lamp does not turn on. (Hot water is boiled.)
→ The power indicator lamp that power switch does not become "OFF" turns on.
→ Poor power indicator lamp : Exchange of the main body unit.
→ Poor power indicator lamp : Exchange of the main body unit.
5.2.4.
Hot water is not sometimes boiled.
Q-1 It is not sometimes heated with time when hot water is boiled in a state of power switch "ON".
→ With power switch as "ON", Check conduction while investing the main body on the power bade in right and left: Poor contact
of the joint of the power base is regarded as the main body unit.
→ The defectiveness of the joint of the main body and the power base: Exchange of the main body or the power base.
of the joint of the power base is regarded as the main body unit.
→ The defectiveness of the joint of the main body and the power base: Exchange of the main body or the power base.
Q-2 When hot water is boiled in power switch "ON", it is not sometimes heated.
→ Twist power supply cord and, with power switch as "ON", check conduction: When poor conduction is sometimes caused,
poor power supply cord is thought about.
→ Defectiveness of the power supply cord: Exchange of the power base.
poor power supply cord is thought about.
→ Defectiveness of the power supply cord: Exchange of the power base.
