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
/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.
→ 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.
/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.
→ 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.
