When open or shorted
thermistor (TH1) is detected.
After the beginning of the
drying work
When open or shorted
thermistor (TH4) is detected.
Water level detector detect
increasing of water level (
Includes foam)
Detect abnormal signal of the
Heater relay
Door lock switch won't operate
even operating position
Rotation speed of the Cooling
fan should be detected below
1200r/min
Incase breaking time shall be
measured lower than
specification.
Detect abnormal signal of
every axial amplitude.
During spinning acceleration
data shall not be obtained or
alternated.
Every 5 seconds, the data
from the warm water
thermistor is compared with
the data obtained 10 second
ago, temperature difference is
detected to be 4 degree or
above for 3 consecutive times.
Detecting the drum rotation by
rotary detector in the motor.
When the motor is started, the
input signal of rotary sensor 1
does not change beyond the
specified time. (Restart for the
second time and perform the
abnormality detection)
Measure input voltage (
Voltage is above tolerance
level)
Measure input voltage (
Voltage is below tolerance
level)
When the over current

motor has run for a total of 130
times
When compared to the 10
seconds before the TH4 data
of every 5 seconds is
abnormal.
