Cause
Check Method and Remedy
Power light (LED 1)
( The hand dryer does not
operate, and the light
does not light up.)
Connector discon-
nection
Check if the lead wire connectors between the power circuit board
and the control circuit board are disconnected.
Blowout of the cur-
rent fuse
Measure the resistance across the current fuses (FUSE 1 and 2)
on the power circuit board. If the resistance is not normal, replace
the power circuit board.

Malfunction of the
control circuit board
If the error persists after performing the above, replace the control
circuit board.
Malfunction of the
power circuit board
If the error persists after replacing the control circuit board, re-
place the power circuit board.
Power light (LED 1)
( The hand dryer oper-
ates, but the light does
not light up.)
Malfunction of the
control circuit board
Check if the connector CN201 on the control circuit board or
CN100 on the power circuit board is disconnected.
( If a light-emitting device of the control circuit board is in a state of
short circuit or open fault, the light does not light up.)
Malfunction of the
control circuit board
If the error persists after performing the above, replace the control
circuit board.
Power light (LED 1)
(Tamper-resistant timer)
30 seconds have
elapsed.
If hands are inserted in the hand drying area for 30 seconds, the
error occurs.
It returns to normal if hands are pulled out.
Dirty sensor window Check for dirt sticking to the sensor area.
If the hand dryer operates for 30 seconds because of dirt on the
sensor window, remove the sensor dirt, and then reset the power.
Malfunction of the
control circuit board
If the error persists after performing the above, replace the control
circuit board.
Power light (LED 1)
2 blinks
(Power failure)
Connector discon-
nection
Check if the lead wire connectors between the power circuit board
and the control circuit board are disconnected.
Malfunction of the
control circuit board
Replace the control circuit board.
Malfunction of the
power circuit board
Replace the power circuit board.
Power supply noise If there is power supply noise, use a noise filter for the power line
or take other noise-control measures.
Troubles with error display
Is the connector on the control
circuit board or the one on the
power circuit board securely con-
nected?
