The clean lamp is blinking (on for 4 seconds, off for 1 second).
The cleaner is not operating.
The self-diagnosis memory stores "timer lamp blinked 18 times."
Has the cleaner become mechanically locked?
Is the connector CN8 or CN10 loose or is there any lead
wire break?
Is the cleaner drive circuit normal?
※For details, see page 176.
Yes
No
Replace the "cleaner drive motor."
Is the cleaner drive motor (shaft) running?
Yes
No
Replace the "cleaner location detection switch."
Replace the "cleaner."
When the cleaner is moving rightwards, press the
cleaning location detection switch. Will the cleaner then
stop?
To perform self-diagnosis (failure detection) on the cleaner, turn off the power, ensure that the
power relay has become turned off, turn the power back on, and catch the timing at which
initialization starts.
