(water pump function)
water shortage failure
1. The feedback pressure is
less than the water shortage
detection value (F1-09) and
lasts for a period of time (F1-
11)
2. The output current is less
than the water shortage
detection value (F1-10) and
lasts for a while (F1-11)
1. Insufficient water / water
shortage
2. Judging the level value is too
large
3. Detection time is too short
