FLOW SENSOR FUNCTION
9-1 Flow sensor
This FlowSenseTM function detects the clogging or blocking of ducts.
Clogged duct vents or hoses decrease efficiency in drying cloths. Clogged vents can also cause fire.
This function alerts you to the need of cleaning the duct.
When the alarm about Duct clogging is on display of the panel, your duct vents should be cleaned by
yourself or serviceman.
Flow Sensor Function
How does the Flow sense function display the clogging of duct ?
The FlowSenseTM display consists of four bars
inside a box. The display has only three possible
displays as only three possible displays as shown
here (Also see the figure shown below):

9-2 Installation check
This feature allows you to quickly verify that the exhaust system is adequate for the normal function of the
dryer. The check takes only two minutes. The results of the check are displayed in the FlowSenseTM
display window as shown below
(Fig. 1). The dryer must be at room temperature for this test to be reliable. To perform this test, start the
machine in standby mode (power off). Press and hold both the DAMP DRY BEEP and the TEMP CONTROL
buttons together while turning on the dryer with the POWER button i.e. Press together the three buttons
DAMP DRY BEEP + TEMP CONTROL + POWER. The dryer will start and run for 2 minutes while it checks
temperatures. At the end of this short cycle, it will display the results as follows.

9-3 Troubleshooting for flow sensor dryer
1. Flow sensor bars light up
Is lint filter full?
Yes
Clean lint filter before every load
Yes
Check & clean duct.
No
Is duct clogged?
2. Flow sensor bars light up and does not disappear.
1. Flow sensor lights up 2 bars even when vents have been clean and even when the vents are off.
This is Normal. After flow sensor recheck full next cycle, flow sensor is reset.
(Flow sensor bars will disappear after dryer has operated two cycle)
2. Is flow sensor display changed from 4 bars to 2 bar after cleaning the duct.
Ductwork is slightly too long or has too many elbows.
Dryer can be used in this condition.
