DIAGNOSE:
1. Check if the ventilator is functional. If the ventilator is not functional, repair or replace the
ventilator, belt, motor control system, wiring or the
power supply circuit of the ventilator.
In normal operation, the Ventilator is switched On
immediately after pressing the START button.
The ventilator must stay on for the complete time of
the drying cycle.
2. Check if there is sufficient air flow.
Check if the Dryer is a closed box.
(Lint filter Door, mechanical panels must be
present and closed properly)
When the Dryer is not a closed box, air will escape
and the air flow will not be sufficient to switch the Air
Flow Switch.
Make sure that there is no loss of Air Flow.
Example : close the Lint Filter Door properly.
3. Check if the switch and metal plate and air
flow detection system is still functional.
If the air flow detection system or it's switch is out of
order, it must be repaired or replaced.
4. Check the continuity of the wiring If the wiring is not continuous : repair the wiring
5. Check the input signal by monitoring the
state at the Service menu.
If the input is not functional anymore, replace the
electronic card.
 FAILURE 9: AIR FLOW SWITCH OPEN AFTER STARTUP
Failure 9 occurs when there is not sufficient air flow when the ventilator is turning. This security function
makes that the heating is switched Off when the ventilator is suddenly Not functional anymore or if the
airflow gets obstructed.
(Failure 9 occurs only after startup) (NO contact)
The Air Flow Switch has a safety function and it’s function must not be obstructed.
A skilled and experienced technician must examine the dryer system before the machine is put in operation
again.

 FAILURE 10: AIR FLOW SWITCH CLOSED
Failure 10 occurs at the start of the drying cycle. Before the ventilator is switched On, the Air flow switch
must be open. If the flow detection system is out of order and the switch is closed, an error message will be
displayed.
(Failure 10 occurs only in standby mode) (NO contact)
The Air Flow Switch has a safety function and it’s function must not be obstructed.
