DIAGNOSE:
1. Check if the humidity sen-
sor is functional.
Check if there is lint obstruct-
ing the sensor.
2. Check if the humidity sen-
sor is functional.
If the wiring of the sensor is
broken, repair the wiring.
3. Check if the humidity sen-
sor is functional.
If the sensor is not functional
at all, replace the sensor. (If
you blow with your mouth on
the sensor, the humidity value
must change.) (Remove filter
cap first.)
4. Check if the heating-drying
system is functional.
If there is not sufficient air-
flow or heating power, the fab-
rics in the dryer will not get
dry. Repair the problem.
5. Check if the analog input
and power supply of the sensor
on the control board is func-
tional.
If the sensor control circuit is
not functional, replace the con-
trol board.
Failure 28: Lint Filter
Failure 28 occurs when the Lint Filter Door has not been opened
for 40 succeeding cycles.
Check value of the Lint Filter Door Cycle Counter at the Running
State-Service menu. (Special function button)
DIAGNOSE:
1. The Lint Filter must be
cleaned every day.
If the Lint Filter has not been
cleaned for 40 days, open the
Lint Door and clean the Filter.
Close the door again. The Lint
Filter Door Cycle will be reset.
2. Check if the Lint Filter
Door Cycle Counter is reset by
opening the Lint Door.
If the Lint Filter Door Switch
is broken, replace the Lint Fil-
ter Door Switch. (Normal
Closed Contact.)
3. Check if the Lint Filter
Door Cycle Counter is reset by
opening the Lint Door.
If the wiring is broken, repair
the wiring.
4. Check if the Lint Filter
Door Cycle Counter is reset by
opening the Lint Door.
If the input of the control
board is not correctly function-
ing, replace the control board.
Failure 29: Timeout Cooldown
Failure 29 occurs when the Cooldown temperature is not reached
in max. allowed time (120 minutes) (Temperature selected at
Cooldown sequence)
A skilled and experienced technician must examine the heating
and air outlet system before the machine is put in operation again.
DIAGNOSE:
1. Check the air outlet system. If the air flow is not sufficient,
adjust the air outlet system.
2. Check the temperature sen-
sor.
If the temperature sensor is not
measuring correctly, replace
the temperature sensor.
3. Check the heating system.
If the heating system is bro-
ken, repair or replace the heat-
ing system.
4. Check the heating contactor
(valve)
If the heating contactor (valve)
is not functional repair or re-
place the component.
5. Check the wiring.
If the wiring is damaged, re-
pair the wiring.
6. Check the output relay that
controls the heating system.
If the output relay is not func-
tional, replace the control
board.
7. Check the input Signal by
monitoring the state at the
Service menu.
If the input is not functional
anymore, replace the control
board.
Failure 35: Wrong Software Version
When a total new software that isn't downward compatible with
previous software versions is loaded, then the software will detect
that the old and new softwares are not compatible.You have to re-
configure the FLEX CONTROL Dryer Computer. Refer to Initi-
alizing the machine.
WARNING
ALL THE CUSTOM SETTINGS WILL BE ERASED IN
THE CONTROL DRYER COMPUTER BY LOADING
THE FACTORY SETTINGS.
C142
After reinitialization of the FLEX CONTROL Dryer Computer,
fault 35 can only be erased by switching the power Off/On.
Failure 37: Too Hot Safety
Failure 37 occurs when the actual heating temperature rises
above safety temperature 185°F [85°C] while the machine is run-
ning.
If at the end of the drying cycle, the temperature is above 185°F
[85°C] ( (*) 212°F [100°C]), the dryer will go on with the cool
down sequence for 30 minutes (or until temperature below 149°F
[65°C] or until open door).
The display will show “Hot“, indicating something is wrong.
Check Safety Thermostats ST1 & ST2 as they should switch off
the heating system and prevent high temperatures.
