ATTENTION !!!
IF THE DRYER IS EXECUTED WITH AIR HUMIDITY SENSOR, THE DRYER CAN ONLY OPERATE
CORRECTLY IF THE DUST CAP IS MOUNTED ON THE AIR HUMIDITY SENSOR.
FAILURE 27: NO HUMIDITY REDUCTION HUMIDITY CONTROL ONLY
Failure 27 occurs when the humidity value doesn’t decrease within 60 minutes when the drying sequence
is in progress. (Maximum drying time by humidity control is set default on 60 minutes.)
(See 9.2 Monitoring Humidity value)
DIAGNOSE:
1. Check if the humidity sensor is functional. Check if there is no lint that obstructs the well
functioning of the sensor.
2. Check if the humidity sensor is functional. If the wiring of the sensor is broken repair the wiring.
3. Check if the humidity sensor 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 airflow or heating power, the
fabrics in the dryer will not get dry. Repair the
problem.
5. Check if the analog input and power supply
of the sensor on the electronic card is
functional.
If the sensor control circuit is not functional, replace
the electronic card.
FAILURE 28: LINT FILTER
Failure 28 occurs when the Lint Filter Door has not been opened for 40 succeeding cycles.
Check The value of the Lint Filter Door Cycle Counter can be inspected 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 Filter 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 electronic card is not correctly
functioning, replace the electronic card.
FAILURE 30: BROKEN RELAIS EXTERNAL PAYMENT SYSTEM
Failure 30 occurs when the External payment system relais stays closed for longer then the maximum
allowed drying time (60 minutes).
Only applicable for set-up selection "EP = RL3". The dryer will run as long as the external payment system
relais is closed. As the dryer should not run longer then maximum allowed drying time, it will be stopped for
safety purposes.
DIAGNOSE:
1. Check it the right machine set-up has been
selected.
Select the right setup.
2. Check the external payment system. If the external payment system is broken,
repair the system.
3. Check the wiring. If the wiring is damaged, repair the wiring.
4. Check the electrical Input at the electronic
card.
If the input of the electronic card is not
functional anymore, replace the electronic card.
