 FAILURE 13: NO HEATING
Failure 13 occurs when the heating system is not functional at start up.
(No temperature raise of 5°C in 30 minutes after start drying cycle.)
(See 9.2 Monitoring Temperature values)
A skilled and experienced technician must examine the heating-and air outlet system before the machine
is put in operation again.
DIAGNOSE:
1. Check if there is no interruption of the
electrical power, gas or steam heating
power supply
The machine will not heat when there is no energy
supply for the heating system.
Avoid interruptions of the energy supply.
2. Check if the heating system is functional. If the heating system fails to work, repair or replace
the heating system.
3. Check the heating contactor (valve) If the heating contactor (valve) is not functional repair
or replace the component.
4. Check the continuity of the wiring. If the wiring is not continuous, repair the wiring
5. Check if the temperature sensor is
functional.
If the temperature sensor is not measuring correctly,
replace the temperature sensor.
6. Check the output relay that controls the
heating system.
If the output relay is not functional, replace the
electronic card.
 FAILURE 15: TOO HOT
Failure 15 occurs when the actual heating temperature goes 15°C above the target temperature at the
drying process.
(See 9.2 Monitoring Temperature values)
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 sensor. If the temperature sensor is not measuring correctly,
replace the temperature sensor.
3. Check the heating system. If the heating system is broken, repair or replace the
heating system.
4. Check the heating contactor (valve) If the heating contactor (valve) is not functional repair
or replace the component.
5. Check the wiring. If the wiring is damaged, repair the wiring.
6. Check the output relay that controls the
heating system.
If the output relay is not functional, replace the
electronic card.
7. Check the input Signal by monitoring the
state at the Service menu.
If the input is not functional anymore, replace the
electronic card.
 FAILURE 16: COIN BLOCKING 1
Failure 16 occurs when the input for coin drop 1 is blocked for more then 5 seconds.
Case EP = ON.
Fault 16 will be displayed if the external start release signal is high for more then 10 seconds when the door
has been opened at the end of the program.
DIAGNOSE:
1. Check the well functioning of coin drop 1 If the coin drop micro contact or optocoupler is not
functioning 100%, replace the coin drop
2. Check the continuity of the wiring If the wiring is not continue : repair the wiring
