F01

Main relay failure


Potential causes

  • Main relay defective, replace control board

  • Short circuit between heating element and ground


image



F02

EEPROM failure


Potential causes

  • Disturbance in the EEPROM re-program with SAM


image



F03

System failure


Potential causes

  • Check humidity sensor and the respective wiring and connections

  • Disturbance in control boaro


image



F04

Heater relay failure


Potential causes

  • Defective heater relay(s), before replacing the timer carry out the reset procedure

  • Grounding isaue on heating element

  • Open thermostat on heating element

F05

NTC 1 (air channel) failure


Potential causes

  • NTC 1 out of tolerance, shortage or open circuit

  • Electrical connection between NTC 1 and control unit

  • Ambient Temperature is out of dryer specification

  • Reset procedure needed if shortage was cause (refer to bottom)


image



F06

NTC 2 (heater) failure


Potential causes

  • NTC 2 out of tolerance, shortage or open circuit

  • Electrical connection between N”C 2 and control unit

  • Ambient Temperature is out of dryer specification

  • Reset procedure needed if shortage was cause (refer to bottom)

F07

Drum sensor failure


Potential causes

  • Drum sensor defective

  • Magnet not in correct position or missing

  • Electrical connection between reed switch and control board

  • Drum doesn’t turn

  • Carry out reset procedure (refer to bottom)


F10

MCU communication error


Potential causes

  • Electrical connection between MCU and control board

  • Communication error between MCU and con1roI board


F1 1


MCU motor failure:


-3' Reserved not supported


F12

MCU not initialised


Potential causes

  • MCU initialised not correctly

  • Switch appliance off and again on

  • Wrong Software on CCU, re—program ,hex file



F14


MCU failure / low voltage detection


Potential causes

  • Low voltage detection on communication bus MCU,’”CCU


F15

MCU failure


Potential causes

  • Hardware failure on MCU

  • MCU software looses control on rotor position.(locked condition)


F18

MCU failure / MCU over temperature


Potential causes

  • Temperature of the MCU ( power module IC )is too high

  • Motor cannot be started for more than 20 s


F19


MCU failure / over voltage detection


Potential causes

  • High voltage detection on communication bus


F20


Motor overheating:


-9' Reserved not supported


F21

UI communication error


Potential causes

  • Communication between control board and user interface not possible

  • Disturbance in cDnnection of control board and user interface


F22


MCU over current detection


Potential causes

  • Current limiter on MCU detect over current, overload of motor


”o carry out the reset procedure the following sequence must be performed within 10 sec..


a) Turn selector in 6 o’clock position (down)

  1. Push "start" button three times

  2. Turn selector clockwise one position (airing program)

  3. Push "start" button three times
