8.7. PROBLEM CHECK LIST
Problem Cause Solving the problem
When the power is switched on :
the display is not illuminated
Remark :
The display must always light up when
the power connector is connected to
the electronic board (EPROM with
software must be implemented)
• no external power
• the emergency button is activated
• the power connector is not connected
on the board
• the power connector is inverse
connected
• the fuse on the electronic board has
burned
• disconnect the input connector
• check if the EPROM that contains the
software is implemented
• Switch on the external power supply
• verify the external power to the machine
• deactivate the emergency button
• connect the power connector
• check the wiring and connect the
connector as it must be
• if the transformer is burned replace the
electronic board
Check the wiring and the voltage at the
power Connector
If the transformer is still OK change the
Fuse
• if the display is lighting up:
verify if the input signals or the +16Vdc
Supply Signal are touching the cabinet
• if there is no EPROM implemented on
the electronic board, put the right EPROM
with software into the socket
The display is illuminated, but it’s
difficult to read the text on the display.
• the brightness is not Ok • Change the value for Brightness in the
Configuration Menu until you get a bright
display.
The machine is not starting up
• the key switch stands in “Program
mode”
• set the Key switch to “Run mode”
The machine is not responding on
pressing the keyboard buttons
• the key switch is not functional
• the “START” button is not functional
(the key switch stands in Program
mode)
• no button is functional and the key
switch is in the right position
• there is no beep signal when the
buttons are pressed
• check if the input connector “A” is well
connected and check the wiring between
the input connector and the key-switch
• set the Key switch to “Run mode”
• check if the connector “K” of the keyboard
is well connected
• check if the connector “K” of the keyboard
is well connected
The machine is not behaving as
expected
• if the wrong machine type is selected
the wrong outputs will be activated
• check if the right machine type is selected
in the Configuration Menu.
A program is started, but the outputs
are not activated
• check if connector “R” and “Q” are
connected
• check if connector “R” and “Q” are not
inverted
• connect the connector at the correct
position
• Pin “Q10” must be supplied with 220Vac
when the door is closed
Wait is displayed and a counter is
counting down
• this is a wait state caused by a power
interruption or a safety sequence at the
end of the process
• wait until the counter has reached 0
• do not switch off/on the power again as
you will restart the counter
Unload is displayed and the Door is
Open
• Check if the “Door Switch” is still
closed
• If the “Door Switch” is broken, replace the
Door Switch”
Wrong water level
(the water level sensor must not be
calibrated)
• check if the programmed water levels
are the correct ones
• check if the right machine type is
selected in the Configuration Menu
• you have changed the machine type,
but the standard water levels do not
change
• set the right water levels
• select the right machine type in the
Configuration Menu
• the standard water levels can only be
reinitialised by programming new values or
by loading the Standard Wash programs
again.
The drum is not turning
(No error message will be generated)
• Check if the belt is broken
• Check the applied motor voltage
• Check if the motor is still functional
• Check the Inverter
• Check the tension of the belt or replace
the belt
• repair the motor power supply circuit
• change the motor if needed
• send a request for more info to the
manufacturer
