Problem Check if … If not, action to do
The unit doesn’t power up
no LED light on beside the
ON/OFF switch button
plug is inside the socket plug in
circuit breaker is on re-engage
voltage arrives to the outlet problem not related to the unit
voltage arrives to the terminal block
: US version: 208V between L and N
CE version: 400V between all
phases and 230V between L3 and
replace the cable and cord
wires are hooked in the terminal
block
fi x the wires following the electrical
diagram
voltage is coming into the PCB with
a voltmeter : 208V between 121
and 122 on the connector 12 on the
board - CE version : 230V between
121 and 122 on the connector 12
on the board
reconnect or replace the cable if
damaged
the LED doesn’t work replace the board
no initial display of “init” and “UIxx” replace the board
The unit doesn’t go in preheating
On/off button is blocked (no
«click»)
membrane is in place and not
damaged
change the membrane
button is not damaged change board
position between the board and the
membrane is OK
reposition the board or the mem-
brane
No preheating mode indication
in the display
KM1 is working by visually checking
if the indicator moves from the initial
position and the power coming in
reconnect the wires or replace the
contactor
Indicates Error Codes Err1
the bottom probe is well connected reconnect the probe
The value of the resistance of the
probe is approximately 1,1KOhm at
room temperature (1,074 Kohm at
25°C/77°F)
replace the probe
Indicates Error Codes Err2
the top probe is well connected reconnect the probe
the wiring extension of the top plate
probe is well connected
reconnect the wires
The value of the resistance of the
probe is approximately 1,1KOhm at
room temperature (1,074 Kohm at
25°C/77°F)
replace the probe
The unit never reaches operating mode
The top plate temperature is not reaching
the temperature setting
cabling of the upper plate to the ter-
minal block, is connected , check also
connection between terminal block
and power board => connector 5 on
position 5 on the board + continutity
test between terminal block and board
connect the wires in the good
position on terminal block and on
the board.
the probe connector SUP is connected
in position SUP on the board ( lumberg
black connector).
connect the connector SUP on the
board
