6-2TOUCH CONTROL BOARD ERROR CODESError Description
U400 U400 appears static on the display and indicates an acoustic signal when the electronics have been
connected erroneously at 400 V. (This warning appears when the measured voltage on the power
grids reaches 280 volts, and cases have occurred in which this warning appears at 250 volts). The
electric company can divert the supplied voltage by ±7%. Disconnect the cooktop from the AC line.
The failure disappears when the incorrect voltage is corrected.
F8 F and 8 blink alternately on the display corresponding to the cooking zone if the maximum cooking
time has been exceeded. The times depend of the power level and go from 1 to 10 hours.
E “E” blinks alternately with the power level or the residual heat indicator when the corresponding sen-
sor has been pressed for too long (> 5 seconds), thereby sounding the acoustic signal. When the
“on” sensor is pressed for more than this time, “E” appears on all displays. It can occur due to liquids
spilled over the sensor zone, or due to an object that has been left on top. The indicator disappears
when the problem has been removed from the sensor and any other key is pressed.
F2 F and 2 blink alternately on the corresponding display if the NTC temperature of the touch control is
excessively high (>100°C). If F2 appears, cooking zones 1 and 4 will not work.
F4 F and 4 blink alternately on the corresponding display if the NTC temperature of the touch control is
excessively high (>100°C). If F4 appears, none of the 4 cooking zones will work.
ErXY The touch control has an internal failure (except with Er32).
Er32 This warning occurs when a touch control of a 2l cooktop is connected to a 4l cooktop, or vice versa.
Check the replacement part.
Cl The line power supply voltage is too low.
