What do I do if...?
The behr Kjeldahl heating block has an internal fault
scanning system. This is capable of detecting five dif-
ferent error situations. „Error“ will then appear on a red
background, together with a Code No., on the display. An
alarm signal (bleep tones) is also heard. The numbers
have the following meanings:
Code Meaning Remedy
002 The temperature sensor is not detected. Notify the behr after-sales service.
003 Short-circuit on the temperature sensor.
010 The thermal cut-out on the heating block has
tripped.
Switch the device off and allow the heating block to cool
for a while. Make sure the % function has not inadvertently
been selected in your temperature program. Reset the
termal cut-out before switching on again (see below).
The heating system or the triac control
system of the digester unit is defective.
Notify the behr after-sales service.
011 The device heats without stopping.
100 General error.
Resetting the thermal cut-out:
You find the thermal cut-out in the rear of the device. In
the boring above the power socket there is a small green
lever. Press this lever downwards with a screw driver.
It will engage with a click. If it doesn‘t, the cause of the
malfunction is elsewhere; notify the behr after-sales
service.
If it is not possible to switch the appliance on at all (the
display remains dark), it is possible that a mains fuse
has tripped. Switch the appliance off and on again after a
few minutes. Notify the behr after-sales service if it is still
not possible to switch the appliance on or if the problem
occurs repeatedly.
If the thermal cut-out keeps tripping:
It must be possible to heat the block to 430 °C. If the
thermal cut-out keeps tripping before reaching digestion
temperature, please notify the behr after-sales service.
