Full Engineer Test Mode
This special mode is for testing single components of the control board. It can only be activated
within 10 seconds of the power being supplied and as soon as the cavity temperature has been
evaluated.
If the cavity temperature is higher than the door locking temperature, the door gets locked and the
test mode cannot be entered.
To enter test mode, turn on the appliance and within 10 seconds, turn the mode selector switch to
the ‘Self-Clean’ position and press timer buttons 5 and 6 together.
The display reads ”tE” for test mode.
To exit test mode and return to power on mode, press timer buttons 5 and 6 again. If no button is
pressed within 25 seconds, the test mode is automatically abandoned and the control returns to
power on mode.
The test mode is performed in 3 levels:
Level 0 Outputs, button and function test. Also program information.
Level 1 Inputs test
Level 2 Analogue (AD) values test **
When entering the test mode, the default level is level 0. To change the level, keep timer buttons
2 and 3 pressed.
The display reads "tE °x" while the degree sign flashes. Pressing the PLUS/MINUS key will set the
actual test level 0, 1, or 2.
**Test level 2 is not mentioned in this section as it is only applicable to the internal software
configuration and is not considered relevant to general service and repair work.
