- On old appliances (before 2006): prepare the appliances with the
Service Solution "New air baffle cover kit" as described in the
Bulletin 4812 711
- On 2007 and 2008 not Biruni appliances: change the Main Board with a
new one introducing a complete damper sliding door operation (opening-
closing) every 25 minutes, as described in the
40303. Ice formation is avoided by the periodical operations of the air
baffle which are 'cleaning' the slide path.
(*) Note: After 2006 range, the failure indication on the display will be shown only in the first 10 minutes. To
see the indication again, plug out and plug in the appliances.
