"Fault" pilot lamp (heating system not enabled):
This pilot lamp lights up during the fresh-air rinsing operation and when there is a fault in the
ventilation or heating system, it indicates that the unit is not ready for use.
If the temperature class is changed from T3 to T4 when the temperature in the inner
chamber is >70°C, the red pilot lamp also indicates that the required parameters have not
yet been fulfilled. Wait until this lamp goes out before loading the unit.
The lamp goes out automatically when the rinsing operation has been completed or the fault
has been eliminated. Do not use the unit if this light stays on. The unit may not be used until
the cause of the problem has been found and eliminated (by an authorized service center
where applicable).
