3. Cleaning of Nozzle
The water nozzle can be dismounted and cleaned according to needs. The easiest way of cleaning
the nozzle is by soaking it in scale remover for approx. 6-8 hours. When remounting the nozzle, note
that the small notch will turn upwards, see the figure below.
4. Exterior
Cleaning
The oven cabinet is washed with soapy water and then dried with a soft and moist cloth. After drying,
steel oil is to be added (refer to directions on the packing). Note! The exterior of the oven is never to
be flushed with water hose or high-pressure cleaner which may damage the electronic components
.
Troubleshooting
Error Codes
The BKI Combi ovens have an automatic error detecting system. In the event of malfunctioning of the
oven or faulty connection, error codes (for S or VS controller) or messages (for CVC controller) appear in
the display. This means that any defects are specified immediately and can be remedied quickly and
efficiently, which again means fewer interruptions of operation and thus fewer service calls. The following
list of error codes provides you with a brief description of each error code and an indication as to how the
fault can be remedied.
