Combi-Oven Maintenance

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.
