Maintenance Tips
-
Daily auto-clean cycle: Run the built-in automatic self-cleaning system to prevent grease, scale, and residue buildup in the cavity.
-
Probe & sensor care: Clean temperature probes after each shift to maintain accurate cooking, humidity, and holding control.
-
Door gasket inspection: Check seals regularly—damaged gaskets reduce steam efficiency and increase energy use.
-
Water system maintenance: Use filtered or RO water to reduce mineral scale and extend steam generator life.
-
Descaling routine: Perform scheduled deliming cycles to prevent calcium buildup in boilerless steam components.
-
Fan & airflow cleaning: Keep fan guards and internal airflow paths free of grease for even heat distribution.
-
Touchscreen protection: Wipe control panel with a soft, damp cloth only—avoid harsh chemicals that damage electronics.
-
Vent system check: Ensure Safevent exhaust and steam release paths are unobstructed for safe operation.
-
Exterior hygiene: Clean stainless steel surfaces daily to prevent corrosion and maintain food safety standards.
-
Preventive servicing: Schedule professional inspection of humidity control, heating elements, and steam system for long-term reliability
