Answer to continue safely
Is it safe to keep using?
Yes. The hood is safe to use, but significantly degraded airflow means cooking byproducts are not being properly captured. Clean or replace the filters before the next heavy cooking session.
Can I reset the code?
Yes. After cleaning the filters, the filter indicator (if equipped) can be reset following the procedure in the model-specific user manual.
When to stop immediately?
Stop if you notice: Grease is actively dripping from filters onto the cooking surface, Visible grease accumulation inside the hood canopy above the filters.
Symptoms You May Notice
Filter cleaning indicator light is illuminated
The hood control panel shows an active filter reminder indicator, signaling the grease filters have reached their scheduled cleaning interval.
Grease visibly dripping from filters during cooking
Liquid grease is observed dripping from the filter mesh during or after cooking, indicating the filter is fully saturated and can no longer absorb additional grease.
Noticeably reduced airflow compared to normal
Hood performance has decreased significantly — smoke and steam are less effectively captured than they were when filters were last cleaned.
Grease smell from the hood even when not in use
A stale grease odor is detectable from the hood area at rest, caused by accumulated grease on the filter mesh off-gassing at room temperature.
Possible Causes
Overdue filter cleaning interval
DCS recommends cleaning stainless mesh grease filters monthly under normal use, and more frequently when cooking high-fat foods regularly.
DIY PossibleFilters not cleaned after a high-grease cooking event
A single extended session cooking fatty meats or deep-frying can saturate filters that were otherwise on a normal schedule.
DIY PossibleSafe Checks You Can Do
-
1
Remove and clean grease filters
Remove all mesh grease filters from the hood. Wash in the dishwasher on a hot cycle, or soak in hot water with dish soap or a degreaser for 15 minutes, then scrub with a brush. Rinse thoroughly and allow to dry completely before reinstalling.
Filters must be completely dry before reinstalling — moisture on the filters can be drawn into the blower area.

Reset the filter indicator if equipped
Consult your DCS hood model's manual for the filter indicator reset procedure. Typically this involves holding a specific button (often the fan speed button) for 3–5 seconds while the hood is on.
If you do not have the manual, the DCS website has downloadable PDF manuals for all current VS and ES series models by model number.
When to Call a Professional
Contact a qualified technician if:
- Heavy grease buildup has migrated into the blower wheel area — requires blower cleaning
- Filters show physical damage (bent, torn) and need replacement rather than cleaning
