Answer to continue safely
Is it safe to keep using?
Yes. The hood works normally. Performance is reduced with a saturated filter — clean it soon for optimal extraction.
Can I reset the code?
Yes. Yes — clean the filters, then hold the reset button for 3 seconds with the fan on.
When to stop immediately?
Stop if you notice: Indicator reappears immediately after reset (counter malfunction), Grease is dripping from the filter or hood.
Symptoms You May Notice
Red LED lights up (grease filter icon)
A solid red indicator light appears near the filter symbol on the control panel.
Hood continues to work normally
The fan and lights still function — this is a maintenance reminder, not a shutdown.
Reduced extraction performance
A saturated grease filter reduces airflow and cooking odor removal.
Possible Causes
Grease filter operating hours reached
Miele tracks fan running hours (typically 20–50 hours depending on model). The filter needs cleaning once the limit is reached.
DIY PossibleHeavy cooking without cleaning
Frequent frying, grilling, or high-smoke cooking saturates the filter faster.
DIY PossibleSafe Checks You Can Do
-
1
Remove the grease filters
Open the filter panel (usually clips or slides). Remove the stainless steel mesh grease filters.
Most Miele hoods have 1–3 removable metal filters.
-
2
Clean in dishwasher
Place the metal grease filters in the dishwasher on a hot cycle (65°C+). Or soak in hot water with dishwasher detergent for 30 minutes.
Miele recommends dishwasher cleaning for their stainless steel grease filters.

Reinstall and reset indicator
Once dry, reinsert the filters. Reset the indicator by holding the grease filter button for 3 seconds with the fan running.
The exact reset procedure varies by model — check your manual for the button combination.
