Viking Hood Error Code FILTER

The FILTER indicator means the hood's built-in timer has counted 30 hours of fan operation and is reminding you to clean the grease filter. This is a scheduled maintenance alert, not a malfunction or error. The light will stay on until you clean the filter and press the filter button to reset the timer.

Yes, pressing the filter button will reset the timer and turn off the FILTER light even if the filter has not been cleaned. However, skipping the cleaning defeats the purpose of the reminder. Accumulated grease on a clogged filter reduces airflow performance and increases the risk of a grease fire, so cleaning before resetting is strongly recommended.

In most cases there is no cost at all, since the FILTER light is a maintenance reminder that is resolved by cleaning the existing filter. If the filter is damaged and needs replacement, a new Viking grease filter typically costs in the range of $20 to $80 depending on the hood model. Professional service is not required for this maintenance task.

Remove the grease filter and clean it thoroughly, typically by soaking in hot soapy water or running it through a dishwasher if the filter is dishwasher-safe. Reinstall the filter once it is dry, then press the filter button on the hood's control panel to reset the indicator. The FILTER light should turn off immediately after the reset is confirmed.

The hood will continue to operate normally when the FILTER light is on, so there is no immediate safety shutoff. However, continued use with a dirty or heavily loaded filter reduces ventilation efficiency and allows grease to build up in the filter assembly over time. Addressing the indicator promptly by cleaning the filter lowers fire risk and keeps the hood performing correctly.
