Maintenance and grease filter cleaning
Grease filters should be cleaned once a month. This is to guarantee the best possible extraction capacity. Boretti recommends that you clean your grease filters with non-corrosive detergents. Stainless steel grease filters are dishwasher safe. Aluminium or metal grease filters aren't dishwasher safe. In the long run, cleaning aluminium or metal grease filters may give your grease filter a whiter colour.
Tips for manual cleaning
- Use a special cleaner that's meant for cleaning hood filters; you can also use undiluted detergent for this.
- Apply the detergent to the filter and let it sit for a few minutes.
- Once the detergent has sat for a bit, clean the filter with a dish brush and hot water.
The extraction capacity is insufficient
The exhaust duct has a major influence on the capacity of the cooker hood. Each 90-degree bend reduces the extraction power by about 10%. As the drain gets older, grease formation can cause the blades of the discharge grille to become jammed. Dust, or even a bird's nest, can also obstruct the drainage. In addition, the grease filters should be cleaned monthly for the best extraction capacity.
Recirculation generally leads to a reduction of 20-30% of the extraction power. Make sure that carbon filters are replaced every 4-6 months. If you don't replace the filters, the grease formation will inevitably cause a reduction in extraction.
The cooker hood makes too much noise
The cause may be found in your exhaust air duct:
- It may be too long.
- It's clogged.
- Or blocked by a kink.
If your cooker hood is equipped with a recirculation system, noise can be caused by the following:
- The carbon filter isn't correctly positioned, which causes air to pass through the carbon filter, in turn causing noise.
- Your drainage hose is too small in diameter.
- The carbon filter is saturated. This occurs over time. This reduces the amount of air passing through the carbon filter. Your cooker hood will then produce more noise. A solution is the use of a plasma filter which, in addition to operating better, is silent.
The cooker hood rattles while on a higher setting
Does your cooker hood rattle only when it's on the highest extraction setting? Then this is caused by too high of a counter-pressure in the drain. Counter-pressure occurs when the drain is too long, has too many bends, or is too narrow. If the wall outlet or the drainage hose is too small in diameter, this will also affect the noise level. If the cooker hood rattles on all settings, this may be due to a technical defect. In that case, please contact our Customer Service.
Defective LED lamp
We recommend that defective LED lamps be replaced by a Boretti Service Center mechanic or a qualified electrician.
A blue light lamp appears or keeps flashing
Some Boretti cooker hoods are equipped with an indication button to replace the filter or to clean the grease filter [F-key]. This button will flash after approximately 40 hours of activity. You should then clean the grease filters. After 120 hours of activity, the button will light up, indicating that the carbon filters need to be replaced.
To prevent the button from staying lit after the grease filter has been replaced or cleaned, reset the unit by pressing the button for 10 seconds.
Reset the cooker hood
Have you replaced or cleaned the grease filter, and the indicator for replacing the filter or cleaning the grease filter is still on? Then you need to reset the system. You can easily reset the filter indicator by pressing the button for a few seconds, after which the light will turn off automatically.
Carbon filters or plasma filters
Carbon filters and plasma filters are a crucial part of the maintenance and ventilation of your hood when the hood is recirculating. A carbon filter filters the cooking vapours and blows clean air back into your kitchen. The difference between a carbon filter and a plasma filter is that plasma technology goes one step further. A plasma filter is an actual air cleaning device with the important additional advantage that a plasma technology ensures a healthy indoor climate: free of odours, pollen, and bacteria.
The Boretti plasma filter Puro is a circular plasma filter that can be connected to any new and existing cooker hood with a drain diameter of 150 mm. This plasma filter is innovative because:
- Any contamination in the air in both the kitchen and the surrounding room is reduced by 99%. That gives a better result than regular carbon filters.
- There's no need to replace plasma filters. Plasma filters last a lifetime.
- Contaminated air is once again clean without the need for a ventilation shaft to the outside. The additional advantage is that heat saves energy.
- The plasma filter isn't just a filter for cooker hoods. It's an actual air purifier that removes pollen, bacteria, and all allergens from the air, including cigarette smoke.
- The plasma filter doesn't make any noise.
Note: Plasma filters work with a plug. Make sure that a double wall socket is available behind the cooker hood. The length of the plasma filter plug cable is 0.5 meters.
