Why is my BRANDT LMHT2060W wall-mounted decorative hood making a loud noise and not extracting properly?

Question

Accepted Answer

A loud noise and poor extraction from your BRANDT LMHT2060W hood can have several causes. These issues are generally due to a buildup of grease in the cassette filters or insufficient ventilation in the room. Here are the checks to perform in order:

Clean the cassette filters as a priority. These filters play a significant role in the efficiency of your hood and should be cleaned approximately every 30 hours of use, or at least once a month. A clogged filter significantly reduces airflow, which increases the noise from the motor that has to work harder. Rotate the integrated handle of the cassette filter to remove it, then tilt it downwards. Clean the filters with warm soapy water using a soft brush, or place them upright in your dishwasher. Rinse and dry them thoroughly before reinstalling.

Check the ventilation in your kitchen. The hood needs sufficient air intake in the room to function properly. A poorly ventilated or airtight kitchen prevents the hood from effectively extracting air, leading to reduced airflow and increased noise. Ensure that a window or door can be opened in the kitchen to allow for air circulation.

Select the correct operating speed. Your LMHT2060W hood has three speeds: low, medium, and high. The selected speed should be adequate for the amount of smoke and steam produced. Excessive noise may occur if you unnecessarily use the maximum speed; try the medium speed first, then increase if necessary. Note: a beeping sound occurs each time you change speed, which is normal.

In recirculation mode, check the charcoal filter. If your hood operates in recirculation mode (without external venting), an active charcoal filter must be installed to retain odors. Replace it approximately every 120 hours of use, or at least once a year depending on your usage. A used charcoal filter reduces extraction efficiency. If you have an external vent, ensure that the exhaust duct is not blocked or bent, which would limit airflow.

If the problem persists after these checks, contact the authorized BRANDT after-sales service. The abnormal noise may indicate a mechanical defect in the motor that requires professional intervention. Mention that you have already cleaned the filters and that the ventilation is sufficient to facilitate diagnosis.
