Pre-Visit Guidance

These issues are not covered under warranty. Please confirm the below have been reviewed before requesting an engineer.

Extractor not working

There is power to the unit To check if power is reaching your extractor unit, If the unit is plugged into a socket, try plugging in another device to confirm the socket is working. Look for any lights, display indicators, or response from the controls. You can also check your consumer unit to see if the circuit breaker has tripped. If everything appears to be in order and the unit still doesn’t power on, it may require a service visit.

The isolator switch has not been turned off An isolator switch (also known simply as an isolator) is a manually operated electrical switch that completely disconnects a device or appliance from the mains power supply. It’s typically used as a safety feature, allowing maintenance or servicing to be carried out safely without the risk of electric shock or the appliance turning on unexpectedly.

In the context of a kitchen extractor or cooker hood, the isolator switch is usually mounted on the wall nearby—often above either in or above kitchen cabinets or near the appliance. It lets you easily cut power to the extractor without switching off the entire circuit.

Think of it as a dedicated “off switch” for the extractor, separate from the main controls, to ensure it’s completely powered down when needed.

All relevant fuses have been checked To check that all relevant fuses have been inspected, start by locating the fused spur or plug that supplies power to the extractor. If your extractor is connected via a fused connection unit (FCU), carefully switch off the power and remove the fuse using a small screwdriver. Visually inspect it for any signs of damage or use a replacement fuse of the same rating (usually 3A or 5A) to test it.

If the extractor is plugged into a socket, unplug it and check the fuse inside the plug. Again, replace it with a fuse of the same rating if you’re unsure whether it’s working.

Finally, check your consumer unit (fuse box) to ensure the relevant circuit breaker hasn’t tripped and that no fuses have blown. If you’re unsure or uncomfortable with any of these steps, it’s best to consult a qualified electrician.

The red reset button is switched on The red reset button is located inside the body of the hood, and can be accessed by removing the grease filters.

Extractor performance

The ducting is the correct size To check that the ducting for your extractor is the correct size, start by measuring the diameter of the ducting connected to the extractor unit. This can usually be done by removing the cover or checking the point where the duct attaches to the extractor.

Westin extractors require ducting that is a minimum of 150mm (6 inches) in diameter for optimal performance. For higher-powered models, the recommended diameter may be greater. For standard products, the website product page includes either the technical data sheet, or the product line drawing that indicate the ducting exit dimension.

If the ducting is smaller than required (e.g. 100mm or 4 inches), it will restrict airflow, reduce efficiency, and cause increased noise. Please note that the indicated duct size requirement must be maintained along the entirety of the duct run, with no areas of reduced size.

Also, check the length of the duct run and the number of bends—long runs or multiple sharp bends can further reduce performance, even if the diameter is correct.

If you’re unsure, refer to the manufacturer’s installation guide for the recommended duct size and layout, or consult a qualified installer.

The ducting is free of blockages, kinks, or damage Ducting should be free of blockages, kinks, or damage because any obstruction can restrict airflow, reducing the extractor’s efficiency. Blockages or damage can cause the unit to work harder to push air through, which may lead to increased noise, decreased performance, and higher energy use. Additionally, restricted airflow can cause moisture and cooking odours to build up instead of being properly vented outside. Keeping the ducting clear and intact helps ensure the extractor operates smoothly and prolongs the life of the appliance.

The non-return valves are not obstructed Non return valves (or backdraught shutters) are shutters that allow air to be blown out, but remain shut to air blowing in the opposite direction, caused by external wind. To check that the non-return valves are not obstructed and can open freely, start by locating the valve directly on the ducting side of the motor within the hood (or for remote motors on the exit side). There may also be a non-return valve in the ducting if applicable, usually positioned where the extractor vents to the outside. Visually inspect the valve for any visible debris, dirt, or damage that might block its movement. Gently try to open the valve by hand or blow air through the duct to see if it moves smoothly without sticking. If the valve feels stuck or is obstructed, clean it carefully or replace it if damaged to ensure proper airflow and prevent backdrafts.

The external vent is not blocked To check that the external vent is not blocked, go outside to where the extractor duct exits the building. Visually inspect the vent cover or grille for any signs of blockage, such as leaves, dust, bird nests, or debris. If there’s a flap or louvre, make sure it can move freely and isn’t stuck closed. You can also briefly turn on the extractor and check whether air is flowing out of the vent. If little or no air is coming through, or the flap doesn’t open when the extractor is running, the vent may be obstructed and should be cleaned or cleared.

Grease filters have been cleaned or replaced Grease filters are panels, made of metal mesh or stainless steel “baffle” style bars, that sit inside the underside of your extractor hood. Their purpose is to capture grease and oil particles from cooking vapours, helping to prevent build-up inside the extractor and ducting. To clean metal grease filters, remove them from the extractor and soak them in hot, soapy water for about 10 to 15 minutes. After soaking, scrub them gently with a soft sponge to remove any remaining grease, then rinse thoroughly and let them dry completely before putting them back. Westin grease filters can also be cleaned in a dishwasher using a hot cycle, though it’s best to avoid heavily soiled loads. Replacement grease filters can be ordered from Westin if required.

The charcoal filters have been cleaned or replaced Charcoal filters (also known as carbon filters) are used in recirculating extractor hoods—those that don’t vent air outside but instead filter and return clean air to the kitchen. These filters absorb odours and impurities from cooking fumes using activated charcoal, helping to keep the air clean and fresh.

Some charcoal filters can be regenerated by following the steps in the product manual. The relevant product manual can be found in the download section of the individual product pages on the Westin website. Replacement charcoal filters can be ordered from Westin.

Nature of the Fault

Partially Working
(tick any that apply)

Lights Work To check that the lights on your extractor are working, first ensure the power to the unit is on and the isolator switch (if present) is in the ON position. Then press the light control button or switch on the extractor to see if the lights come on.

Fan works To check that the fan on your extractor is working, start by making sure the unit has power and that the isolator switch is turned on. Then, press the fan power button or select one of the speed settings. You should hear the fan motor start and feel air being pulled up through the filters. If your extractor vents outside, you can also check the external vent to see if air is being expelled. If there’s no sound, no airflow, or only lights come on, the fan may not be functioning and could require further inspection.

Works but stops after a period of time

Switches are illuminated when pressed, but nothing happens.

The hood turns on by itself Please follow the frequency change instructions in the product manual, available to download from the relevant product page on the Westin website.
