Hotpoint, Indesit, Ariston, Whirlpool Cooker Hood Fault Finding & Diagnostic Repair
How to Repair a Cooker Hood Faults?
This guide will cover various brands including Hotpoint, Ariston, and Whirlpool. We will take you through the process of checking your appliance for faults, changing components such as filters, light bulbs, light bulb fittings, printed circuit boards (PCBs), and testing the motor.
Different cooker hoods have different types of bulbs, some have 220 to 240 volt bulbs, while others have low voltage bulbs. If your cooker hood has low voltage bulbs, it means that there's a transformer in the appliance which changes the voltage for the bulbs. We will guide you through checking the bulb, checking the fitting, and also checking the transformer to help you locate the fault in your cooker hood.
We would recommend you watch our video since we're showing related components and possible problems with the cooker hood extractor.

Safety First!
- Unplug your electrical appliance before starting work.
How to Replace a Lamp Bulb
If one of the lights in your cooker hood is not working, then you normally can change the bulbs yourself. Before starting, ensure that you disconnect the appliance from the electricity supply. The model number is usually located inside the appliance, behind the filters near the motor. Always ensure the lights are turned off and that the appliance is completely disconnected from the electricity supply before starting any work.
The metal filters can be removed by pressing the filter button. These filters are washable, but it's not recommended to wash them in a dishwasher as some are made of stainless steel and others of aluminium, and caustic chemicals can discolor the aluminium filters. It's best to clean them in a bowl of hot soapy water and let the grease dissolve that way.
Please remember that the whole video includes step-by-step and detailed explanations, which may help you reduce your repair time.
Removing the Glass Lens Cover
To replace a bulb, you'll need a small screwdriver. Be very careful as the glass covers are fragile. The whole light fitting is available and you can replace the bulb, which is a 12 volt, 20 watt bulb. Any higher wattage will generate too much heat as they're halogen bulbs.
There are three points on the light fitting. Use a small screwdriver to gently prise the fitting down. Be careful as this glass is very fragile. The glass will come out with the actual retaining band. If it's bent, straighten it before reinserting.
You can see the wattage and the bulb type in the holder on this model of cooker. Remember to never touch halogen bulbs with your fingers as the grease can cause hot spots.
Replacing the Bulb
Once you've removed the glass lens cover, you can now replace the bulb. Gently remove the old bulb from the socket. It's important to handle the bulb with a clean cloth or gloves as the oil from your fingers can shorten the lifespan of the bulb.
After obtaining your new bulb (remember to ensure it's the correct wattage), place it into the socket. You should feel a slight resistance as you push it in, this is normal as it ensures a secure fit. Once the bulb is in place, you can reassemble the light fixture.
Reassembling the Light Fixture & Testing Light
First, place the glass lens cover back onto the light fixture. Be careful to align the cover correctly with the fixture. Once aligned, gently push the cover back into place. You should hear a slight click to indicate that it has been securely placed.
Next, reinsert the retaining band. Make sure it's properly straightened and fits securely. Once everything is in place, you can reconnect your cooker hood to the electricity supply.
The final step is to test your light to ensure it's working properly. Turn on your cooker hood and switch on the light. If it illuminates, then you've successfully repaired your cooker hood light. If not, it's possible that there may be another issue such as a faulty transformer.
Again, our video includes step-by-step and detailed explanations. If you don't want to make mistakes during the replacing and dismantling process, you can watch our helpful video guide to ease your mind.
