Frequently Asked Questions - A451 Kohersen

How to use the kettle for the first time?

Before first use, fill the kettle with cold water to the MAX level (1.7 L), boil it, then discard the water. Repeat the process twice to remove manufacturing residues.

Why does the kettle not turn on?

Check that the kettle is properly plugged into a grounded outlet and that the ON/OFF switch is pressed. If the overheat protection has activated, wait for it to cool down.

How to clean the anti-scale filter?

Remove the filter from the kettle, rinse it under running water and gently brush it with a soft brush. For deep descaling, use white vinegar.

What to do if the water does not boil or the kettle turns off too early?

This may be due to scale buildup. Perform regular descaling with white vinegar or a suitable descaling product.

Is it normal for steam to come out of the spout?

Yes, hot steam escapes from the spout during boiling. Do not lean over or touch the spout.

How to descale the kettle with white vinegar?

Pour white vinegar into the kettle until it covers the bottom (about 1.5 cm). Let it sit overnight, then empty, rinse, and boil fresh water twice.

Why does the lid not open?

Scale deposits may block the mechanism. Clean the kettle and lid, then try again.

Can you boil less than 0.5 L of water?

When you have finished using the kettle, disconnect it from the power source (earthed socket), wait for it to cool down and wash the kettle according to the procedure described in section 5. Cleaning and maintenance.

3. OPERATION AND USE OF THE DEVICE

3.1. Before first use

Do not open the packaging without due care and attention and using a sharp knife or other sharp objects, as this may damage the device. Remove all parts of the device and the operating manual from the box, remove the protective films and then check that the contents of the package are complete and that the individual parts are not damaged. If you notice any irregularities, do not use the damaged parts and contact the service centre at the address specified in section 8. Warranty and service.

Important: Before using, follow the instructions below.

• Remove all packaging and protection elements from the kettle and keep or dispose of them safely in accordance with local recycling regulations. Keep plastic packaging materials out of the reach of children.
• Unwind the power cable to its full length and inspect it for damage. Do not use the device if the device or its power cable is damaged or not functioning properly. In case of damage, contact the Customer Service for advice on the inspection, repair or return of the damaged product.
• Keep the operating manual and proof of purchase of the product for future reference.
• Make sure the switch is in the OFF (up) position before connecting the device to a power source (earthed socket).
• Lift the device vertically from the power base, open the lid and pour cold water into the device to the MAX level (1.7 l) and boil it, then pour out all the water. This is done to remove residues from the production process and transport.
• Repeat the above procedure twice before using the device to boil water for drinking. Your new kettle is now ready to use.

3.2. Automatic switch-off

The device is equipped with an automatic switch-off function. It shuts off the power to the device when it is empty to prevent accidental use without water.

After activating this safety function, disconnect the device from the power source and allow it to cool down for a few minutes before refilling with water. The boil-dry protection will reset and the device will be ready for use again. If the device is still at too high temperature, the safety feature will not allow it to start until the appropriate temperature is reached.

3.3. Kettle operation

• To fill the kettle, remove it from the power base, press the lid opening button to open it, fill it with the appropriate amount of drinking water and then close the lid.
• Make sure the kettle is filled with water at least to the MIN level, but not above the MAX level.

Too little water will cause the kettle to turn off before the water boils. Too much water will cause hot water to spill out of the spout during boiling. Be careful not to let water spill onto the power base.

- Make sure the lid is closed before placing the kettle on the power base.

- Plug the power base with dry hands into a power source (earthed socket).

- Press the ON/OFF switch.

- The control lamp will illuminate and water heating will begin. Do not open the lid while the device is running.

- The kettle will automatically turn off when the water boils: the ON/OFF switch will return to the OFF position and the control lamp will no longer be illuminated.

The lid must be properly closed for the automatic switch-off function to be active. To stop the heating process at any time during operation, remove the kettle from the power base or slide the ON/OFF switch upwards.

- Wait until the water in the kettle has stopped boiling completely before pouring the water out of the kettle. Remove the kettle from the power base by grabbing the handle and lifting it.

When pouring water out of the kettle, be careful not to get burned by hot water or hot steam. Do not open the lid when the water in the kettle is hot.

To reboil the water, allow the kettle to cool down for 15-20 seconds before pressing the ON/OFF switch again to boil the water.

Hot surface! The body, spout, filter and lid heat up and are very hot during operation. Only touch the handle and the cool touch zone of the device (see section 4. General device information).

Always disconnect the kettle from the power socket and allow it to cool down before cleaning. Never submerge the device, cable or power base in water or any other liquid and never rinse with water or detergents!

5.1. Cleaning the kettle

• Use a soft, moist cloth and a mild, non-abrasive detergent to wipe the outside of the kettle. Then dry the outside of the kettle using a soft, dry cloth.
• To prevent damage to the surface of the kettle, do not use scourers, steel wool (wire brushes), solvents or harsh chemical or alkaline cleaners.
• Essential oils and organic solvents, e.g., lemon juice or orange peel juice or cleaning agents containing acetic acid, can damage plastic components.

5.2. Cleaning the filter

• Clean the filter regularly to ensure its proper function, i.e., trapping limescale particles and preventing them from falling in when water is poured through the spout.
• To clean the filter, remove it (see section 4. General device information) from the kettle and rinse it under running water. Then wipe the filter with a soft brush.
• To prevent damage to the filter, do not use tools or cleaning agents that could tear or damage the filter during cleaning.
• If the above steps do not completely remove the limescale from the filter, descale the device (see section 5.3. Descaling).

5.3. Descaling

• Descale the device regularly in order to obtain the best possible results from its operation. The frequency of descaling depends on the hardness of the water poured into the device and the frequency of use.
• It is recommended to carry out descaling using commercially available limescale removers intended for domestic appliances. When using this type of product, carry out the descaling by following the instructions on the packaging of your product.
• If limescale remover is not available on the market, the descaling process can be carried out using white vinegar. If using this type of product, carry out descaling by filling the kettle with enough white vinegar to cover the bottom of the kettle to a depth of about 1.5 cm, leaving it in the kettle overnight. Do not switch on the device during the descaling process.
• It may be necessary to repeat the descaling process several times with white vinegar until the limescale deposit is completely removed. Remember to use fresh vinegar every time.
• Once the descaling process is complete, empty the kettle and then fill it with fresh, clean water. Start the device bringing the water to the boil and then empty the kettle.
• Repeat until all traces of white vinegar have been removed.

5.4. Storage

• Before storing the unit, clean it according to the attached manual (see section 5. Cleaning and maintenance).
