How can I descale my washing machine?

Descaling your washing machine is essential for optimal performance and a longer lifespan. We offer effective solutions such as HG descaler for appliances, specially developed to remove limescale from hot water equipment, and HG washing machine and dishwasher deep clean and service, which helps prevent breakdowns by removing limescale, soap and dirt deposits from critical components. You can also try household alternatives such as citric acid. However, always follow the manufacturer's instructions for the best results and to avoid damaging your appliance. Regular maintenance and tackling the causes of limescale build-up, such as hard water, excess detergent and washing at low temperatures, will help keep your washing machine in top condition. Always check the maintenance instructions from the manufacturer beforehand.

HG solutions for descaling your washing machine

To descale your washing machine effectively and keep it in top condition, we offer the following solutions:

• HG descaler for appliances: A descaling liquid specially developed to remove limescale from hot water equipment, including washing machines. In soft-water areas, pour 100 ml into the detergent drawer. In hard-water areas, pour 200 ml into the detergent drawer. Set the shortest programme to 60°C, pause the machine halfway through and allow approximately 20 minutes for the product to work. Then allow the programme to complete fully. Do not use on acid-sensitive surfaces such as aluminium, zinc and enamel.
• HG washing machine and dishwasher deep clean and service: This product helps prevent breakdowns by removing limescale, soap and dirt deposits from filters, floats, drain pipes and other hard-to-reach components. Sealing rubbers remain elastic and water-resistant, helping to prevent leaks. Fill the main detergent drawer with a full bottle, 100 g, add no extra detergent and select a coloured wash programme at 60°C. Allow the programme to run fully and without interruption, including the spin cycle. Use approximately once every three months.

Solutions for descaling your washing machine

If you are looking for ways to descale your washing machine without using professional products, here are some suggestions using household alternatives:

• Citric acid: Dissolve 100–150 grams of citric acid in warm water and pour it into the detergent compartment. Run the machine on an empty cycle at the highest temperature to loosen limescale deposits.
• White vinegar: Pour 1 litre of white vinegar into the detergent compartment and run the machine on an empty cycle at 60°C. This can help with light limescale build-up and odours, but should be used with caution.
• Regular washing at higher temperatures: Running an empty cycle occasionally at 60°C or higher helps prevent limescale and dirt from accumulating inside the machine.

While these solutions may be effective, they do not always deliver the best results and there may be risks associated with using them in your washing machine. If in doubt, we recommend opting directly for HG descaler for appliances or HG washing machine and dishwasher deep clean and service, which are specially designed for this purpose.

Causes of limescale in your washing machine

Limescale in your washing machine can have several causes:

• You live in an area with hard water, meaning the water contains a high concentration of minerals such as calcium and magnesium. These minerals accumulate in your washing machine and form limescale deposits.
• You use too much detergent, leaving soap residue behind that can contribute to limescale build-up.
• You wash regularly at low temperatures, allowing bacteria and mould to grow and contribute to deposit formation.
• You leave the door and detergent drawer of your washing machine closed after use, trapping moisture and promoting the growth of bacteria and mould.

To prevent limescale in future, consider installing a water softener, using the recommended amount of detergent, washing occasionally at higher temperatures and leaving the door and detergent drawer open after each wash until the inside is dry. Regular maintenance is key to keeping your washing machine functioning optimally. By following these preventive measures, you can significantly reduce the frequency of descaling needed. Remember that prevention is always better than cure when it comes to appliance maintenance.
