The amount of powdered detergent to use in a washing machine depends on the manufacturer's recommendations for the detergent and the water hardness in your area. Generally, front load washing machines require less detergent compared to top load machines, as they use less water and have a different washing mechanism.
A common guideline for front load washing machines is to use about 1 to 2 tablespoons of powdered detergent per load. However, it's essential to refer to the detergent packaging for specific instructions and dosage recommendations. The detergent packaging typically provides guidelines based on the load size and water hardness.
Since you have a 7kg front load washing machine, you can start with 1 to 2 tablespoons of powdered detergent and adjust the amount based on your specific washing needs and the soil level of the clothes. If you have very hard water, you may need to use slightly more detergent, but be cautious not to overuse detergent as it can lead to excessive suds and residue buildup in the washing machine. Always follow the detergent manufacturer's instructions for best results.
