  • Foam and detergent powder residue in washing machine.

Applies to

  • Washing machine

1. Clean the machine – run repeated washes at the highest temperature without detergent, until it does not produce any more foam. (You may need to do this several times).

2. Clean the machine with a washing machine cleaner. 

3. Carefully follow the detergent powder manufacturer’s instructions on dosing.

4. Try washing using a different brand of detergent.

5. Run a maintenance wash regularly (Cotton cycle at 90°C at least once a month)

6. Use the extra rinse function.

7. Make sure you're using the correct cycles intended for the clothing type.

Note:  Excessive foam in the washing machine is not covered by the warranty, as it is not a machine fault.


The reason for excessive foam in the washing machine is excessive detergent or another agent that has been used.

  • Adding too much detergent is genuinely the cause (Overdosing of detergent).
  • A build-up of detergent powder residue in the machine caused by adding too much detergent and washing regularly at low temperature.
  • Washing fabrics that have already been saturated with detergents. (Clothes that have been pre-soaked)
  • Too low water hardness (in some home are installed water softener), for low water hardness you should follow detergent manufacturer label
