Some of our washing machines have a drum cleaning function button/indicator on them, this indicator will flash up to remind the user to start the drum cleaning cycle after every 25 full cycles of the washing machine.

To activate the drum cleaning mode, you need to hold down the drum cleaning function button for 3 seconds, this will start a short cleaning cycle of the unit.  You may put washing machine cleaning products from the supermarket into the drum before starting this clean however this is not essential.  Once the cycle is complete, the 25 cycle count will restart.
