Hey @Dan Griffiths1 ,
that may be the Pre Wash symbol – If you’re washing items that are heavily stained or soiled, it can help to add a Pre Wash. This simply adds a short wash cycle before the main wash to help remove any stubborn stains. However, in order to confirm this, would you be able to provide me with the appliance model code? This can be found on the door on a white sticker.
