Clean out the conditioner tank
The fabric conditioner can sometimes build up and block parts of the dispenser tank. Try cleaning the soap drawer by first removing it from the machine. Pull the drawer by opening it and then grasping the sides and pulling it out. A firm pull may be needed to remove the drawer. In the centre of the drawer is the fabric conditioner compartment and the top cover can be easily removed to make cleaning easy
Pull the top cover off and clean it along with the drawer in your sink using some warm water and a mild detergent. Its worth turning the drawer over and making sure the drain hole is clear
Also clean the tube attached to the cover removing any build-up of soap powder or conditioner. When its clean pop the cover back onto the conditioner compartment and re fit the drawer to your machine.
