After drying a fair amount of clothes, when the the water container is pulled out for emptying, water runs down the front of the machine. This happens even although the container is less than 1/3 full, as it is emptied every time the machine is used.
It would appear that some of the condensed water is not dripping into the plastic container, but down the side of it and gathering inside the drawer compartment, and then flowing out when the container (drawer) is removed from inside the machine.
The clothes are drying as normal, and there is no sign of any other abnormality.
