The only way we can diagnose a leak is to take off the front and determine where the leak is coming from while the machine is operating.

Since we cannot be present you will need to do this for us. This is an older model that I am not familiar with, but I think there is a service panel in front which will come off. If not, the whole front should come off by either unscrewing at the bottom, or releasing clips by inserting a screw driver or putty knife in the gap between the top and the front.
