I had a call out to this one today, it appears to be leaking from the bottom of the door.
I am guessing it is the seal, although it looks okay. I tried to order one but it is coming up as no longer available (Connect list an alternative) I wonder if anyone is aware of a mod?
Also overfilling from that lovely water matrix behind the left side panel……sticky level float microswitch, scaled or general crud in the tubes of the matrix, blocked lower transfer hose from sump to matrix……. 😉
