Right! I got this one home this afternoon to investigate.
It’s a self clean machine. The way it does this self clean is to dump the water held in the water tank (via a flap and solenoid) onto the front of the condensing unit. This is designed to disturb and remove any fluff/lint accumulating on the condenser grill.
Part number 00657920 is responsible for diverting water to the water tank ready for a self clean, if the customer has the machine set up to drain the water out of the machine into a down pipe etc. It needs to reroute the water to the tank to be able to self clean.
The machine was showing Care in the led display.
This message will initiate relative to time when a manual care maintenance program is needed.
As far as I can tell, the leak has been caused by fluff and lint against the seals in the front LHS window which allows access to the condensing grill.
I’ve cleaned up all the seals/windows, ran a cp1 maintenance cycle and she’s a s good as new!
Bravo!
