I am having a water inlet problem. The hot water comes in just fine but the cold water just kind of trickles in. Just finished replacing the water inlet valve assembly and is still doing the same exact thing. Was wondering if I could get a copy of the service manual and any expert advice on where to go from here. Thanks.

OK, after seeing another post how to go into svc mode, found 2 errors. One said something about an inverter problem and another about a communication error between the main pcb and the inverter pcb. Didn't realize they would clear through the process and I didn't write them down to be exact on the message.

I assume the inverter is part of the main PCB correct? Thanks for the manual, greatly appreciated.

Ummmmm...LMAO. Found the problem. Never thought a hose could go bad. Guess the barb inside the hose broke and turned sidways making almost a complete blockage on the cold water side. Ran a copper grounding wire through the hose and turned it straight again. Everything works perfect now. Feel like an idiot, I know better, KISS is something I always practice but forgot this time.

Thanks for your help again :D

Yeah I know...kicked myself is the a$$ for it. Funny thing is I am an electronic tech....so I had the schematic out and meter and tested almost every single circuit on the inverter and main pcb. Was going at it for a couple hours.
