The valves should read 64 ohms but a variance of 5% is acceptable. Fault 49 is the motor board reading incorrect current on the cold valve circuit. Usually due to a bad valve (or wiring problem on it) ... but also can be the motor board is bad.

Thanks for the reply. In diagnostic mode, the tech sheet says the corresponding led should light when either temp up or temp down is pressed. In both cases, the LED lights for an instant, and then goes out, on both hot and cold. Sometime the LED does not light at all.

Am I at the point where I need to pull the control board and look for problems there? I found a site that gives general guidance on testing fuses resistors and such on the board. (http://www.instructables.com/id/How-to-repair-a-Fisher-Paykel-Washing-Machine/) But, I don't think it is exactly my model.

If you can suggest some deeper diagnostics I can try, I don't have much to loose if I need a new board anyway.

Thanks again!

The circuit check on the hot and cold valve occurs immediately upon connection to power and supersedes diagnostics. Pressing Temp Up or Down in diagnostics is to run the hot or cold water ... which can't happen if the valve is bad-circuit.

F&P does not publish component-level information for their boards. The GW609 in the instructional you linked is a Phase 5 Aus/NZ model which is an older series than GWL11 (Phase 6) and has some electrical differences. I didn't read through the comments there in detail but perhaps some of the discussion is relevant.

Ok, thanks mate. No way to determine between new valve or controller board without just trial and error?

Change the valve first, it's less cost than a board.

Parts ordered.

Thank you very much for your help !
