Fisher &Paykel Aquasmart washing machine model WL80T65C Make 93220 B. fault 49. Looked up on line and it said hot/ cold water valves. Purchased a set and replaced them. Still say fault 49. Thank you

Fault 49 usually points to the cold inlet valve, either open circuit or not connected correctly. I often come across machines that the motor controller is the problem too.

Fault 49 usually points to the cold inlet valve. I have come across many with this fault that the valve tests ok and it needs the motor controller replaced.

Assuming you have already done what you said you have done, now it is time to do some real troubleshooting.(Dont worry, if you have gone this far you'll be able to do what I'm going to tell you)

First take the lid off. To do this, open it, and lift up on one side, it should come right off. Now take the control panel cover off. There are two screws on the back side of the washer holding it on. You'll need to wiggle it a bit to get it off. Once the cover is off you should find a plastic bag with a "service" sheet in it. The service sheet explain how to put the machine into the "Test Mode". This is very easy to do and will allow you to check out all functions. One of the test, allows you to check the cold water inlet valve. Assuming your water pressure is good and you have indeed cleaned the screen filter going into the machine you will most likely find that the cold water valve is not opening all the way and will need to be replaced. If your handy with a phillips screwdriver you only have two more screws to take out and the valve assembly will come right out.
Don't think you can swap out the hot water valve with the cold water valve. Fisher Paykel, clever as they are made sure you can't do that. One is a proportional valve and the other is a digital valve. They both look identical but they are not!
If your going to do the repair yourself (you've come this far, why not see it through to conclusion), be sure when you call Fisher/Paykel to order the cold water inlet valve that you give them the serial number of your machine to be sure you get the correct part.
Good Luck!

you can swap the hot and cold valves over and see if this fixes the problem as it sound like your cold valve is faulty but not the hot valve.

Cheers
