Thread: gwl 11 fill valves

In my troubleshooting, after I swapped the valves for testing purposes, I filled the tub with hot water from buckets to accelerate the filling process. The wash and especially the rinse cycle is MUCH faster.
My assumption is that the cold fill valve is faulty. Has been all along, however it is almost completely faulty now. Solenoid gets pretty hot. Understandable since it is "on" for an hour at a time. I have city water with a pre-filter and softener, the inlet screen is clean.

Also, a theory of operation question: During the rinse cycle, does the washer fill for a predetermined amount of time, or is it a predetermined amount of water?
Thank you.

The water inlet valves are different and should not be interchanged. The cold valve is proportional. The hot valve is either "off" or "on"

You should not manually add water to the tub; this will only serve to confuse the machine's controller. Plus incoming water temperature is monitored by a thermistor in the mixing chamber.

The water level is not determined by time; Fisher Paykel washers have both a "manual" water level setting as well as an "automatic" setting.

For manual settings, the machines use a pressure dome on the side of the outer wash tub, with a plastic line leading to a transducer (water level sensor) to properly determine the water level.

For "automatic" the machine will sense the load size and fill to a level sufficient to wash the load using as little water as possible, via the "floating basket" to determine the correct level of water in the tub. As the washer fills with water, the inner basket actually begins to float (lift up) and move on the splined shaft it rides on. if there is too light of a load for the machine to sense, it will default to a minimum water level.

If there is a problem with the COLD inlet, the machine is capable of sensing this condition and will generate fault code 49. However it will not do this 100% of the time. It can also generate fault code 48. If you check the resistance of the valve coils using a good ohm meter, the resistance should be in the area of 64 ohms. Keep in mind that a valve can be "good" electrically (correct resistance reading) but be faulty "mechanically" and not operate as intended even if the proper resistance is present in the coil and the correct supply voltage is coming from the machine control.

You may have a problem with the proportional (COLD) inlet valve. We are not telling you to order one, or saying this is the problem, but it very well may be a faulty cold water inlet.
