, this front load washer was washing properly, but the customer noticed water inside the wash basket between loads. Often times, if a day or two went by between washes, the amount of water in the tub would be enough to get very close to the front of the washer. Each time, the customer would simply set up a drain and spin cycle to get rid of the water, but the water continued to be a problem
Washers like any other appliance that use water, have a valve or valve assembly to control water entering the tub. These valves utilize a magnetic coil that when energized, will open a plunger inside the housing allowing water to flow. Once power is removed from the coil, the plunger will close due to water pressure from the line and stops the water from flowing. Because it is the water pressure that holds these valves shut, they are always in the off position when not in use.
Since the complaint was water leaking into the tub, the logical source of the leak would be from one of the water valves. A quick way to test if it is the valve or a control that is causing water to leak is to simply unplug the machine from the outlet. If water is still leaking, the valve is bad. If on the other hand the water stopped when the unit was unplugged, this would indicate the leaking valve was being energized and the power source is at fault.
The leak on this unit was to slow to use the above test, but because it was slow, this did indicate the valve wasn't being energized. The only thing remaining then is a leaking valve. Sometimes these valves just fail, and other times it's due to sediments getting stuck in the plunger preventing it from seating closed. Either way, it's time to replace the water valve.
I replaced the valve assembly since all three valves come together as a unit, and put everything back together ensuring the colored connectors were securely fastened to their like colored valves. Reattached the water supply lines and all was well with this washer. A call back to the customer a week later confirmed my repair worked.
