Whirlpool's Duet series washers and dryers focus on sleek style and adaptability. They have sensory features and detergent dispensing reservoirs, and come in designer colors. Because the Duet series encompasses dozens of front-loading washers -- including models in the GHW, WFW and YWF ranges, as of 2014 -- your owner's manual serves as your best bet for troubleshooting. When the guide isn't handy, however, you can turn to Duet-specific advice from Whirlpool to get your washer back on track.
Start with the basics before moving on to advanced troubleshooting. Ensure that the Duet's power cord is plugged in to a grounded three-prong outlet; check your home's electrical service panel for a tripped breaker or blown fuse, remedying as necessary. Close the washer's door and its dispenser drawer securely -- a Duet will not operate if these doors are ajar. On some models, the washer may beep when you press the Start button if the main door is ajar.
Turn the valves on the connected hot and cold water faucets to the completely open position, and free the hoses of any kinks or bends if you experience water flow issues with your Duet washer. Likewise, the end of the hose should not be more than 96 inches off the floor. Remove any kinks or bends from the drain hose to address a washer that doesn't drain properly, and tighten the drain hose and water hose connects to remedy leaks. As you troubleshoot the washer, press the Pause or Cancel button to stop any in-progress cycles and unplug the appliance.
Switch to high-efficiency detergent if your Duet produces excess suds. Your washer may automatically start a suds cycle -- indicated by "SUD" on the display -- to eliminate excess suds; if this happens often, switch up detergents to see if the situation remedies.
Redistribute the weight of your load, ensuring an even balance of weight throughout the drum, to remedy a Duet washer that won't spin or drain properly. Remove some items if the drum is too tightly packed, as indicated by an "F07" or "E01" error code on some Duet models.
Reduce noise and vibrations by tightening the nuts of the washer feet against the washer cabinet or placing a piece of 3/4-inch plywood underneath the washer feet and ensuring the surface is stable and level.
Run the Clean Washer cycle if your Duet includes this feature and the Clean Washer LED light blinks at the end of a cycle. This indicates that you have run 30 cycles and the appliance needs cleaning.
