TROUBLESHOOTING 41 TROUBLESHOOTING The washer is equipped with an automatic error-monitoring system to detect and diagnose problems at an early stage. If the washer does not function properly or does not function at all, check the following before you call for service. FAQs Q: Why does my washer make loud banging noises while it is filling with water? A: This is actually a problem with the plumbing in your home.
TROUBLESHOOTING Problem Possible Cause & Solution UE The load is too small. UNBALANCE ERROR • Add additional items to allow the washer to balance the load. Heavy articles are mixed with lighter items. • Always try to wash articles of somewhat similar weight to allow the washer to evenly distribute the weight of the load for spinning. The load is out of balance. • Manually redistribute the load if articles have become tangled, preventing the automatic rebalancing from working properly.
TROUBLESHOOTING 43 Noises Problem Door lock sounds when the door locks or unlocks. • Normal operation Spraying or hissing Water spraying or circulating during the cycle • Normal operation Humming or Gurgling Drain pump is pumping water from the washer at times during a cycle. Water sloshing A liquid in the balance ring around the pulsator helps the basket spin smoothly.
TROUBLESHOOTING Operation Problem Water Leaking Possible Cause & Solution Hoses are not connected correctly. • Check hoses and connectors for leaks, cracks, and splits. • Check and tighten hose connections. House drain pipes are clogged. • The washer pumps out water very rapidly. Check for water backing up out of the drain pipe during drain. If water is seen coming out of the drain, check for proper drain hose installation and check for restrictions in the drain.
TROUBLESHOOTING 45 Problem Too much detergent used. • Make sure that the suggested amount of detergent is used according to the manufacturer’s recommendations. You may also dilute the detergent with water to the maximum fill line on the compartment to avoid clogging. Use only HE (High-Efficiency) detergent. NOTE • Always use as little detergent as possible. HE (High-Efficiency) washers need very little detergent to achieve optimum results.
TROUBLESHOOTING Problem Washer is not filling properly. Possible Cause & Solution Inlet hoses may be kinked. • Check that inlet hoses are not kinked or clogged. Energy efficiency • This is a High-Efficiency (HE) washer. As a result, the water level settings for this washer may be different than for conventional washer. Insufficient water supply • Make sure that both hot and cold water faucets are turned on all the way. Washer door is open.
TROUBLESHOOTING 47 Problem Poor stain removal Possible Cause & Solution Previously set stains. Musty or mildewy odor in the washer Incorrect or too much detergent has been used. • Use only HE (High-Efficiency) detergent in accordance with the manufacturer’s instructions. Inside of the drum was not cleaned properly. • Run the Tub Clean cycle regularly. Odor Problem Odor Possible Cause & Solution Some odor is caused by the rubber attached to the washing machine.
TROUBLESHOOTING Problem Trouble connecting appliance and smartphone to Wi-Fi network Possible Cause & Solution The router frequency is not 2.4 GHz. • Only a 2.4 GHz router frequency is supported. Set the wireless router to 2.4 GHz and connect the appliance to the wireless router. To check the router frequency, check with your Internet service provider or the router manufacturer.
