TROUBLESHOOTING TROUBLESHOOTING Before Calling for Service 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 45 Error Messages Problem Possible Cause & Solution Water supply faucets are not fully open. INLET ERROR • Make sure that the water faucets are fully open. Water inlet hoses are kinked, pinched, or crushed. • Make sure that the hoses are not kinked, pinched or crushed behind or under the washer. Be careful when moving the washer during cleaning or maintenance. Water inlet filters are clogged. • Clean the inlet filters. See MAINTENANCE. Water supply pressure to faucet or house is too low.
TROUBLESHOOTING Problem Possible Cause & Solution svd Oversudsing of detergent OVERSUDSING DETECTION • Do not add more than the manufacturer’s recommended amount of detergent. • To remove suds, turn the washer off then back on, then run the Rinse+Spin cycle. • If too many suds are detected during spinning, the washer stops to help prevent leaking. PF Power failure or inadequate electrical service may have occurred during operation.
TROUBLESHOOTING 47 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 49 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 51 Problem Staining Possible Cause & Solution Bleach or softener dispensed too soon. Bleach or softener was added directly to the wash load in the drum. • Always use the dispensers to ensure that laundry products are properly dispensed at the right time in the cycle. Washer was not unloaded promptly. • Always remove items from the washer as soon as possible after the cycle is completed. Clothes were not properly sorted.
TROUBLESHOOTING ezDispense Problem Refill Alarm continues to display when detergent/ softener is added. Possible Cause & Solution Detergent/softener has built up on the fluid level sensor. • Open the reservoir covers and clean the insides of the ezDispense reservoirs with warm water. Use a soft brush to remove any residue. If the Refill Alarm is displayed continuously, call for service. The amount of detergent/softner is not enough for the sensor to detect.
