A Whirlpool Duet washer that is not agitating can be fixed by replacing the motor coupling, tightening the drive belt or changing the drive motor. Appliance owners who are not experienced in fixing Whirlpool washers are advised to contact a qualified appliance repair person to fix the problem.
A failed coupling motor is a common cause for a washer that does not agitate. The component connects the washer transmission and motor. This is a safety feature designed to protect the transmission and motor, and fails if the washer is overloaded. The coupling should be checked for damage and replaced if faulty to fix the problem.
Next, the drive belt should be checked for a washer that is not agitating. The drive belt moves the pulleys to allow the washer to agitate. This can break or become loose through wear and tear. The drive belt needs to be tightened if loose and replaced if broken to fix the problem.
Lastly, a defective drive motor causes a washer not to agitate, although this is a less common problem. Appliance owners are advised to inspect the drive motor as a last resort. The motor should be inspected for signs of burning or physical damage and replaced if needed to fix the problem.
