A common symptom of a faulty drive belt is a washer that is making loud noises during operation. The drive belt can dry out over time, causing it to crack and eventually break off. This needs to be replaced to fix the washer. A loose drive belt can also cause the washer to make loud noises. This cannot be tightened, and needs to be replaced.
A faulty drive motor causes the washer not to agitate and must be replaced. The drive motor is usually inspected for signs of physical damage, such as burning or breaking. The problem is, however, not as common as a broken drive belt. Appliance owners are advised to call an appliance repair person to inspect and replace the drive motor if they suspect this to be the problem.
Lastly, the drive pulley is a commonly replaced washer part and causes the washer not to spin if faulty. Common problems with drive pulleys include damage, seizing and wear and tear. The drive pulley should be removed, inspected for damage and replaced if needed to fix the washer problem.Learn more about Washers & Dryers
