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.
Noises You Might Hear

load.

laundry additives to add to the
wash load.
Rattling and clanking

Foreign objects, such as keys,
coins, or safety pins may be in

for foreign objects. If noise continues after
washer is restarted, call for service.

Heavy wash loads may produce a
thumping sound.
