SAFE SERVICING PRACTICES - ALL APPLIANCES
To avoid personal injury and/or property damage, it is important that Safe
Servicing Practices be observed. The following are some limited examples of
safe practices:
1. DO NOT attempt a product repair if you have any doubts as to your ability to
complete it in a safe and satisfactory manner.
2. efore servicing or moving an appliance:
 Remove the power cord from the electrical outlet, trip the circuit breaker to
the OFF position, or remove the fuse.
 Turn off the gas supply.
 Turn off the water supply.
3. Never interfere with the proper operation of any safety device.
4. USE ONLY REPLACEMENT PARTS CATALOGED FOR THIS APPLIANCE.
SU STITUTIONS MAY DEFEAT COMPLIANCE WITH SAFETY
STANDARDS SET FOR HOME APPLIANCES.
5. GROUNDING: The standard color coding for safety ground wires is GREEN,
or GREEN with YELLOW STRIPES. Ground leads are not to be used as current
carrying conductors. It is EXTREMELY important that the service technician
reestablish all safety grounds prior to completion of service. Failure to do so
will create a hazard.
6. Prior to returning the product to service, ensure that:
 All electrical connections are correct and secure
 All electrical leads are properly dressed and secured away from sharp
edges, high-temperature components, and moving parts
 All non-insulated electrical terminals, connectors, heaters, etc. are
adequately spaced away from all metal parts and panels
 All safety grounds (both internal and external) are correctly and securely
connected
 All panels are properly and securely reassembled

WHAT'S NEW
ÖCOLLAPSIBLETOWER- Single wash arm on low end models with collaspsible tower that is molded into the
spray arm. This tower retracts completely into the lower arm giving added area in the lower rack.
ÖVENT COVER- The vent cover has the gasket molded into the cover to prevent water leaks.
ÖPUMPANDMOTORASSEMBLY-Thewashpumpandmotorareinonepieceandisnotrepairable.Thenew
design motor does not have nor need a seal to prevent water leaks. In the end of this motor is a small circuit
board that is designed to make sure that the motor will always start in the proper direction. This new motor is
mounted with a new mounting bracket that only requires two screws.
ÖSANITIZERINSE-On thehigherendmodels, asanitizerinsesetting hasbeenaddedand therinsetemperature
