How to Enter Diagnostic Mode on a Kenmore Washing Machine

Kenmore washers are built by Whirlpool (110-prefix) or LG (796-prefix) — identify your builder from the model prefix, then use that brand's diagnostic procedure.

Step-by-Step: Kenmore Washing Machine Diagnostics

1
Find the model number (door frame or rear label). The 3-digit prefix before the dot identifies the manufacturer: 110 = Whirlpool, 796 = LG, 417 = Frigidaire.
2
110-prefix dial models: use the Whirlpool VMW knob sequence — counterclockwise full turn, then clockwise 3, counterclockwise 1, clockwise 1; lights flash on success.
3
796-prefix models: use LG's procedure — codes display directly (OE, IE, LE…), and SmartDiagnosis works on equipped models.
4
The tech sheet location follows the builder: inside the lower front panel (front load) or under the top panel (top load).

💡 Good to know: Searching your error code under the builder brand (Whirlpool F21 / LG OE) finds far more documentation than searching 'Kenmore'.
