Whirlpool Washer, Dryer Error Code LP

LP is a lid switch fault code that appears during the service routine reset procedure on Whirlpool washers. It indicates the control board has detected a failure in the lid switch safety circuit, which monitors whether the lid is open or closed. The code is specific to the diagnostic reset sequence and signals that the lid switch system needs to be inspected and the reset properly completed before the washer will operate normally.

The LP code is cleared specifically through the two-step S6 service keypad reset procedure, not a standard power cycle. If the underlying lid switch problem is still present when you complete the reset, the code is likely to return after the next spin cycle. Addressing the root cause before resetting gives the best chance of permanently clearing the fault.

If only the lid switch assembly needs replacement, parts typically range from around $15 to $50 depending on the specific model, with labor adding $75 to $150 if a technician is hired. Replacing a lid strike is generally a lower cost repair, often under $20 for the part. A control board replacement, if needed, is significantly more expensive, with parts and labor potentially reaching $200 to $400 or more.

Start by completing the correct reset procedure: press the hidden S6 service keypad within 60 seconds of entering diagnostic mode, then press S6 again within 10 seconds. If the code returns after the reset, inspect the lid switch assembly, wiring harness, and lid strike for damage. Replace any faulty components and repeat the reset sequence to clear the fault.

The lid switch is a safety component designed to stop the spin basket from rotating when the lid is open. With an LP fault active, the control board may restrict spin operation to protect against that hazard. Running the washer while this fault is unresolved is not recommended, as the safety system may not be functioning reliably.
