Whirlpool Dishwasher Error Code F10E5

F10E5 indicates a diverter leak fault, meaning the control has detected a problem in the diverter sensor circuit or evidence of a leak at the diverter seal. The diverter directs water flow to different wash zones, and this code appears when the sensor circuit shows abnormal readings due to corrosion, loose connections, or water intrusion. The dishwasher will typically stop operation to prevent additional damage to electrical components.

Continuing to run the dishwasher with an active F10E5 code is not recommended. A leaking diverter seal can allow water to contact electrical components, which increases the risk of further damage or an electrical hazard. Resolve the fault before resuming normal use.

If only cleaning corroded connections or reseating a loose connector is needed, out-of-pocket costs are minimal. If the diverter assembly requires replacement, parts costs typically range from $50 to $150 depending on the model, with professional labor adding $100 to $200 or more. Getting a diagnosis first helps confirm whether a full replacement is actually necessary before committing to the higher repair cost.

If the cause is a loose connector or light corrosion, a knowledgeable DIYer can address F10E5 by cleaning connections and reseating connectors after disconnecting power. If the diverter seal is leaking or the motor assembly shows significant water damage, replacing the diverter assembly is more involved and may warrant a professional technician. Always disconnect power before inspecting any internal components.

Resetting the dishwasher by cutting power may temporarily clear the code, but it will return if the underlying problem is not corrected. The fault is generated by a real condition in the diverter sensor circuit or at the diverter seal, so a reset alone is not a fix. Address the root cause first, then reset the control to confirm the code does not return.
