What uF means on a Kenmore dishwasher

The uF error code on a Kenmore dishwasher signals an internal malfunction that the control board has detected but cannot resolve automatically. Because Kenmore dishwashers in this product line are manufactured by Electrolux, the uF code falls under Electrolux diagnostic protocols. The code is not tied to a single, narrowly defined component failure; rather, it serves as a general fault indicator that something within the dishwasher's operating systems has moved outside of acceptable parameters.

The malfunction flagged by the uF code could involve the control board itself, a sensor circuit, the wiring harness, or another electronic component that communicates with the main board. Because the available data does not isolate the fault to a specific resistance value, voltage threshold, or named subcomponent, the range of possible root causes is broader than with more specific error codes. This makes independent diagnosis more challenging without access to specialized service tools or wiring diagrams.

Given the general nature of this fault code and the instruction to contact Electrolux Customer Service at 1-800-944-9044 as the first diagnostic step, this error is best treated as one that requires professional evaluation. Attempting to clear the code through a reset may temporarily suppress the display, but if an underlying fault exists, the code is likely to return. A qualified technician can connect diagnostic equipment to identify the specific system involved and determine whether repair or component replacement is warranted.

Common causes of uF

  1. 01

    Control Board Fault

    Part replacement

    The main control board may have experienced an internal failure or communication error, triggering the uF code. Signs include the error appearing without any obvious external cause and the dishwasher failing to start or complete cycles.

  2. 02

    Wiring Harness or Connector Issue

    Wiring / connection

    A loose, corroded, or damaged connector in the wiring harness can cause the control board to detect an out-of-range signal and log a general fault code. Inspect visible wiring connections for signs of burn marks, corrosion, or disconnection.

  3. 03

    Faulty Sensor Circuit

    Part replacement

    A sensor tied to one of the dishwasher's operating systems, such as temperature or water level, may have failed and sent an invalid signal to the control board. This type of fault often causes the uF code to appear mid-cycle.

  4. 04

    Power Supply Irregularity

    Wiring / connection

    A brief power surge or voltage irregularity can trigger a general fault code on dishwasher control boards. If the uF code appeared following a power event, a reset may resolve it, though recurring codes indicate a deeper issue.

  5. 05

    Software or Firmware Glitch

    Wiring / connection

    The control board's firmware can occasionally log a fault code due to a transient software error. This is typically a one-time occurrence, and a hard reset by disconnecting power for several minutes may clear it.

Frequently asked questions about uF

What does uF mean on a Kenmore dishwasher?
The uF code on a Kenmore dishwasher indicates a general internal malfunction detected by the appliance's control system. It does not point to a single specific component but signals that something within the dishwasher's electronics or operating systems is outside normal parameters. Because Kenmore dishwashers in this line are built by Electrolux, the code falls under Electrolux diagnostics. Contacting Electrolux Customer Service at 1-800-944-9044 is the recommended first step.
Can I fix the uF error code on my Kenmore dishwasher myself?
Some uF errors may be caused by a transient power glitch and can be cleared by disconnecting power to the dishwasher for several minutes and then restoring it. However, if the code returns after a reset, the fault is likely hardware-related and requires a technician's diagnosis. Because the uF code covers a broad range of possible malfunctions, professional service is the safest path to a lasting repair.
Is it safe to use my Kenmore dishwasher when the uF code is showing?
It is generally not advisable to continue operating the dishwasher while an active fault code is displayed. The uF code indicates the appliance has detected an abnormal condition, and running it could worsen an existing problem or prevent the dishwasher from completing cycles properly. Power off the unit and contact Electrolux Customer Service at 1-800-944-9044 before attempting further use.
How much does it cost to repair a Kenmore dishwasher showing the uF error?
Repair costs for a uF error can vary widely depending on which component is at fault. A simple wiring fix or reset may cost little to nothing, while control board replacement can range from $150 to $400 or more including parts and labor. A technician's diagnostic visit alone typically runs $75 to $150, which is often applied toward the total repair cost.
Will resetting my Kenmore dishwasher clear the uF error code?
A power reset, done by unplugging the dishwasher or turning off its circuit breaker for a few minutes, may clear the uF code if the fault was caused by a temporary software or power issue. However, if an underlying hardware problem exists, the code will likely return once the dishwasher is used again. A persistent uF code after resetting should be evaluated by a qualified technician.
