GE Dishwasher Error Code F37

Diverter feedback error.

GE codesGE dishwasher codes

Diverter feedback error.

First step from the service manual

Check that diverter sensor plug (red) is properly connected to the diverter. Check water level: if low, correct water level issue. Use clear door, run Operate Loads - Circulation Pump Test. If position never changes when selecting each wash area, replace the diverter. If position changes every 5- to 15-seconds when selecting a single wash area, replace the diverter and DC harness.

What F37 means on a GE dishwasher

The F37 error code indicates the control board detected a diverter feedback error. The diverter is a motorized component that directs water flow to different wash zones inside the dishwasher. The control board monitors the diverter's position through a sensor and expects to see position changes as wash areas are cycled. When the sensor feedback does not match expected behavior, or when no position change is detected at all, the board throws F37. Low water level can also trigger this code because insufficient water prevents the diverter from operating correctly.

For homeowners, this error means the dishwasher's water-directing valve is either not moving when it should or is reporting its position incorrectly. Think of the diverter as a traffic controller that routes water to the upper rack, lower rack, or other wash zones at different points in the cycle. If it gets stuck, loses its connection to the control board, or fails mechanically, the dishwasher cannot confirm water is reaching the right areas and will halt with F37.

The most common starting points are a disconnected diverter sensor plug (the red connector at the diverter) and a low water level condition. If those are ruled out, the diverter motor itself or the DC wiring harness connecting the diverter to the control board are the likely culprits.

Common causes of F37

  1. 01

    Disconnected or loose diverter sensor plug

    Wiring / connection

    The red sensor plug at the diverter can work loose over time from vibration. When the connection is interrupted, the control board receives no position feedback and triggers F37.

  2. 02

    Low water level in the dishwasher

    Wiring / connection

    If the tub does not fill to the correct level, the diverter lacks sufficient water pressure to operate and change positions, causing the control board to log a feedback error.

  3. 03

    Failed diverter motor

    Part replacement

    If the diverter position never changes during a circulation pump test across all wash area selections, the diverter motor has failed and the entire diverter assembly needs replacement.

  4. 04

    Faulty diverter and DC wiring harness

    Part replacement

    If the diverter position cycles every 5 to 15 seconds when a single wash area is selected rather than holding steady, both the diverter and the DC harness connecting it to the control board are defective and must both be replaced.

Frequently asked questions about F37

What does the F37 error code mean on a GE dishwasher?
F37 means the control board detected a diverter feedback error. The diverter routes water to different wash zones, and the board monitors its position through a red sensor plug. F37 fires when the sensor reports no movement, unexpected movement, or when water level is too low for the diverter to function. Start by checking that the red diverter sensor plug is seated firmly and verify the dishwasher is filling with enough water.
How do I fix the F37 error code on a GE dishwasher?
Begin by reseating the red sensor plug on the diverter and checking that the dishwasher is filling to the correct water level. If those checks pass, run a circulation pump test using the Operate Loads function while watching the wash zone selections through the clear door. If the diverter position never changes across all selections, replace the diverter. If the position keeps cycling every 5 to 15 seconds while holding a single wash area selection, replace both the diverter and the DC harness. The harness replacement requires some comfort working around wiring inside the appliance.
Can I still use my GE dishwasher if it is showing F37?
Running the dishwasher with an active F37 code is not recommended. The diverter controls which wash zones receive water, so if it is stuck or not responding, dishes will likely not be cleaned properly and water may not reach all areas of the tub. Continuing to run cycles in this state can also stress the circulation pump. Resolve the error before returning to normal use.
How much does it cost to fix an F37 error on a GE dishwasher?
If the fix is just reseating the diverter sensor plug or correcting a water fill issue, there is no parts cost. Replacing the diverter assembly typically costs between $40 and $120 for the part depending on the specific model. If both the diverter and the DC harness need replacement, budget an additional $20 to $60 for the harness. Professional labor for this repair generally runs $100 to $200 depending on your area, making it a reasonable DIY repair for someone comfortable working inside the appliance.
Why does my GE dishwasher keep cycling through wash zones when I select just one during the F37 test?
If the diverter position changes every 5 to 15 seconds while you hold a single wash area selection during the Operate Loads circulation pump test, both the diverter and the DC harness are faulty. The harness is sending or receiving incorrect signals that cause the diverter to keep repositioning instead of staying locked on the selected zone. Replacing only the diverter without also replacing the DC harness in this scenario will not resolve the F37 code.
