The F6 error code on a Kenmore dishwasher means the appliance is not receiving adequate water supply. The dishwasher is designed to detect water flow at the start of a cycle, and if it cannot fill within a set time window, it will display the F6 error and stop the cycle to prevent the pump from running dry.
What Causes the Kenmore Dishwasher F6 Error?
- Water supply valve under the sink is turned off or partially closed
- Kinked or pinched water supply hose
- Clogged water inlet valve screen/filter
- Faulty water inlet valve not opening properly
- Low home water pressure (below 20 PSI)
- Frozen water supply line (in cold climates)
Step-by-Step Troubleshooting
- Check that the water supply valve under the sink is fully open.
- Inspect the water supply hose for kinks or crushing.
- Turn off the water supply, disconnect the inlet hose from the valve on the dishwasher, and inspect the screen filter for debris. Clean if clogged.
- Check your home water pressure — if other faucets have low flow, contact your water utility.
- If all of the above check out, the water inlet valve itself may be defective and needs replacement.

A defective water inlet valve requires professional replacement. This component controls water flow into the dishwasher and is not a user-serviceable part.
