Kenmore Dishwasher Error Code 6-1

Code 6-1 means the dishwasher detected low or no water during the fill cycle. The control board monitors incoming water and trips this fault when adequate water is not present within the expected time. Causes range from a closed supply valve or siphoning drain hose to a clogged fill valve screen or a stuck float switch.

No. A 6-1 fault means the dishwasher is not filling with water, so running a cycle will not clean dishes and could cause the heating element to run dry if any residual water is present. Resolve the water supply or fill valve issue before resuming normal operation.

If the supply is confirmed on and the code persists, the most likely culprits are a clogged fill valve inlet screen blocking flow, a drain hose positioned too low causing siphoning, or a float switch stuck in the raised position signaling a false full-tub condition. Check the float first since it requires no tools, then inspect the fill valve screen, then test the fill valve solenoid for continuity with a multimeter.

Start by confirming the water supply valve under the sink is fully open and the supply line is not kinked. Next, check that the drain hose is mounted in a proper high loop or connected to an air gap to prevent siphoning. Then remove the fill valve inlet screen and rinse out any sediment. Finally, locate the float in the bottom of the tub, lift it by hand, and listen for a click from the switch beneath it. If the float moves freely and the supply is confirmed good, the fill valve solenoid or its wiring may need testing with a multimeter.

If the fix is a repositioned drain hose or an open supply valve, the cost is nothing. A replacement water inlet fill valve typically costs between $20 and $60 for the part, and is a moderate DIY repair requiring the lower access panel to be removed. A float switch assembly runs $10 to $30. If you hire a technician, expect $100 to $200 total including the service call and parts, depending on which component is faulty.
