Kenmore Dishwasher Error Code 6-1

Low or no water (mechanical problem)

Kenmore codesKenmore dishwasher codes

Low or no water (mechanical problem) — no water to dishwasher, bowls capturing wash water, drain loop detached, water leaking, fill valve or water line plugged, overfill switch stuck, or fill valve electrical problem.

First step from the service manual

Verify water supply is turned on and supply line adequate. Check for water siphoning. Check for debris in fill valve inlet screen. Check float switch operation.

What 6-1 means on a Kenmore dishwasher

Error code 6-1 on a Kenmore dishwasher indicates the control board detected a low-water or no-water condition during the fill cycle. The board monitors incoming water through the float switch and fill valve circuit, and when it fails to detect adequate water within the expected fill window, it triggers this fault. Root causes span mechanical and electrical sides: a plugged fill valve inlet screen, a detached drain loop causing siphoning, a stuck overfill float switch, a kinked or closed supply line, or an electrical failure in the fill valve solenoid circuit.

For homeowners, this code essentially means your dishwasher tried to fill with water but either nothing came in, or something drained it back out before the cycle could start. Common non-part scenarios include the water supply valve being closed under the sink, a drain hose that has slipped off its high-loop mount and is siphoning water out as fast as it fills, or a small screen inside the fill valve inlet that has clogged with mineral deposits or debris. In other cases, the float switch that prevents overfilling gets stuck in the raised position and tells the control board the tub is already full, stopping the fill before any water enters.

Common causes of 6-1

  1. 01

    Water supply valve closed or supply line restricted

    Wiring / connection

    If the shut-off valve under the sink is partially or fully closed, the dishwasher cannot draw enough water to satisfy the fill requirement. A kinked or undersized supply line produces the same result.

  2. 02

    Drain loop detached, causing water siphoning

    Wiring / connection

    When the drain hose loses its high-loop mount or air gap connection, water siphons back out of the tub as it fills, preventing the dishwasher from reaching the required water level. Reattaching and securing the drain hose to its proper height resolves this without parts.

  3. 03

    Clogged fill valve inlet screen

    Part replacement

    A mesh screen at the inlet of the water fill valve traps sediment and mineral deposits over time, restricting water flow enough to trigger a 6-1 fault. The screen can sometimes be cleaned, but a heavily scaled or damaged valve typically needs replacement.

  4. 04

    Stuck overfill float switch

    Part replacement

    The float assembly in the tub base rises with water level and signals the control board to stop filling. If the float is stuck in the up position due to debris or a faulty switch, the board sees a false full-tub signal and never opens the fill valve, resulting in a 6-1 code.

Frequently asked questions about 6-1

What does error code 6-1 mean on a Kenmore dishwasher?
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.
How do I fix error code 6-1 on my Kenmore dishwasher?
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.
Can I still run my dishwasher with a 6-1 error code active?
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.
How much does it cost to repair a Kenmore dishwasher showing code 6-1?
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.
Why does my Kenmore dishwasher show 6-1 even though the water is turned on?
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.
