6-1
Water Fill Fault
If your KitchenAid Dishwasher is displaying the error code 6-1, the control board has detected a fault identified as "Water Fill Fault". Understanding the root cause helps you avoid an unnecessary service call.
Owner's Summary
Your KitchenAid dishwasher cannot fill with water. Start with the water supply valve under the sink — it should be fully open. This simple check resolves the majority of 6-1 errors at no cost.
Symptoms
KitchenAid dishwasher not filling with water, 6-1 error code displayed
Common Causes
- Water supply valve closed under sink
- Clogged inlet valve screen
- Failed water inlet valve solenoid
- Low water pressure below 20 PSI
How to Fix
- 1 Open water supply valve fully
- 2 Clean inlet valve screen
- 3 Test water pressure at nearby tap
- 4 Test inlet valve solenoid resistance and replace if open or shorted
Tools You'll Need
Most of these fixes need only basic hand tools. If your repair requires opening electrical housings or testing live components, a multimeter and basic electrical safety knowledge are essential — when in doubt, call a technician.
Technical Explanation
6-1 on KitchenAid indicates the control board's fill circuit did not receive fill confirmation from the pressure switch or float switch within the programmed timeout after the inlet valve solenoid was energized.
Is It Safe to Keep Using?
No risk to the appliance.
Technician's Pro Tip
KitchenAid dishwashers installed in newly renovated kitchens sometimes have the supply valve flow restrictor installed too aggressively — this limits pressure below the minimum required for the inlet valve to open fully. Check the supply line fitting for a flow restrictor if pressure tests are borderline.
