Does this guide apply to your appliance?
Match the brand, device type and complete display code. The same code can mean something different on another product family or market; a series name does not confirm every model in that series.
No exact model number is recorded here. Confirm the code in your appliance manual before following a check.
Likely causes
- Kinked or damaged inlet hose obstructing water flow
- Water supply turned off or inadequate water pressure
- Faulty water inlet valve possibly due to mineral buildup or wear
What to try
Inspect and Clear the Inlet Hose
Easy- Turn off the dishwasher and disconnect it from the power source.
- Locate the water inlet hose at the back of the dishwasher.
- Check for any kinks, bends, or visible damage along the hose.
- Straighten any kinks or replace the hose if damaged.
- Ensure the hose is properly connected and free of obstructions.
- Reconnect power and run a test cycle to check if error clears.
Verify Water Supply and Pressure
Easy- Ensure the water supply valve to the dishwasher is fully turned on.
- Check that there is adequate water pressure from the supply line.
- If water pressure seems low, try using water from other taps to confirm the problem is localized.
- If the problem persists, contact your water supplier or a plumber.
- After confirming proper water supply, reset and run the dishwasher to verify error resolution.
