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, blocked, or damaged inlet hose restricting water flow.
- Faulty water inlet valve preventing water from entering the dishwasher.
- Water supply turned off or inadequate water pressure.
What to try
Inspect and Straighten the Inlet Hose
Easy- Turn off the water supply to the dishwasher.
- Locate the inlet hose connecting the dishwasher to the water supply.
- Check the hose for kinks, bends, or visible damage that might restrict water flow.
- Straighten any kinks or replace the hose if damaged.
- Turn the water supply back on and check if the error clears.
Ensure Water Supply is On and Supply Line is Clear
Easy- Locate the water supply valve for the dishwasher and ensure it is fully open.
- Observe water flow from the supply line to confirm adequate pressure.
- If water flow is insufficient, check for any plumbing issues in the supply line.
- Once confirmed, run a dishwasher cycle to see if the error clears.
