Faulty water inlet valve (part number DD82-20019A in Samsung schematics) 6. Blocked water supply hoses from mineral deposits or sediment ## Troubleshooting Steps | Step | Action | Expected Result | |------|--------|-----------------| | 1 | Unplug machine and turn off water supply | Safety precaution | | 2 | Inspect hose connections at wall and machine | Both hoses should be straight, uncrimped | | 3 | Verify hot (red) and cold (blue) hose connections | Colors must match at both ends | | 4 | Remove and clean inlet filter screens | Clear of debris when held to light | | 5 | Check wire harness to water valve | Firm click when reconnected | | 6 | Restore power and water, run test cycle | Error should clear if issue resolved | If error persists after these steps, proceed to technician assistance. ## When to Call a Technician Contact Samsung authorized service when:
