Hot water conundrum: the curious case of the samsung washer that refuses cold

If your Samsung washer has suddenly started using only hot water, it can be a frustrating and inconvenient issue. Understanding the underlying causes and implementing effective solutions is crucial to restore your washer to its normal functioning.

Common Causes of Hot Water Only Issue

• Faulty Temperature Sensor: The temperature sensor monitors the water temperature and sends signals to the control board. A damaged or malfunctioning sensor can provide incorrect readings, causing the washer to use hot water exclusively.
• Defective Inlet Valve: The inlet valves control the flow of hot and cold water into the washer. A faulty inlet valve can stick or malfunction, preventing the cold water from entering the washer.
• Control Board Malfunction: The control board is the brain of the washer, controlling various functions, including water temperature. A malfunction in the control board can disrupt the temperature regulation process.
• Blocked Cold Water Line: A blockage or kink in the cold water supply line can restrict the flow of cold water, leading to the washer using only hot water.
• Incorrect Water Temperature Setting: Sometimes, the issue may be as simple as an incorrect water temperature setting on the washer control panel. Ensure that the desired water temperature is selected.

Troubleshooting and Solutions

1. Check Temperature Sensor:

• Locate the temperature sensor, usually near the water inlet valves.
• Disconnect the sensor and check for continuity using a multimeter.
• Replace the sensor if it shows no continuity.

2. Inspect Inlet Valves:

• Turn off the water supply and disconnect the inlet valves.
• Check for any visible damage or debris.
• Use a multimeter to test the continuity of the valves.
• Replace faulty inlet valves.

3. Reset Control Board:

• Unplug the washer and wait for a few minutes.
• Plug the washer back in and start a rinse cycle.
• If the issue persists, consider replacing the control board.

4. Inspect Cold Water Line:

• Check the cold water supply line for any kinks or blockages.
• Straighten or replace the line if necessary.
• Ensure the cold water faucet is fully open.

5. Verify Water Temperature Setting:

• Check the washer control panel and confirm that the correct water temperature is selected.
• If needed, adjust the setting to the desired temperature.

Additional Tips

• Run a hot water cycle to flush out any sediment or debris that may be clogging the inlet valves.
• Clean the washer’s detergent dispenser and bleach dispenser regularly to prevent buildup.
• Use a water softener if you have hard water, as mineral deposits can interfere with the water temperature sensor.

Wrapping Up

Identifying and addressing the underlying cause of why your Samsung washer is only using hot water is essential to restore its normal operation. By following the troubleshooting steps outlined above, you can effectively resolve the issue and ensure your washer delivers the desired water temperature for your laundry needs.
