Samsung Washer Not Filling With Hot Water

Introduction

A washing machine that refuses to fill with hot water can be frustrating. You rely on hot water to properly clean and sanitize your clothes, especially whites and heavily soiled items. When your Samsung washer only fills with cold water, your clothes may not be getting as clean as they should. Addressing this problem promptly can save you from re-washing loads and ensure your clothes are properly cleaned. Let’s troubleshoot why your samsung washer not filling with hot water and how to fix it.

Common Causes of samsung washer not filling with hot water

Several factors can prevent your Samsung washer from filling with hot water:

• Kinked or Blocked Water Inlet Hoses: A bent or clogged hose restricts water flow.
• Clogged Water Inlet Valve Screens: Small screens on the valve can trap sediment.
• Faulty Water Inlet Valve: The valve that controls hot water flow might be defective.
• Temperature Selection Error: You may have accidentally selected a cold water wash setting.
• Hot Water Heater Issues: The water heater itself might not be producing hot water.
• Pressure Problems: Low water pressure from your home can affect the fill.
• Washer’s Control Board Malfunction: Though rare, the control board could be sending incorrect signals.
• Incorrect Hose Connections: The hot and cold water hoses might be switched.

Symptoms Checklist

Use this checklist to accurately identify the issue:

• The washer fills, but only with cold water, even on a hot water setting.
• No water enters the washer at all when the hot water setting is selected.
• The hot water faucet in your home is producing hot water correctly.
• Error codes related to water temperature or fill errors are displayed.
• The water temperature during the wash cycle is noticeably cold.

How to Fix samsung washer not filling with hot water Step-by-Step Guide

1. Check the Hot Water Supply: Make sure your hot water heater is working and producing hot water. Test a faucet nearby to confirm.
2. Verify Water Temperature Setting: Double-check the temperature setting on your washer. Ensure it’s set to hot or warm, not cold.
3. Inspect the Hot Water Inlet Hose: Look for kinks, bends, or crushing in the hot water hose connected to the washer. Straighten any kinks.
4. Check Hose Connections: Make sure the hot water hose is connected to the “hot” water inlet on the washer and the hot water supply valve. Sometimes they’re accidentally switched.
5. Shut Off the Water Supply: Turn off both the hot and cold water supply valves behind the washing machine.
6. Disconnect the Hoses: Carefully disconnect both the hot and cold water inlet hoses from the back of the washer.
7. Inspect the Inlet Valve Screens: Inside the water inlets on the back of the washer, you’ll find small screens. Use pliers or tweezers to remove them.
8. Clean the Inlet Valve Screens: Rinse the screens under running water, using a small brush (like an old toothbrush) to remove any sediment or debris.
9. Flush the Hoses: Hold the hoses over a bucket and briefly turn the water supply valves on to flush out any sediment from the hoses themselves.
10. Reinstall the Screens and Hoses: Replace the clean screens back into the water inlets. Reconnect the hot and cold water hoses to the correct inlets on the washer.
11. Turn the Water Supply Back On: Slowly turn the hot and cold water supply valves back on. Check for any leaks at the hose connections.
12. Run a Test Cycle: Set the washer to a hot water wash cycle and observe if it fills correctly with hot water.
13. Check Water Pressure: Low water pressure can prevent proper filling. If you suspect low pressure, contact your water company or a plumber.

Fix the Issue Without Buying Parts

Often, you can resolve the issue without needing to buy new parts:

• Reset the Washer: Unplug the washer for 1-2 minutes, then plug it back in. This can sometimes reset the control board and resolve minor glitches.
• Clean the Dispenser Drawer: A clogged dispenser drawer can sometimes affect water flow. Clean it thoroughly.
• Inspect for Blockages: Look for any visible obstructions in the hoses or water inlets.
• Run a Cleaning Cycle: Some Samsung washers have a self-cleaning cycle that can help clear out mineral buildup and debris.

When Replacement Might Be Necessary

If the troubleshooting steps above don’t work, the water inlet valve might be faulty and need replacement. The cost for a water inlet valve typically ranges from $30 to $80 USD. Another possibility, though less common, is a faulty temperature sensor (around $20-$50). As a last resort, if all other components check out, the main control board could be the culprit. However, replacing the control board is a more significant repair and often more cost-effective to replace the entire machine, depending on its age and condition.

Safety Warning

• Always unplug the washing machine from the power outlet before performing any repairs.
• Turn off the water supply valves to prevent flooding.
• Be careful when handling tools to avoid injury.
• If you are uncomfortable performing any of these steps, contact a qualified appliance repair technician.
• Make sure the area around the washer is dry before plugging the machine in.

Tools You May Need

• Pliers
• Screwdrivers (Phillips and flathead)
• Small brush (old toothbrush)
• Bucket
• Towels

FAQ

Here are some frequently asked questions:

• Q: Why is my washer only using cold water even though the hot water faucet works fine?
  A: The problem is likely within the washer itself, such as a clogged inlet valve screen or a faulty water inlet valve.
• Q: How do I know if my water inlet valve is bad?
  A: If you’ve cleaned the screens and checked the hoses, but the washer still doesn’t fill with hot water, the valve might be faulty. A multimeter can be used to test its continuity, but this is a more advanced step.
• Q: Can low water pressure cause this issue?
  A: Yes, low water pressure can affect the washer’s ability to fill properly. Check your home’s water pressure.
• Q: My washer is showing an error code related to water temperature. What does this mean?
  A: An error code often indicates a problem with the temperature sensor or the water inlet valve. Consult your washer’s manual for specific error code definitions.
