Flushing the supply line of your refrigerator ensures that any impurities or debris are removed, allowing for clean water to reach the ice maker. Follow these steps to flush the supply line properly:
Caution:
Please read our safety information before attempting any testing or repairs.
Before disconnecting the water line, unplug the refrigerator to avoid an electrical shock hazard.
Steps to Flush the Supply Line:
- Turn Off the Water Supply:
- Locate the water source, usually found under the kitchen sink or behind the refrigerator.
- Turn off the water supply valve to stop the flow of water to the refrigerator.
- Disconnect the Supply Line:
- Locate the water inlet valve on the back of the refrigerator.
- Use a wrench to disconnect the supply line from the inlet valve.
- Place the end of the supply line into a bucket to catch any water.
- Flush the Supply Line:
- Turn on the water supply at the source to flush out any debris or impurities in the supply line.
- Allow the water to flow through the line and into the bucket until it runs clear.
- Turn off the water supply once the line is thoroughly flushed.
- Reconnect the Supply Line:
- Reconnect the supply line to the water inlet valve on the refrigerator.
- Ensure the connection is secure but do not overtighten to avoid damaging the fittings.
- Flush the Internal Tubing:
- Disconnect the internal water line(s) from the inlet valve.
- Allow any remaining water in the lines to drain into a bucket.
- Follow the internal line up the back of the freezer, removing any fasteners holding it in place.
- Disconnect the internal line from the connector leading into the freezer.
- Clean the Internal Tubing:
- Take the internal tubing to your sink.
- Squeeze a few drops of liquid dish soap into the tube.
- Hold one end of the tube under warm running water and allow the other end to drain into the sink.
- Continue flushing with water until no more soap bubbles appear. Repeat if necessary.
- Alternatively, replace the tubing with “food grade” quality tubing suitable for potable water if it does not come clean.
- Reconnect the Internal Tubing:
- Reconnect the internal tubing to the connector leading into the freezer and secure any fasteners.
- Reconnect the other end to the inlet valve on the refrigerator.
- Turn On the Water Supply:
- Turn the water supply back on at the source.
- Check all connections for leaks.
- Plug the refrigerator back in and move it back into place.
- Flush the System:
- It may take a couple of ice-making cycles before any taste improvement is noticeable. Discard the first few batches of ice made after flushing the lines.
By following these steps, you can ensure that your refrigerator’s supply line is free of debris and impurities, providing clean water for ice production.
