Signs Your Dishwasher Water Line May Need to Be Replaced
Dishwashers may make our lives easier, but if there is an issue with the dishwasher water line, it can cause headaches for any homeowner. To avoid this situation, look for these signs that your dishwasher water line may need to be replaced.
Common Signs You May Need a Dishwasher Water Line Replacement
1. Dishwasher Isn’t Filling With Water
If your dishwasher doesn't fill with water, the issue may stem from a variety of sources, but a bad water line may be the true culprit. If there's no water at all, try these troubleshooting steps first:
- Make sure that the water inlet hose is connected properly and that its valve is in the open position.
- If the hose is hooked up correctly and there are no kinks, it should fix the problem.
However, if the dishwasher still doesn't fill with water and the other parts of the appliance have been examined, it may be time to replace your water line.
2. The Water Connection to Your Dishwasher Is Frozen
A frozen pipe can lead to major long-term complications, and this is true for your dishwasher water line as well. If water isn't flowing freely from your line, that could mean that it's frozen. It's important to remedy this issue before the pipe bursts or results in damage to your plumbing infrastructure. If your water line is frozen, it may be necessary to replace it. You also want to check your dishwasher drain to determine if it's frozen as well.
Note: The risk of a dishwasher water line freezing is limited to pipes that are located along outside walls in uninsulated or unheated areas.
3. Water Is Leaking Out of the Dishwasher
If you see water coming from under your dishwasher, the first thing you should do is check your water line:
- Ensure that its connections are tight and secure.
- Work out any kinks that might be in the hose.
If this doesn't fix the problem, there could be a hole in the water line, which should be replaced immediately. Leaks not only cost a significant amount of money in wasted water, but they can also require extensive repairs to recover from the water damage. You might also want to try cleaning out your dishwasher to make sure the drain isn’t clogged and overflowing.
4. The Water Line Hose Has Cracks or Bulges
Take a look at your dishwasher water line. Do you notice any visible signs of damage? If you see any of the following, it means the line is weakened and could fail at any moment:
- Cracks
- Bulges
- Worn areas
- Folds
Replace lines that look like this as soon as possible to avoid a burst line.
How To Replace The Dishwasher Water Supply Line
Can you replace a water line on a dishwasher yourself? Yes, if you’ve got some DIY skills. Here’s how:
- Turn off the water supply. Typically, the shutoff valve is under the sink.
- Disconnect the old supply line. Use an adjustable wrench to unscrew the line from both the dishwasher and the shutoff valve.
- Remove the old line. Pull it out from under the sink and behind the dishwasher.
- Install the new line. Attach one end to the dishwasher inlet and the other to the shutoff valve. Hand-tighten first, then use a wrench to snug it slightly without overtightening..
- Check for kinks. The line should be unobstructed behind the dishwasher.
- Turn the water back on and test the dishwasher. Open the shutoff valve and run a short cycle to check for leaks.
