One common issue we hear about is, “My dishwasher is not draining, what should I do?” While we don’t handle appliance repairs, dishwashers are connected to your home’s plumbing, and that’s right up our alley. If your dishwasher’s drainage woes are due to a plumbing issue, we’re the ones you should call.

When It’s Not an Appliance Issue

First off, it’s crucial to establish whether the problem lies within the dishwasher appliance itself or if it’s related to your home’s plumbing. If the drainage issue is due to a malfunctioning pump, sensor, or some other internal component, you’ll need to contact an appliance repair service.

Signs that Plumbing Could Be the Issue

  • Slow Draining Sink: If your kitchen sink is taking its sweet time to drain, it could be an indicator that there’s a blockage in the pipes that are also connected to your dishwasher, causing it not to drain.
  • Water Backflow: Water backing up into your sink from the drain when the dishwasher is running? This is a clear sign that there’s a clog in the shared drain line.
  • Bad Odor: Smelling something foul emanating from your dishwasher or sink? This can point to food particles or other debris causing a blockage in the drain, affecting the drainage of your dishwasher.
  • Dishwasher Drain Line Clog: Sometimes, the clog could be in the dishwasher drain line connecting the dishwasher to the kitchen drain line. This would also cause your dishwasher not to drain and is a plumbing issue we can handle.

How to Fix the Issue

  • Clean the Air Gap: If your home has an air gap installed near the faucet, it could be clogged. Cleaning it might resolve your issue.
  • Check the Garbage Disposal: Often, the dishwasher drain is connected to the garbage disposal. Run your disposal to clear any food debris that might be blocking the drain.
  • Clean the Sink Drain: For minor sink clogs, a mixture of vinegar and baking soda might do the trick. Pour the baking soda down the drain, followed by vinegar. Let it sit for at least 15 minutes, then run hot water.
  • Clear the Dishwasher Drain Line: To clear a blocked dishwasher drain hose, disconnect it, then run water through it outdoors. If the water doesn’t flow freely, use forced air or a straightened coat hanger to remove the clog. If you can’t clear it, consider replacing the drain hose.

If all else fails and you’re still experiencing drainage issues, don’t hesitate to call us. At Instant Plumbing and Rooter, we’re experts at resolving these types of plumbing issues. We’ll evaluate your system and get everything back to working condition.

Frequently Asked Questions

Q: How do I know if my dishwasher’s drainage problem is a plumbing issue?

A: If your kitchen sink is also draining slowly or you notice water backing up into your sink when the dishwasher is running, these are strong indicators that it could be a plumbing issue. Foul odors coming from the dishwasher or sink can also suggest a drain clog.

Q: What is the air gap and how do I clean it?

A: The air gap is a small device that sits near your kitchen faucet and prevents sink water from flowing back into the dishwasher. If you think it might be clogged, remove the cover and clean it out using a small brush to remove debris.

Q: Can I use home remedies to clear minor sink clogs?

A: Yes, a mixture of vinegar and baking soda can sometimes clear minor clogs. Pour the baking soda down the drain first, followed by vinegar. Let the mixture sit for at least 15 minutes, and then run hot water. However, for persistent clogs, it’s advisable to call a professional.

Q: Is the dishwasher drain line something I can check myself?

A: The dishwasher drain line connects the dishwasher to the kitchen drain line. While you can visually inspect the line for kinks or apparent clogs, diagnosing issues within the line usually requires professional equipment and expertise.

Q: If I’m still experiencing issues, what should be my next step?

A: If you’ve tried all the troubleshooting steps and you’re still facing issues, it’s time to call a professional.
