A dishwasher that won’t drain can leave you with a sink full of dirty water and dishes. Understanding the common reasons a dishwasher won’t drain and knowing when to call a plumber can save you time and frustration. Beis Plumbing, serving the St. Louis area, shares expert advice on troubleshooting a dishwasher that won’t drain.
Common Reasons a Dishwasher Won’t Drain
If your dishwasher won’t drain, it could be due to several issues. According to the Angi, the most common causes include:
- Clogged or dirty filter
- Blocked drain hose
- Faulty drain pump
- Garbage disposal connection issues
- Air gap problems
Ignoring a dishwasher that won’t drain can lead to water damage and mold growth in your kitchen.
How to Troubleshoot a Dishwasher That Won’t Drain
If your dishwasher won’t drain, try these steps:
- Turn off the power to the dishwasher
- Remove and clean the filter
- Check the drain hose for blockages
- Inspect the garbage disposal connection
- Test the drain pump for proper operation
According to the EPA, fixing leaks and drainage issues promptly can save thousands of gallons of water each year. Before attempting any troubleshooting, ensure you have towels and a shallow pan ready to catch any standing water that may spill out during the process. Most drainage issues stem from food particles and grease buildup in the filter or drain hose, making regular cleaning and maintenance key to preventing future problems. If these basic troubleshooting steps don’t resolve the issue, it’s time to contact a professional plumber, as the problem may involve electrical components or require specialized tools to diagnose and repair properly.
