Dishwasher Not Draining: Common Causes and Troubleshooting
A dishwasher that doesn’t drain properly can be a frustrating problem. It can leave your dishes dirty, create a foul odor, and even lead to water damage. Fortunately, most dishwasher drainage issues can be resolved with some basic troubleshooting steps.
This guide will help you understand the common causes of a dishwasher not draining, provide step-by-step instructions for fixing the problem, and highlight potential safety concerns.
Common Causes of Dishwasher Not Draining
A dishwasher that doesn’t drain properly can be caused by a variety of factors. Some of the most common reasons include:
- Clogged drain hose:Food particles, grease, and other debris can accumulate in the drain hose, restricting water flow.
