Why Your Dishwasher Won’t Drain: When to Call a Pro?

Ever had that sinking feeling when your dishwasher won’t drain, leaving you with a pool of murky water and a stack of dirty dishes staring back at you? It’s a frustrating situation that can disrupt your daily routine and leave you wondering what to do next. But fear not, because in this article, we’ve got your back! We’re here to guide you through the troubleshooting process and get your dishwasher back up and running in no time.

Check the Garbage Disposal

When your dishwasher won’t drain, the problem might be with the garbage disposal. It’s connected to the dishwasher drain to prevent food particles from clogging the pipes. Sometimes the connection can get blocked, causing water to back up in the dishwasher.

To check:

  • Turn off the disposal and ensure it’s not clogged.
  • Look for any food debris or obstructions in the disposal.
  • Run water to see if it drains properly.

If the garbage disposal is clear and the dishwasher still won’t drain, you might need to explore other factors causing the issue.

Inspect the Drain Hose

When a dishwasher won’t drain, one common culprit to investigate is the drain hose. This hose is responsible for carrying the wastewater out of your dishwasher and into the plumbing system. Here’s what you can do to inspect it:

  • Start by disconnecting the drain hose from the sink or garbage disposal.
  • Check for kinks, bends, or blockages in the hose.
  • Ensure the drain hose is not clogged with food particles or debris.
  • Run water through the hose to see if it flows freely.

If the drain hose is clear, you can move on to other potential causes of the drainage issue.

Remember, a blocked drain hose can prevent your dishwasher from draining properly, so taking the time to inspect it thoroughly can help you identify and resolve the problem.

Clean the Filter

When your dishwasher won’t drain, a clogged filter could be the culprit. Here’s what to do:

  • Locate the filter at the bottom of the dishwasher.
  • Remove the filter according to your dishwasher’s manual.
  • Check for debris like food particles or soap scum.
  • Clean the Filter thoroughly under running water.
  • Reassemble and test the dishwasher to see if the issue is resolved.

Remember, a dirty filter can hinder drainage, so regular cleaning is essential for proper dishwasher performance.

Unclog the Drain

When a dishwasher won’t drain, the problem often lies with a clogged drain. Here are steps to Unclog the Drain:

  • Remove the bottom rack to access the drain.
  • Check for any visible blockages or debris that may be obstructing the drain.
  • Use a sponge or cloth to remove any excess water in the dishwasher to prevent spills.
  • Inspect the drain hose for kinks or clogs that may be restricting water flow.

By following these steps, you can effectively address the issue of a dishwasher not draining properly.
