How to Unblock an Integrated Dishwasher?

Published in Dishwasher Repair 4 mins read

To unblock an integrated dishwasher, you can often resolve the issue by clearing common blockage points, including using a simple homemade solution for drain clogs.

Integrated dishwashers can become blocked for various reasons, most commonly due to food debris or other foreign objects obstructing the drainage system. Addressing these blockages typically involves inspecting and cleaning specific components.

One effective method, particularly for clearing the drain, is to use a baking soda and vinegar solution. Since it is common for debris to get stuck in the dishwasher drain, try cleaning it with a solution of equal parts baking soda and vinegar.

Using Baking Soda and Vinegar for Drain Clogs

This natural method can help break down grease and food particles causing a blockage in the drain.

Here's how to use this solution based on the provided reference:

  1. Prepare the Solution: Mix equal parts baking soda and vinegar. For a typical dishwasher, about half a cup of each should suffice.
  2. Apply to Drain: Pour the baking soda and vinegar mixture directly into the bottom of the dishwasher tub, targeting the drain area.
  3. Let it Sit: Allow the solution to sit for at least 15 minutes to work on the blockage.
  4. Run a Cycle: After 15 minutes, close the dishwasher door and run a rinse cycle. It's recommended to run the cycle at the highest heat setting to help flush out the loosened debris.

This method is often sufficient for minor clogs caused by accumulated food particles in the drain.

Other Common Blockage Points

If the baking soda and vinegar method doesn't resolve the issue, the blockage might be elsewhere in the system. It's important to check these areas with the dishwasher's power turned off at the breaker for safety.

  • Drain Filter: Located at the bottom of the dishwasher tub, the filter catches larger food particles. It can become clogged over time.
    • How to check: Remove the filter (consult your manual for specific instructions), rinse it thoroughly under running water, and remove any trapped debris.

  • Drain Hose: The hose connecting the dishwasher to the sink drain or garbage disposal can get kinked or clogged.
    • How to check: Inspect the hose visually for kinks. If accessible, disconnect it (ensure water is shut off) and check for blockages using a long brush or by flushing it with water.
  • Air Gap (if applicable): If your installation includes an air gap on your sink countertop, check if it's clogged.
    • How to check: Remove the air gap cover and cap, and clear any debris blocking the port leading to the drain hose.

Potential Blockage Locations

Understanding where blockages commonly occur helps in troubleshooting.

Component Location Common Cause Resolution Steps
Drain Filter Bottom of dishwasher Food particles, grease Remove, rinse, clean
Drain Bottom of dishwasher Food debris, grease Baking soda & vinegar solution, manual cleaning
Drain Hose Under sink/behind unit Kinks, debris buildup Inspect, straighten, flush or clear manually
Air Gap Sink countertop (if used) Debris accumulation Remove cover, clear blockage

Important: Always disconnect power to your dishwasher before inspecting or cleaning internal components to avoid electrical hazards. If you are uncomfortable checking these parts yourself, or if the blockage persists, it is best to contact a qualified appliance technician.

Clearing clogs regularly, especially cleaning the filter and using preventative measures like scraping plates before loading, can help maintain smooth operation and prevent future unblocking issues.
