Step-by-Step Guide:

1. Turn Off the Power

For safety, unplug the dishwasher or turn off its circuit breaker.

2. Remove Standing Water

Use a cup or towel to remove excess water from the bottom of the dishwasher.

3. Check the Dishwasher Filter

• Locate the filter at the bottom of the dishwasher (usually beneath the spray arms).
• Twist or lift it out and clean it under warm water.
• Use a toothbrush to remove any debris.

4. Inspect the Drain Hose

• The drain hose is usually under the sink, connected to the garbage disposal or sink drain.
• Detach it using pliers and check for clogs.
• Run water through it or use a wire hanger to clear obstructions.

5. Check the Garbage Disposal (If Applicable)

• If your dishwasher drains through a garbage disposal, make sure it's not clogged.
• Run the disposal to clear any blockages.
• Also, check if the drain plug (inside the disposal where the hose connects) was removed during installation.

6. Use Baking Soda & Vinegar

• Pour 1 cup of baking soda and 1 cup of vinegar into the dishwasher drain.
• Let it sit for 15-30 minutes, then flush with hot water.

7. Plunge the Drain (If Necessary)

• Use a small plunger over the drain inside the dishwasher to dislodge any blockages.

8. Run a Test Cycle

• Reconnect everything and restore power.
• Run a short cycle to check if the water drains properly.

If the clog persists, there might be a deeper plumbing issue that requires a professional plumber.
