Diagnosis
When your dishwasher fails to empty, it typically indicates a clog somewhere in its draining mechanism. This could be within the drain hose, the filter basket, or the air gap. If this problem isn't addressed, stale water will remain pooled at the bottom, rendering the appliance unusable and possibly leading to unpleasant smells.
Tools Needed
- Screwdriver set
- Pliers
- Bucket
- Old towels or rags
- Gloves
- Stiff brush or wire
Warnings
- Always disconnect power to the dishwasher before starting any repairs to avoid electrical shock.
- Be careful when handling sharp objects that might be inside the dishwasher or drain hose.
- Wear gloves to protect your hands from dirty water and sharp debris.
Step-by-Step Instructions
- Begin by cutting off the power to your dishwasher at the circuit breaker for your safety.
- Prepare for water spillage by placing a bucket and towels beneath the dishwasher.
- Find and detach the drain hose, either from the dishwasher unit itself or from where it connects to your sink's drain.
- Carefully examine the end of the drain hose for any bends or obstructions.
- Use pliers or a sturdy wire to gently remove any accumulated debris from inside the drain hose.
- Take out the dishwasher's filter, typically located at the base of the interior tub, and clean it thoroughly.
- If your sink is equipped with an air gap, check it for blockages and clear it out if necessary.
- Reattach the drain hose, ensuring it is securely connected.
- Turn the power back on at the circuit breaker.
- Run a brief rinse cycle to confirm that the water is now draining as it should.
Troubleshooting
- If it still doesn't drain, check the garbage disposal connection point to ensure it's not clogged there.
- Verify that the drain hose isn't routed too high, which can prevent proper drainage.
- Consider calling a professional if you suspect an issue with the pump or internal plumbing.
Preventive Tips
- Scrape food scraps off dishes before loading them into the dishwasher.
- Regularly clean the dishwasher filter (monthly is a good rule).
- Run hot water in the sink before starting the dishwasher to help clear the drain line.
