Quick Answer#

Hisense [dishwasher not draining](/blog/dishwasher-not-draining) is most commonly caused by a clogged drain filter/food trap, failed drain pump, or blocked drain hose connection at the garbage disposal or air gap. Check the drain filter first — Hisense dishwashers have a removable filter at the bottom that catches food debris. Estimated repair cost varies by model and condition.

Affected Hisense Models#

This issue is commonly reported on these Hisense dishwasher models:

• Hisense HUI6220XCUS
• Hisense HUI6230XCUS
• Hisense HUI6220XBUS

What Are the Common Causes?#

1. Clogged Drain Filter / Food Trap (35% of cases)#

The drain filter at the bottom of the Hisense dishwasher catches food particles to prevent pump clogs. If not cleaned regularly, it blocks water from reaching the drain pump. Remove the bottom rack, twist out the filter assembly, and clean under running water. Clean monthly — this prevents most drainage issues.

2. Failed Drain Pump (25% of cases)#

The drain pump pushes water through the drain hose. When the impeller breaks or the motor fails, water remains in the bottom. On Hisense dishwashers, the pump is under the filter assembly at the bottom. A buzzing sound during drain without water movement indicates a failed pump. Glass or hard food debris can damage the impeller.

3. Blocked Drain Hose / Garbage Disposal Connection (20% of cases)#

The drain hose connects the dishwasher to the garbage disposal or sink drain. A new garbage disposal installation with an unremoved knockout plug is a common cause. Also check for kinks in the drain hose under the sink. If connected to a disposal, run the disposal before the dishwasher to clear the drain path.

4. Check Valve Stuck Closed (10% of cases)#

The check valve prevents backflow from the drain into the dishwasher. If it sticks closed, water can't drain out. Located in the drain path, usually near the pump. Debris or mineral buildup causes the valve to stick. Cleaning or replacing the valve resolves the issue.

5. Air Gap Clogged (If Installed) (10% of cases)#

If your Hisense dishwasher drain routes through an air gap (the chrome cylinder on the sink), debris inside the air gap blocks drainage. Remove the air gap cap and clean with a bottle brush. Water backing up into the sink during drain cycle confirms an air gap or disposal clog.

Step-by-Step Troubleshooting#

Before starting any troubleshooting on your Hisense dishwasher, disconnect power at the circuit breaker or unplug the unit. For gas appliances, turn off the gas supply valve.

2. Check for error codes: If your Hisense dishwasher has a digital display, note any error codes shown. These narrow the diagnosis to a specific component.
3. Inspect the most likely cause: Based on the causes above, start with the highest-probability component.
4. Test basic components: Check power supply, inspect accessible parts for visible damage, and verify settings are correct.
5. Test operation: After addressing any obvious issues, restore power and run a test cycle. Monitor for 10-15 minutes to see if the symptom recurs.
