Hisense Dishwasher: not draining

Professional Repair Guide

What is this symptom?

If your Hisense dishwasher is not draining, you're likely facing water pooling at the bottom of the tub after a cycle. This issue can be caused by a clogged filter, a kinked drain hose, or a faulty drain pump. Addressing these common problems can restore your dishwasher's functionality and keep your kitchen running smoothly.

Urgency: Medium

Important Tips for Hisense Models

  • Hisense dishwashers display error codes like E2 for drain timeout or failure; persistent E2 suggests drain pump or control board issue.

Possible Causes

Clogged or blocked filter

How to Identify: Standing water after cycle; debris/food visible in the bottom filter area; improved drainage after filter cleaning in some cases

Part: Dishwasher filter (coarse and fine filter assembly)

Part: Drain hose

Faulty or blocked drain pump

How to Identify: Pump hums with no drainage; debris visible near pump impeller; cleaning doesn’t resolve issue

Part: Drain pump assembly

Sink or garbage disposal blockage

How to Identify: Dishwasher water backs up into sink; garbage disposal slow/drained clogs also affecting dishwasher drainage

Part: Kitchen sink/garbage disposal drain

Air gap/drain connection issue (incorrect or clogged)

How to Identify: Drain water doesn’t exit if air gap blocked or hose not looped properly; visible debris at air gap

Part: Air gap or high loop connection
