Whirlpool Dishwasher: Not Draining
Understanding the Problem
Standing water after the cycle points to a clogged drain hose, faulty drain pump, or blocked garbage disposal connection.
Below, we walk through the most common causes for a Whirlpool dishwasher that is not draining, list the specific OEM parts you may need, and show you how to verify compatibility with your model number.
Step-by-Step Diagnosis
- Identify the symptom clearly. When exactly does the problem occur? During which cycle or under what conditions? Note any error codes on the display.
- Check the simple things first. Verify power supply, check circuit breakers, inspect for obvious blockages or damage. Many issues have a simple fix.
- Locate your model number. Find the model/serial number plate (usually on the door frame, back panel, or inside the door). You'll need this to order the correct parts.
- Test the suspected component. Use a multimeter to check continuity on electrical parts. Visually inspect mechanical parts for wear, cracks, or damage.
- Order the right OEM part. Use our Parts Finder or search your model number to see every compatible part for your specific unit.

When to Call a Professional
While many dishwasher repairs are DIY-friendly, consider calling a certified technician if:
- The repair involves gas lines, refrigerant, or high-voltage components
- You're unsure about the root cause after diagnosis
- The appliance is still under warranty (DIY repair may void coverage)
- Multiple components appear damaged simultaneously
Frequently Asked Questions
How do I find my Whirlpool dishwasher model number?
The model number plate is typically located on the door frame, inside the door, on the back panel, or behind the kick plate. It usually starts with letters followed by numbers.
Are OEM parts worth the extra cost vs aftermarket?
OEM (Original Equipment Manufacturer) parts are engineered specifically for your appliance model. They typically fit perfectly, meet safety certifications, and don't void your warranty. For critical components, OEM is strongly recommended.
How long does it take to fix a dishwasher that is not draining?
Most single-part replacements take 30-60 minutes for a confident DIYer. Diagnosis may add 15-30 minutes. More complex issues involving sealed systems or electronics may take longer.
