If your Whirlpool washer stops during a cycle and shows a code on the display, that code is usually meant to point you toward the problem area. Some Whirlpool Washer Error Codes are related to drainage, some are tied to water supply or door locking, and others involve oversudsing, load detection, or control issues.
This guide brings the most common Whirlpool washer error codes together in one place so you can understand what each one usually means and what to check first. If you want broader brand navigation, you can also return to the Washer Code Guide homepage.
Most Common Whirlpool Washer Error Codes
Here are some of the most common Whirlpool washer error codes users run into:
- F21 – Long drain problem
- F9 E1 – Drain issue or long drain condition
- LF – Long fill problem
- SUD – Oversudsing detected
- LOC – Control lock enabled
- F5 E2 – Door lock issue
- F7 E1 – Basket speed or motor-related issue
- DRN – Drain problem
The exact meaning can vary slightly by model, but the code usually still points to the same general area of the problem.
Whirlpool Washer F21 Code
The F21 code usually means the washer is taking too long to drain. In many cases, the cause is a clogged drain filter, restricted hose, weak drain pump, or a blockage in the household drain system.
Common causes of Whirlpool F21 code
- Blocked drain filter
- Kinked drain hose
- Drain pump issue
- Slow home drain line
If you want the full guide for this specific fault, see the Whirlpool Washer F21 Code page.
Whirlpool Washer F9 E1 Code
The F9 E1 code also points to a drain problem. The washer believes water is not leaving the tub within the expected time, so the cycle stops before it can finish normally.
Common causes of Whirlpool F9 E1 code
- Restricted drain hose
- Clogged pump or filter area
- Drain pump trouble
- Improper drain setup
This fault is closely related to the Whirlpool Washer F21 Code, since both usually involve slow drainage.
Whirlpool Washer LF Code
The LF code usually means long fill. The washer is not getting enough water within the expected time.
Common causes of Whirlpool LF code
- Water valves not fully open
- Inlet hose restriction
- Dirty inlet screens
- Low water pressure
Start by checking the water supply valves, inlet hoses, and inlet screens.
Whirlpool Washer SUD Code
The SUD code usually means the washer has detected too many suds. This often happens when too much detergent is used or the wrong type of detergent is added.
Common causes of Whirlpool SUD code
- Too much detergent
- Wrong detergent type
- Drain system restriction causing suds-related delay
In some cases, oversudsing and poor drainage can appear together.
Whirlpool Washer LOC Code
The LOC code usually means the control lock feature is on. In many cases, this is not a real washer fault and the machine is simply locked from button input.
Common causes of Whirlpool LOC code
- Control lock turned on
- Buttons pressed accidentally
- Lock setting carried over from the last cycle
Whirlpool Washer F5 E2 Code
The F5 E2 code usually points to a door lock problem. The washer may think the door is not latched correctly or cannot confirm safe locking.
- Door not fully closed
- Latch obstruction
- Door lock assembly issue
Whirlpool Washer F7 E1 Code
The F7 E1 code is commonly related to basket speed, motor response, or drum movement problems on some models.
- Motor or drive issue
- Basket speed sensing issue
- Overload or resistance problem
Whirlpool Washer DRN Code
The DRN code is another drain-related message. It usually means the washer is not draining the way it should.
- Drain restriction
- Pump trouble
- Hose blockage
How to Reset a Whirlpool Washer
Sometimes a Whirlpool washer error code is caused by a temporary control interruption. A simple reset is often worth trying before assuming the washer needs repair.
- Turn the washer off
- Unplug it from power
- Wait about 5 minutes
- Plug it back in
- Restart a short cycle
A reset can clear temporary glitches, but it will not permanently fix a blocked hose, failed pump, latch problem, or sensor issue.
When a Whirlpool Washer Error Code Needs Service
Some Whirlpool washer codes are tied to user-correctable problems such as closed water valves, too much detergent, a control lock setting, or a clogged drain path. Others may involve the pump, door lock system, motor, or internal controls.
You may need service if:
- The same code keeps returning after troubleshooting
- The washer will not drain, fill, spin, or lock correctly
- You hear unusual pump or motor noises
- The machine stops at the same stage every cycle
- A reset does not help at all

Final Thoughts
Whirlpool Washer Error Codes help narrow down the problem area, even if they do not always identify the exact failed part immediately. Codes like F21, F9 E1, and DRN often point to drainage trouble, while LF, SUD, and LOC are commonly tied to water supply, detergent, or control settings.
Start with the basics first: check the water supply, drain path, detergent use, door closure, and a full reset. If the same Whirlpool washer error code keeps coming back, the machine may need closer diagnosis or professional repair.
