E3
Whirlpool Washing Machine
Severity: ModerateWhat Does This Error Mean?
The E3 error means the water level sensor in your Whirlpool washer is detecting a problem. The washer thinks the water level is too high, too low, or can't be read. This sensor tells the washer when to stop filling and when to start draining.
Affected Models
- WTW5000DW
- WFW5620HW
- WTW4816FW
- WFW9620HW
- Most Whirlpool top-load and front-load washers
Common Causes
- The pressure switch hose is kinked, clogged, or disconnected
- The water level pressure switch is faulty
- The drain pump is running too slowly, causing water to back up
- A suds lock — too much detergent created excessive foam
- The air dome or pressure chamber is clogged with debris
How to Fix It
-
Check if you used too much detergent in the last wash.
Excessive suds can fool the water level sensor. Use HE (high efficiency) detergent in the correct amount.
-
Run an empty rinse and spin cycle to clear excess suds.
This flushes out the extra detergent and resets the water level.
-
Unplug the washer for 5 minutes, then plug it back in.
A power reset clears temporary sensor glitches.
-
Check the drain hose for proper positioning.
The drain hose should be 4–8 inches into the standpipe. Too deep can create a siphon effect.
-
If the error persists, the water level pressure switch may need replacement.
Contact a technician for proper diagnosis and repair.
When to Call a Professional
If reducing detergent and checking the hose doesn't fix it, the pressure switch may need replacement. A technician can test the switch and check the air dome. Expect repair costs of $100–$225 including parts and labor. The pressure switch itself is usually $20–$50.
Frequently Asked Questions
Can too much detergent cause the E3 error?
Yes, this is actually one of the most common causes. Excessive suds trick the water level sensor into thinking the tub is overfilling. Always use HE detergent in front-load washers. Use the amount recommended on the bottle — usually less than you think.
What is the pressure switch on a washing machine?
It's a sensor that measures the water level inside the tub. It works by detecting air pressure in a small hose connected to the tub. As water rises, pressure increases, and the switch signals the control board. When it fails, the washer can't tell how much water is inside.
Why does my Whirlpool washer keep overfilling?
A faulty water level pressure switch can't tell the washer to stop filling. The inlet valve may also be stuck open. If your washer is overfilling, turn off the water supply immediately. Call a technician — overfilling can cause water damage to your home.
