LC
Whirlpool Refrigerator
Severity:What Does This Error Mean?
The LC error on a Whirlpool refrigerator typically indicates a problem with the water dispenser line or a leak detection event. On some models, LC can also indicate a communication fault between the dispenser control and the main board. The water dispenser may stop working when this error is active.
Affected Models
- WRS325SDHZ
- WRF535SWHZ
- WRS571CIHZ
- WRF767SDEM
- Whirlpool models with external water and ice dispensers
Common Causes
- The water dispenser line has a leak or loose connection inside the door
- The water filter is clogged or installed incorrectly, causing a pressure fault
- The water inlet valve is leaking and a moisture sensor has detected water
- A communication error has occurred between the dispenser board and the main control board
- The dispenser door flap is stuck open, triggering a system fault
How to Fix It
-
Unplug the refrigerator for 5 minutes to perform a full reset.
Many LC errors caused by temporary communication glitches clear with a power reset.
-
Check the water filter — make sure it is properly seated.
Twist the filter until it clicks firmly into place. A loose filter causes pressure issues that can trigger dispenser errors.
-
Replace the water filter if it's older than 6 months.
A clogged filter restricts water flow significantly. Whirlpool recommends replacing filters every 6 months or at 200 gallons.
-
Inspect the floor under and around the refrigerator for any water.
If you see water on the floor, there is a real leak — likely from the water inlet valve or a loose supply line. Do not ignore this.
-
Check the dispenser recess in the door for moisture or ice buildup.
Ice can form in the dispenser chute and cause the flap to stay open. Clear any ice with warm water.
When to Call a Professional
If resetting and replacing the water filter doesn't clear the LC error, a technician should inspect the water inlet valve and dispenser line connections. A leaking water valve can cause water damage inside the refrigerator and to your floor. Repair costs range from $100–$250 depending on the component.
Frequently Asked Questions
How do I know if the LC error means a real leak or just a sensor fault?
Check the floor around and behind the fridge for standing water. Also open the refrigerator and look inside the bottom for pooled water. If you find water anywhere, there is a real leak. If everything looks dry, the error is likely a sensor glitch or dispenser pressure issue.
Will the water dispenser work while the LC error is showing?
On most Whirlpool models, the water dispenser is disabled when LC is active. This is a precaution to prevent further water flow if there is a leak. Resolve the error first, then test the dispenser.
How often should I replace the water filter in my Whirlpool refrigerator?
Whirlpool recommends replacing the water filter every 6 months or after 200 gallons of use — whichever comes first. A clogged filter not only affects water quality but can also cause dispenser pressure errors like LC. Most Whirlpool models have a filter change indicator light that turns red when it's time.
