LG dishwasher codes appear on the control display or as a lock icon on some models. Before a homeowner check, unplug the dishwasher or switch off its circuit, then restore power only after the safe check is complete; CL can usually be cleared by holding the Control Lock button pair, often Half Load and Energy Saver, for at least three seconds, and OE standing water can be force drained by holding Start for at least three seconds. CL, PF, Cd, and St are status messages on supported models rather than parts faults.
The company will ask for it first. It's on a sticker or metal plate, usually in one of these spots:
- Open the door: on the left or right edge of the tub or door
- Some models: on the top edge of the door
LG dishwasher error codes
LG says codes differ by model; PE is for certain older models, and F31, F35, and F37 apply only to models with Dynamic Heat Dry or Auto Open Door.

How do I reset an LG dishwasher error code?
Unplug the dishwasher or switch off its circuit, then restore power after the safe first check is done. If the code returns during the next cycle, write down the exact code and contact a repair company.
What if an LG dishwasher code keeps coming back?
A returning code usually means the control still detects the condition, such as poor draining, a leak, too much suds, or an internal part fault. Stop using the dishwasher if water is leaking or the machine keeps draining, and have a technician diagnose it.
Why do older LG dishwasher manuals show different codes?
Codes vary by model and display style. Some older manuals list E1 for a leak and PE for a water level sensor issue, while newer feature sets add codes such as F31, F35, and F37.
Are CL, PF, Cd, and St LG dishwasher errors?
CL is Control Lock and PF means power was interrupted, so they are status messages rather than parts faults. On models with those features, Cd can mean a drying or storage fan function and St can mean UV sterilization.
