What PE (Dishwasher Water Level Sensor) Means
PE indicates an issue with the water level sensor, which LG's dishwasher Help Library article notes is applicable to certain older models - the dishwasher uses this sensor to help prevent leaks by detecting water level.
Common Causes of PE (Dishwasher Water Level Sensor)
- Water level sensor has failed (older model platforms)
🔧 One Safe Check You Can Try
There's no owner-level fix LG documents for PE - request service for inspection of the water level sensor.
⚠ Why You Shouldn't Go Further Than That
- LG's article goes directly to requesting service for this code without an interim troubleshooting step, since it's tied to leak-prevention safety logic that shouldn't be worked around.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
