What tE (Dishwasher Temperature Sensor) Means
tE means there's an issue related to the temperature sensor, such as a contact problem or an outright sensor failure, per LG's dishwasher Help Library article, which states this requires inspection by a service technician.
Common Causes of tE (Dishwasher Temperature Sensor)
- Temperature sensor contact problem
- Temperature sensor failure
🔧 One Safe Check You Can Try
There's no owner-level troubleshooting step LG documents for tE beyond requesting service - it's a sensor-hardware fault, not something a reset reliably clears.
⚠ Why You Shouldn't Go Further Than That
- LG's own guidance goes straight to "please request service" for this code, without an interim step, because diagnosing a contact issue versus an outright sensor failure needs a technician's tools.
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.
