tE
LG tE on a dishwasher: temperature sensor problem
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
On an LG dishwasher, tE points to a temperature sensor problem, such as a poor contact or a sensor failure. LG gives no home steps for tE: it asks for a service inspection. Note the code and the model.
Safety first
Stop and check this first
- The temperature sensor sits in the base next to the heating circuit and mains voltage: checking it is for the service technician, not the owner.
Safe checks you can perform
- Code, model and date
- When tE appears
- Using the unit until the inspection
Leave these tasks to a qualified professional
- Do not attempt this professional task: Sensor and connection measurement
- Do not attempt this professional task: Test cycle with heating
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Sensor and connection measurement
What they doWith the unit disconnected, the technician checks the temperature sensor connector and wiring and measures its resistance against LG specification.
They must show youthe measured value against specification and the connector condition.
In writingwhat was measured, the result and, if the sensor is replaced, its reference and the reason.
Test cycle with heating
What they doAfter the repair, the technician runs a programme that heats the water and checks it finishes without tE.
They must show youa heated cycle completed with no code.
In writingthe test, the result and the date.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Code, model and date
- Who:
- you.
- How:
- photograph the panel showing tE and the model and serial label; the manual says where it is.
- Result that matters:
- the service knows which sensor your unit has before the visit.
- If the unit is under warranty:
- say so when you request service.
- If you cannot find the label:
- the manual says where it is.
- Evidence to keep:
- the dated photos.

When tE appears
- Who:
- you, by watching.
- How:
- note whether tE shows right at the start or when the cycle should heat the water, and whether it happens on every programme.
- Result that matters:
- a useful fact to separate an intermittent contact from a sensor that does not read.
- If it always shows at the start:
- tell the technician.
- If it comes and goes or only on some programmes:
- write down which; it points to an intermittent contact the technician should check.
- Evidence to keep:
- a note with programme, stage and date of each occurrence.

Using the unit until the inspection
- Who:
- you.
- How:
- do not take the unit apart to look for the sensor; stop repeating cycles with tE and wait for the inspection LG asks for.
- Result that matters:
- not complicating the diagnosis or handling mains powered parts.
- If the code clears by itself:
- still tell the technician, an intermittent contact can return.
- If it persists:
- keep the service appointment.
- Evidence to keep:
- note whether it cleared and when.

What it means
According to the LG guide, tE covers temperature sensor problems on the dishwasher: a poor contact at its connection or a failure of the sensor itself. The control uses that reading to manage water heating, so with tE it cannot watch the wash temperature properly. LG says tE requires a service inspection. The code does not separate connector, wiring and sensor: only measuring the sensor resistance and checking its connections does that.

Symptoms and causes
Probable causes · in order
- Poor contact at the sensor connectionPossible
LG names it explicitly. It stands apart from a failed sensor when the technician checks the connector and the reading is correct again after remaking the contact.
Evidence: [LG Dishwasher] Guide to Error Codes
- Failed temperature sensorPossible
The other cause LG lists. Only measuring the sensor against the maker's specification confirms it; the code alone is not enough to replace it.
