Error Code tE

Heating Error — thermistor out of order

What This Means

Heater connector broken or loose; Heater resistance out of range (should be 12-18 Ω for both wash heater and steam generator heater); Thermistor connector broken or loose; Thermistor resistance out of range (should be approximately 39.5 kΩ at 30°C / 86°F); Water leaked into thermistor connector

How to Fix

1. 1

   Check heater connector (steam generator heater and wash heater) for broken or loose connection — reconnect or repair

2. 2

   Measure heater resistance (pin 1 to pin 2): should be 12-18 Ω; if out of range, replace heater assembly

3. 3

   Check thermistor connector for broken or loose connection — reconnect or repair

4. 4

   Measure thermistor resistance (pin 1 to pin 2 per 9-7 table): at 30°C should be ~39.5 kΩ (±5%); if out of range, replace thermistor assembly

5. 5

   Check for water leakage into thermistor connector — if found, replace thermistor assembly

6. 6

   Note: Control board failure is rare; thermistor circuit sensing parts are only resistors and capacitors
