Error Code tE
Thermal Error — thermistor resistance output abnormal
Moderate
Address soon - your appliance may not work properly
What This Means
Wiring connection from thermistor to main PCB (connector RD6 to WH4) disconnected; Thermistor faulty (resistance should be 8-44 kΩ)
How to Fix
- 1
Check connector RD6 to WH4 connection; replace thermistor if disconnected and problem persists
- 2
Check thermistor resistance: should be 8-44 kΩ; replace thermistor if out of range
- 3
Check voltage between RD6 pin3 and NA8 pin3: should be 1-3V DC; replace main PCB if out of range
