Troubleshooting

E 04 - Outlet air - Sensor has short-circuited 

Error description

This error code indicates that the outlet air thermistor, connected to the PCB, or the 
harness from the board to the thermistor, has short circuited.  
A defective PCB can also cause this error.
The dryer stops operating.

Error analysis

2. Defective 
NTC interface 
on PCB?

Measure the resistance 
of the NTC sensor and 
harness between P18-5 
and P18-6 on main circuit 
board.
Is the resistance between 
4 to 6 k

Ω

 at 20°C (68°F)?

Replace NTC sensor 
or harness.

Go to step 2.

NO

YES

YES

Replace the PCB.

1. Defective 
NTC sensor or 
harness?

Alternative

Measure the voltage between GND and T1
