Solutions:
- Check the harness connection.
- Check if the drum is rotating with your hands; if not, replace the drum rollers.
- Check the rear bearing group and replace it if necessary.
- Check the motor resistance.
- Check the main PCB.
E08: Voltage frequency error.
Solutions:

- replace the main PCB.
Winia Dryer Auto-Test Mode
Service AUTOTEST allows technicians to test all dryer cycles in a few minutes and discover the error codes.
How to Place the Dryer into Service: AUTO-TEST
Step 1
- Enter the service AUTOTEST:
- Press and hold the “Drying Level” button.
- Put the selector knob in the third program (“Iron Dry” => Cotton program section).
- Turn the selector knob to the first program (“Extra Dry” => cotton program section), and after 3 seconds, the script “SAU” will be displayed.
- Press the Start/Pause button, and the appliance will enter the service AUTOTEST.
Step 2
- When the selector knob is positioned in the second program (“Cupboard Dry” => Cotton program section), the AUTOTETST steps start.
| knob position: | Control: |
|---|---|
| Second program | Aqua-switch testing |
| Third program | pump testing. |
| Fourth program | The motor rotates counterclockwise. |
| Fifth program | The motor rotates clockwise. |
| Sixth program | heater testing. The display shows 255. |
| Seventh program | Door NTC testing The display shows 255. |
| Eighth program | cooling fan testing. |
| Ninth program | Compressor testing |
| Tenth program | conductivity sensor testing. |
How to exit the service AUTOTEST:
- Method 1: set the selector knob to the OFF position.
- Method 2: Unplug the dryer.
Multimeter and component tester
Motor Testing:
Component Tester:
- Check whether the motor cable is connected properly.
