Miele Washer Error Code F34/F35

Miele washers are known for their durability and precision engineering, but sometimes error codes like F34 and F35 can disrupt your laundry routine. These error codes signal issues with the door locking and unlocking system. Understanding the causes and solutions of these errors will help you fix the problem quickly and get your washer running smoothly again.

What Do Error Codes F34 and F35 Mean?

Both F34 and F35 indicate problems with the door lock mechanism:

• F34: The washer is having trouble locking the door at the start of a cycle.

• F35: The washer is unable to unlock the door at the end of a cycle.

These errors usually stem from mechanical or electrical issues related to the door lock system.

Common Causes of Miele Washer Error Code F34/F35

• Obstructions in the Door or Lock: Clothing, small objects, or debris caught in the door or locking mechanism can prevent proper operation.

• Faulty Door Lock Switch: The door lock switch may be defective, damaged, or worn out.

• Loose or Damaged Wiring: Connections between the door lock and the control board can become loose or damaged.

• Control Board Malfunction: Rarely, a problem with the control board itself may cause door lock errors.

Step-by-Step Troubleshooting for F34/F35 Errors

1. Inspect and Clear Door Obstructions

Start by thoroughly checking the door seal, latch, and surrounding area. Remove any clothing, small objects, or dirt that might be jamming the lock or latch.

2. Power Cycle the Washer

Unplug the washer from the power outlet and wait for about 5 minutes. Plug it back in and restart the machine. This simple reset can clear temporary glitches causing the error.

3. Examine the Door Lock Mechanism

If the problem persists, visually inspect the door lock switch for physical damage. Look for cracks, broken parts, or wear that could prevent it from engaging or releasing properly.

4. Check and Secure Wiring Connections

Inspect the wiring harness connected to the door lock switch and control board. Make sure all connectors are tight, and wiring shows no signs of damage or corrosion. Repair or replace any faulty wiring.

5. Replace the Door Lock Switch if Needed

If your inspections show a faulty door lock switch, replacement is often the best solution. Refer to your Miele washer manual for part numbers or consult a professional technician for assistance.

When to Call a Professional

If you have followed the troubleshooting steps and the F34 or F35 error codes still appear, it’s advisable to contact a certified Miele service technician. Electrical issues or control board faults require specialized diagnostic tools and expertise to fix safely and effectively.
