# How to Fix Bosch Error E35 (Door Lock)
The Bosch Error Code E35 is a critical fault that directly relates to the **Door Lock Circuit** or the **Door Lock Assembly** itself. When this error appears, the washer believes the door is not locking correctly (or not unlocking correctly), and it will immediately stop the cycle to prevent flooding or injury.
This is a protective measure, and in most cases, it indicates a failure of the mechanical component that secures the door.

## 1. Explanation: What E35 Means in Plain English
| Code | Component Affected | Meaning |
| :— | :— | :— |
| **E35** | Door Lock / Door Latch | The main control board (PCB) is not receiving the correct feedback signal from the door lock assembly. The lock either failed to engage after the cycle started or failed to release after the cycle ended. |
**The Likely Culprit:** The most common cause for E35 is an electrical or mechanical failure within the **Door Lock Assembly** (also known as the Door Interlock or Latch).

## 2. Step-by-Step Fix: How to Diagnose the E35 Error
Before assuming the lock needs replacement, perform these crucial troubleshooting steps, starting with the simplest checks.
### Step 1: Perform a Hard Reset
Electrical glitches can sometimes trigger false error codes.
1. **Unplug:** Completely disconnect the washing machine from the power outlet. Do not simply switch it off at the wall—pull the plug.
2. **Wait:** Leave the machine unplugged for a minimum of **5 minutes**. This allows the main control board to fully discharge and reset its memory.
3. **Plug Back In:** Restore power and attempt to run a short test cycle (like a Drain/Spin cycle). If the error immediately reappears, proceed to Step 2.
### Step 2: Check for Physical Obstructions
If the door cannot physically close properly, the lock assembly cannot engage the striker, and the E35 error will occur.
1. **Check the Gasket:** Open the door and carefully inspect the rubber door gasket (bellows). Ensure no small socks, items of clothing, or debris are trapped that could prevent the door from fully seating.
2. **Inspect the Door Striker:** Examine the metal tongue or striker piece attached to the door itself. Ensure it is straight, undamaged, and securely attached to the door. If it is bent, it won’t align with the lock assembly housing.
3. **Attempt to Re-Latch:** Firmly close the door, ensuring you hear a distinct “click.” Do not slam it, but apply pressure to confirm it is fully seated.
### Step 3: Check Drainage (If Water is Present)
If the machine still has water inside, many Bosch models will prevent the door from unlocking (or signaling readiness to lock) as a safety precaution.
1. **Drain the Machine:** Use the machine’s drain function or perform a manual drain via the filter access panel at the bottom front of the machine.
2. **Confirm Empty:** Once the machine is completely empty, try the test cycle again.
### Step 4: Component Inspection (The Final Diagnosis)
If the error persists after confirming the machine is clear, dry, and reset, the door lock assembly itself is likely faulty. You need to visually inspect the component.
**⚠️ Safety First:** Always unplug the machine before attempting physical inspection or repairs.
1. **Access the Lock:** The lock assembly is located inside the front panel frame, right behind the door latch area. You may need to partially pull back the rubber door seal (gasket) to view the component.
2. **Check Wiring:** Look for obvious signs of damage to the two or three wires leading into the lock assembly. Wires that are cut, frayed, or appear melted must be addressed.
3. **Look for Burning:** Inspect the lock assembly housing for signs of heat damage, black scorch marks, or a plastic burning smell. If any of these are present, the internal solenoid or thermal switch inside the lock assembly has failed.
**Conclusion:** If the wiring is intact and there are no obstructions, the internal electromechanical components of the Door Lock Assembly have failed and require replacement.

## 3. Component Replacement
The Door Lock Assembly is a common replacement part and is typically straightforward to install, requiring only a screwdriver and the ability to maneuver the rubber gasket.
