E41
Bosch Washing Machine
Severity: ModerateWhat Does This Error Mean?
The E41 error on your Bosch washer means the door is not locked at the start of a cycle. The washer detected that the door latch did not fully engage when the cycle was supposed to begin. It will refuse to run until the door is properly secured.
Affected Models
- Bosch 300 Series
- Bosch 500 Series
- Bosch 800 Series
- Bosch WAT Series
- Most Bosch front-load washers
Common Causes
- The door was not pushed shut firmly enough before starting the cycle
- The door latch hook is bent, worn, or broken and won't catch
- Laundry or a foreign object is caught in the door opening
- The door strike on the machine body is damaged or misaligned
- An electrical fault in the door lock module is preventing it from engaging
How to Fix It
-
Open the door completely, check for any clothing items caught in the seal or latch area, then close it firmly.
A single sock wedged near the latch is enough to trigger E41.
-
Close the door with a firm push until you hear a clear click, then try starting the cycle.
Front-load washers require a positive latch engagement — a gentle close is not always enough.
-
Unplug the washer from the wall socket for two minutes, then plug it back in and retry.
A power reset clears temporary control board errors that can trigger a false E41.
-
Inspect the door latch hook and the strike plate on the machine body for visible damage or misalignment.
If the hook looks bent or the strike plate has shifted, these can sometimes be bent back carefully or re-seated.
-
If none of the above work, the door lock module (also called the door interlock) needs to be replaced.
This part typically costs $30–$90. A qualified technician can replace it in about an hour.
When to Call a Professional
If the door closes and clicks but E41 keeps appearing, the door lock module likely has an internal fault. A technician can test the lock with a multimeter and replace it if needed. Expect repair costs of $120–$270 including parts and labor.
Frequently Asked Questions
Is the E41 error dangerous to ignore?
You cannot ignore it — the washer simply will not start a wash cycle with E41 active. It is a safety interlock designed to prevent the door from opening while the drum spins. Fix the door latch before using the machine.
What is the difference between Bosch error E01 and E41?
Both relate to the door lock. E01 usually means the lock failed during or after a cycle. E41 specifically means the door failed to lock at the very start of a new cycle. The fix steps are similar for both.
How long does it take to replace a Bosch door lock module?
A technician can usually replace the door lock module in 45 minutes to an hour. It involves removing the door seal and a few screws to access the lock. The part itself costs roughly $30–$90.
