E23
Bosch Dryer
Severity: ModerateWhat Does This Error Mean?
E23 means the Bosch dryer door latch or door switch has reported a fault during a cycle. The dryer monitors the door during operation — if the switch detects the door has opened or if the switch itself fails, E23 is triggered and the dryer stops. This is a safety feature to prevent hot air escaping and laundry from spilling out.
Affected Models
- Bosch WTW87565GB
- Bosch WTH84000GB
- Bosch WTV74100GB
- Bosch WTB86200GB

Common Causes
- Door latch worn or broken — the door hook no longer holds the door firmly closed
- Door strike (receiver) worn — the latch engages but the switch is not activated
- Door switch wiring loose or broken — switch works physically but signal is interrupted
- Door hinge worn — door has dropped slightly and the latch no longer aligns with the strike
- Foreign object preventing the door from fully closing — laundry or lint caught in the door seal
How to Fix It
-
Open the door and firmly close it — push until you hear a clear click.
If laundry is close to the door opening, it may be preventing a full close. Rearrange the load and try again.
-
Check the door seal for trapped laundry or lint.
Run your finger around the full circumference of the door seal. A sock, small garment, or compacted lint can prevent the door from sealing completely.
-
Inspect the door latch hook and the receiver on the dryer body.
The hook should be straight and unbroken. The receiver slot should be clear of debris. A worn or broken hook is visible — it may be cracked or no longer spring-loaded.
-
Check whether the door has dropped — look at the alignment of the door edge with the dryer body.
A gap that is larger at the bottom than the top indicates hinge wear. The door is no longer aligned correctly.
-
If the latch is worn, replace the door latch assembly.
Bosch door latch assemblies are available from appliance parts suppliers. Use the model number on the dryer's rating plate to find the correct part.
When to Call a Professional
Door latch replacement is accessible for confident DIYers on many Bosch dryer models. If the door hinge has worn and the door has dropped, a technician visit is recommended. Contact Bosch service on 0344 892 8979 (UK) or via bosch-home.com.
Frequently Asked Questions
Can I run the dryer with E23 by holding the door closed?
No — the dryer needs the door switch to confirm the door is properly latched before it will run. Holding the door closed from outside will not trigger the door switch. Fix the latch before attempting to run the dryer.
