What Does Error Code E02 Mean on a Bosch Washing Machine?

Door lock failure — cannot lock door for cycle.

E02 fires when the control board fails to receive confirmation that the door interlock has engaged within its expected window at cycle start. The board energizes the lock solenoid, then checks the lock switch feedback; if the latch cannot close fully or the switch never confirms, the code triggers and the wash is blocked. This differs from door-open faults or drain-related codes like E04—E02 specifically points to the locking mechanism, latch alignment, or solenoid, not water flow.

Models affected: Bosch front-load washers, including models such as WAT28400UC and WGA12400UC
What owners report: Owners commonly report E02 appearing right at the start of a cycle, often after overloading, when a sleeve or towel edge is pinched in the gasket. A frequent quick win is reopening the door, clearing any trapped laundry, and firmly pressing it shut until it clicks; if it still won't lock after a clean latch, a worn latch or solenoid is the more likely culprit.

Frequently Asked Questions

Can I keep using my Bosch Washing Machine when error E02 appears? +
You often can for a cycle or two, but the door issue behind E02 will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes E02 on a Bosch Washing Machine? +
Across reported Bosch washing machine repairs, the most frequent is door latch worn or broken (40% of cases), laundry caught in door seal (35%), then door lock solenoid failure (20%). Check them in that order before replacing any parts.
E02 keeps coming back after a reset — what should I check next? +
A reset only clears the stored E02 fault; if it returns, the door problem is still present. Move on to the physical checks — check door seal for caught items, then inspect door latch — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix Bosch Washing Machine error E02? +
A DIY repair typically runs $35–$80 in parts, versus $150–$320 for a professional service call, so handling it yourself saves around $115. Expect the work to take roughly 30–60 minutes.
Which Bosch Washing Machine models show error E02? +
E02 is documented on Bosch front-load washers, including models such as WAT28400UC and WGA12400UC. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
