Error codeA3
ApplianceWall Oven
Quick answer
A3 on a DCS WODV230 / WOSV230 wall oven is a door lock error after a Self Clean cycle has finished.
Model compatibility: DCS reuses codes across series and model years, so A3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Door lock error: the door cannot be unlocked after a Self Clean cycle has finished.
Self Clean has finished on your DCS WODV230 or WOSV230 wall oven, but the door will not unlock and A3 appears.
What to try
First, turn the power to the oven off at the wall and on again. Next, press on the oven door to help the lock disengage. If the alert comes back, call Customer Care or a service technician.
Call (310) 616-5236 when A3 returns on a DCS wall oven in Los Angeles. Details of wall oven repair are here. Have the model ready and mention that pressing on the door did not help.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
