Error codeA1
ApplianceWall Oven
Quick answer
A1 on a DCS WODV230 / WOSV230 wall oven means the oven has overheated and suspended its functions.
Model compatibility: DCS reuses codes across series and model years, so A1 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
The oven has overheated; it suspends functions and beeps five times.
If your DCS WODV230 or WOSV230 wall oven shows A1, the oven has overheated. It suspends all oven functions and beeps five times.
What to do
Let the oven cool down. Once it has cooled and the door has unlocked, the alert disappears and you can use the oven again. Do not switch off the wall power while the oven is hot, because the cooling fans need it. If the beeping continues, press any button to stop it, and make a note of the code.
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.
