Error codeF + number
ApplianceWall Oven
Quick answer
An F plus a number on a DCS wall oven is a technical fault; note the code and call service once the oven has cooled.
Model compatibility: DCS reuses codes across series and model years, so F + number 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
Technical fault shown as the letter F followed by a number.
Technical fault is the meaning of an F code on a DCS wall oven, shown as the letter F and a number. The manuals leave each number undefined, so the main use of the code is to give it to service.
Models covered
The older WODV230 and WOSV230 guide, and the WOSU30, WOSV30, WODU30 and WODV30 guide, where the number is shown in the clock display.
Sequence
Write the code down.
For the WOSU30 group: temperature knob and oven mode knob to OFF, then PUSH TO CLEAR.
Keep mains power connected while the fans run. When the oven is cool, call Customer Care or a service center with 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.
