Error codeF1 / F-1
ApplianceWall Oven
Quick answer
F1 is the ERC system watchdog alarm: the oven beeps until cancel or another function is selected.
Model compatibility: Dacor reuses codes across series and model years, so F1 / F-1 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
Alarm, system watchdog circuit: ERC detects a failure in the internal watchdog element-relay circuits; beeps until cancel.
F1 on a Dacor oven with ERC control is the System Watchdog Circuit alarm. The control has detected a failure in the internal watchdog element relay circuits and starts a cancel feature.
What you see and hear
F1 appears in the time digits and the oven beeps until you press cancel or choose another function. It can be detected in cook mode or time of day mode.
What it means
The ERC is picking up a command to supply heat without getting an input from the membrane. The watchdog circuit is designed to prevent that.
What to do
Press cancel. If the beep goes on after that, the manual says to check the main control (ERC), which is a technician job, so call service.
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.
