Victory Freezer Error Code E10: Clock Alarm

What does Victory error code E10 mean?

E10 is the clock alarm in the Victory FS and FSA alarm table. The Eliwell-type controller contains a real-time clock that keeps the time of day so that timed events, such as scheduled defrosts or alarm records, happen when they should. If the clock loses its stored time, which can follow a long power loss, the controller shows E10 to say the time setting is gone. The manual's table gives the meaning as a real-time clock that has lost its time setting. For this code it lists only the LED state, relay behavior, reset type and enabling parameters. It names no cause and gives no operator steps, including how to set the time again. So we can say what E10 reports, but the way to clear it has to come from the controller's own instructions or a technician. The alarm is about timekeeping, not temperature, so it does not by itself mean food is at risk.

Affected models and control systems

E10 is listed for Victory FS and FSA hydrocarbon freezers with an Eliwell-type controller and probes Pb1 to Pb5, in the alarm table on printed pages 18-19. Not every unit uses timed defrost, so the effect of a lost clock depends on how the individual unit is set up.

Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.

What you may notice

• E10 on the controller display
• Alarm LED lit
• Time-based functions such as defrost starting at the wrong time of day

Possible causes

Likely causes — what usually sits behind error code E10 on this control. A technician confirms which one it is before any part is replaced.

• Power to the freezer was off long enough for the clock to lose its time
• Clock backup energy source worn out, so the time is lost at every power-off
• Controller memory error that cleared the stored time

Safe checks before calling for service

How a technician diagnoses error code E10

1. Read the alarm and note the time of the last power event.
2. Set the real-time clock using the controller's documented procedure and confirm it holds.
3. Cycle power briefly and see whether the time is retained.
4. Check the clock-related parameters and any timed defrost schedule.
5. Check the controller and its backup source if the time is lost again after a short outage.

How error code E10 differs from similar codes

E10 concerns the clock only. Probe alarms such as EL and Ei concern temperature inputs, and voltage alarms HiP and LoP concern the supply.
