Zojirushi Clock / Memory Retention Issue

Timer or clock loses time or resets unexpectedly between uses.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Unstable power supply, Internal backup capacitor failure, Control board memory fault

Safety first: Ensure a stable power connection.

Avoid unplugging frequently: Leave the cooker plugged in if safe to do so, so the clock remains powered.
Use surge protection: A quality surge protector can help stabilize power.
Reset clock: Follow the manual to set the clock and observe if it drifts significantly.

When to call a technician: Significant time loss or resets without power interruptions indicate internal board issues.
