Zojirushi Extended Cooking Time / Slow Heating

Cooking takes much longer than usual; timer counts down slowly or extends automatically.

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

Low mains voltage, Partially failing heater, Incorrect temperature feedback from sensor, Excessive food quantity beyond rated capacity

Safety first: Ensure stable power supply.

Check load size: Do not exceed the maximum capacity markings inside the inner pan.
Use dedicated outlet: Plug the cooker directly into a wall outlet without sharing with high-draw appliances.
Test with smaller batch: Cook a smaller amount and compare cooking time to the manual.

When to call a technician: If times remain abnormally long, internal heater or sensor diagnostics are required.
