There can be other reasons why the rice cooker isn’t performing correctly, Many times, it has to do with power interruptions to the rice cooker during the cooking cycle or a mechanical issue. Listed below are the 9 most common problems encountered and the solution(s) for those issues:

  1. Keys do not work – Check to see if the rice cooker is plugged in properly and the inner pan inserted correctly. Also, check if the Keep Warm indicator is lit; if so, press Reset Key and then press Cook/Reheat Key.

Maintenance And Upkeep Of Your Zojirushi Rice Cooker

A rice cooker, like all kitchen appliances, requires cleaning and maintenance to stay in peak condition. The use of proper cleaning materials and equipment can help extend the life of your rice cooker for many years. I’ve outlined the following recommended cleaning methods below:

  1. Rice cooker inner lid, pan, and serving spatula – Soak the parts in warm water and then wash off using mild dish detergent or soap and a soft washcloth or sponge.
  2. Outer lid surface and interior body surfaces – Clean using a soft, dampened cloth.
  3. Electrical cord and plug – Wipe with a soft, dry cloth.
  4. Control Panel – Wipe with a soft, dry cloth.
  5. Exterior Surface – Clean using a well-wrung dampened cloth using mild detergent and then dry off with a towel.
  6. Heating Plate and Center Heat Sensor – Clean using a well-wrung dampened cloth using mild detergent and then dry off with a towel. Use caution when clearing any debris or rice per the below instructions.

*Please Note – If grains of rice are found under the heating plate while cleaning, use a bamboo chopstick or plastic knife to remove the debris. Do not use anything metallic as this may damage the heating element or cause rust to form. If the rice has been burned onto the heating plate, lightly polish the surface using a #320 sandpaper soaked in water. Wipe away any remaining debris with a soft, dampened cloth.
