My zojirushi electric air pot has significant calcification buildup inside. how do i clean it out?

Boil Vinegar water or lemon juice water (liquid, not fresh lemon) to remove calcium buildup.

CALCIF usually indicates "calcification" which is a buildup of calcium and other minerals. I don't believe you would normally see this indication on a microwave oven. Coffeemakers often indicate mineral buildup by indicating "DESCALE" or similar.

Descaling or removing mineral deposits in a coffeemaker usually requires running the coffeemaker with white vinegar instead of water, and no coffee ground or filter. Three or four "brewings" is usually all that is needed to remove the deposits. Simply run several more brewing cycles of clean water to rinse all the internal components of any vinegar and the job is complete.

If this answer isn't applicable - please tell me model number of the appliance that is displaying the CALCIF message, otherwise, please rate my reply "4 thumbs up" if it was helpful Thanks!

Replacement parts may be ordered from our online Zojirushi Parts Store or by calling the Customer Service Department at 800-733-6270, M-F, 8:00 a.m. to 5:00 p.m. PST.

Make sure you have your model number ready when calling.

Run a pot of half water and half vinegar through the coffee pot and you may need to repeat this process a couple times to get all the calcium buildup cleaned out of the pot. Hope this helps.

I have zojirushi 4L (model: CD-LCC). I noticed that the bottom of the pot have some stain which are looked like "corrosion". What should I do? How to remove it? Please help.

Thank you

Got greasy white stuff floating inside the kettle, any idea where this comes from? And how to eliminate it besides getting a new one. This unit is over 5 years old. Thanks.

Solution, take the zojiroshi apart and put the element in the bottom of a travel mug.
