Why does my rice cooker smell musty or stale after storage?

A musty or stale smell after storage is usually caused by trapped moisture, not a serious fault. It often clears once the cooker is cleaned, aired and used correctly, but you should stop if the smell becomes burnt, chemical or electrical.

Try this first

1. Unplug the cooker and check that it has fully cooled.
2. Remove the lid and inner bowl, then wipe away any condensation or residue.
3. Leave the bowl and lid to air dry separately before reassembly.
4. Look for leftover rice, water in the steam exhaust, or damp storage conditions that could have caused the smell.
5. Run a normal cooking cycle with fresh water only if the appliance appears dry and undamaged.

What to expect

A light stale smell should fade after cleaning and airing. The manual notes that a slight odour can also occur the first time the appliance is used, and that this is temporary. A smell that gets stronger, smells burnt, or is accompanied by smoke is not normal.

Stop using it if

Stop using the rice cooker if the smell does not fade, if the base feels unusually hot, or if any residue appears scorched. If the issue remains unresolved or safe use is uncertain, contact the retailer or store where it was purchased.

Keeping the cooker dry between uses, especially around the bowl and lid, is the best prevention. The product information also shows removable inner bowls and detachable lids on several models, which makes thorough drying easier after cleaning.
