Why does my rice stick to the bottom of the pot?

Three causes: the inner pot non-stick coating is degraded (metal utensils, abrasive scrubbing, or dishwasher damage have worn through the coating); insufficient water (the bottom cooks dry before the top absorbs fully); or the heating plate has a hot spot from buildup. Fix: if the coating is visibly peeling or scratched through to the aluminum, the inner pot needs replacement (available from the manufacturer). For insufficient water: add 1 to 2 tablespoons more per cup. For heating plate buildup: clean with a damp cloth (steps 3 and 5 above).

Why does my rice cooker boil over?

Overfilling: either too much rice (above the max line) or too much water (above the water line for the amount of rice). For starchy rice varieties (short-grain Japanese rice, glutinous rice): add 1 teaspoon of vegetable oil to the water, which reduces foam formation and prevents boil-over without affecting taste. Also: clean the steam vent (step 5) — a clogged vent increases internal pressure and causes earlier boil-over.

How often should I clean the inner pot and lid?

Inner pot: after every use — hand wash with soft sponge, mild soap. Never soak overnight; the non-stick coating edge can absorb water. Lid and steam vent: weekly if cooking daily, or every 5 to 10 cycles. The gasket ring: remove and wash monthly. Heating plate (exterior, not submerged): monthly or when visible residue is present. These intervals maintain both cooking performance and inner pot lifespan.

Rice Cooker Not Cooking Properly: 8 Causes and Fixes

Undercooked, mushy, or stuck-on rice feels like a sign the cooker is failing.

Usually it isn't. It's a specific, fixable cause hiding behind a generic symptom.

Water ratio explains most complaints, but a worn lid seal, a clogged steam vent, or the wrong measuring cup can each produce the exact same frustrating result.

This guide walks through eight causes in order, starting with the fix that resolves the majority of cases, so you can troubleshoot before assuming the unit needs replacing.

The Two Most Common Problems

Mushy or undercooked rice: water ratio and resting time cover the majority of rice texture complaints. Calibrate the water ratio (steps 1 and 4) and add a 10 to 15 minute resting period after the ready signal (step 6).

Rice sticking to the pot: non-stick coating condition and water ratio. If the coating has worn through: replace the inner pot. If it is intact but rice still sticks: add a small amount more water and brush the inner pot with vegetable oil before each use.
