Press the cook lever, walk away, and come back to find it popped up to warm with the rice still hard? A rice cooker button that clicks up too early is reading the pot as done before it is, and the cause is usually easy to spot.
Here is why the button pops up early and how to fix it.

Why the Button Pops Up Early
The pot not seated flat on the heating plate.
Too little water, so the plate heats past the trigger point fast.
Debris under the pot lifting it off the sensor.
A weak magnet or thermostat switching at the wrong temperature.

How to Fix a Button That Pops Up Early
Seat the pot. Set the inner pot flat and give it a gentle turn so it rests fully on the plate.
Clean the plate. Remove crumbs or grains between the pot and the heating plate.
Add enough water. Use the correct ratio so the cooker runs a full cycle.
Test the switch. If it still trips early, the magnet or thermostat is likely weak.
Pro Tip: A single grain of rice stuck between the pot and the plate can fool the sensor into switching off early. A quick wipe of both surfaces fixes many early trips.
If the pot seats flat, the plate is clean, and the water is right but it still pops early, the thermostat magnet has weakened. Replacing the cooker is usually the sensible route.
