Multicooker heats but never reaches set temperature; food is undercooked and programs time out early.

Steps:

• Check that you are using the original Starfrit inner pot designed for your model. Third-party or warped pots may not transfer heat correctly.
• Inspect the bottom of the inner pot for warping or heavy residue. Clean thoroughly and replace the pot if it does not sit flat.
• Clean the heater plate surface inside the cooker to remove any burnt-on food or discoloration.
• Perform a water boil test: add 4 cups of water, select a high-heat program, and observe if the water reaches a vigorous boil within a reasonable time (10–15 minutes). If not, the heater may be weak.
• If you have tools and skills, test the heating element resistance and compare to specifications. A significantly higher resistance than normal indicates a weak element that should be replaced.
