Programs end prematurely with food undercooked, but no error code is displayed.

Safety first: Ensure food is safe to eat; if in doubt, continue cooking until fully done.

• Verify program: Confirm you are using the correct Tower program and time for the recipe. Some programs are for reheating rather than full cooking.
• Observe behaviour: Watch the cooker during a test run with water to see if it unexpectedly switches to Keep Warm or powers off.
• Check power and wiring: Inspect the power cord and internal connections for looseness that could cause brief outages.
• Inspect sensors: If the cooker thinks the target temperature is reached too early, the NTC sensor may be misreading and should be tested or replaced.

If premature stopping continues with correct settings and stable power, a control board or sensor fault is likely and needs professional diagnosis.
