H1 or 'Hot' error appears; cooker refuses to start a new program immediately after finishing one.

Safety: Do not attempt to cool the cooker rapidly with water or ice; this can damage components.

Step 1 – Allow cooling:

• Open the lid (if safe and not under pressure) and remove the inner pot.
• Let the cooker sit unplugged for 20–30 minutes to cool.

Step 2 – Improve ventilation:

• Ensure the cooker is used on a hard, heat-resistant surface with at least 10 cm clearance on all sides.
• Avoid placing it under low cabinets where steam and heat can accumulate.

Step 3 – Sensor check (if H1 appears even when cold):

• Test the bottom and lid NTC sensors as described for E1/E2.
• Replace any sensor that reads out of range at room temperature.
