Multicooker takes excessively long to build pressure or never reaches pressure; steam constantly escapes from lid.

Safety first: Do not touch escaping steam. Turn off the cooker and allow it to depressurize naturally.

• Inspect sealing ring: Remove and examine the silicone ring. Replace if cracked, stretched, or hardened.
• Clean lid rim and pot edge: Wipe both surfaces to remove food residue that can prevent sealing.
• Check steam valve: Disassemble the steam release valve and anti-block shield as per Bosch instructions. Clean all parts and reassemble correctly.
• Test with water: Run a short pressure cycle with only water. If steam still leaks visibly from the lid edge or valve, replace the sealing ring and, if needed, the steam valve assembly.
