Why
Fissler pressure cookers are primarily made of high-quality 18/10 stainless steel, which is dishwasher safe and resistant to corrosion. However, the lid contains a silicone gasket (seal) that degrades under high heat and alkaline detergent, causing loss of elasticity and eventual leaks. The lid also has a spring-loaded valve and indicator pin with small moving parts that can be damaged by water jets or become clogged with detergent residue. Some models feature an aluminum core for heat distribution; aluminum is attacked by dishwasher detergents, leading to pitting and discoloration. Fissler's official care instructions recommend hand washing the lid and gasket to preserve the seal and valve mechanism, while the body can go in the dishwasher. Repeated machine washing of the gasket will cause it to harden and crack, compromising pressure retention. The outer surface may also develop minor etching over time from harsh detergents, but this is cosmetic.
How do you wash Fissler pressure cooker?
- Disassemble the lid: remove the silicone gasket, the valve assembly (if detachable), and the pressure indicator.
- Hand wash the gasket with mild dish soap and warm water; do not use abrasive sponges.
- Clean the lid body and valve parts with a soft cloth and mild detergent; rinse thoroughly.
- Wash the stainless steel pot body in the dishwasher on a normal cycle, or hand wash with soap and water.
- Dry all parts completely before reassembly; ensure the gasket is fully dry to prevent mold.
- Reassemble the lid, checking that the gasket sits evenly in its groove.
What happens if you put Fissler pressure cooker in the dishwasher?
If you put the entire Fissler pressure cooker in the dishwasher, the silicone gasket will be the first to fail. After one wash, you may notice the gasket feels slightly stiffer; after repeated washes, it will harden, crack, and lose its seal, causing steam to escape during use and preventing the cooker from reaching proper pressure. The valve and indicator pin may become clogged with detergent residue or mineral deposits, leading to inaccurate pressure readings or stuck valves. If your model has an aluminum-clad base, the aluminum may develop pitting and a white, chalky appearance due to chemical attack from dishwasher detergents. The stainless steel body itself will likely survive many washes with only minor water spotting or etching, but the functional components (gasket, valves) will degrade, making the cooker unsafe or ineffective. The damage is functional and permanent once the gasket is compromised.
Frequently asked questions
- Can I put the stainless steel pot body in the dishwasher?
- Yes, the stainless steel body is dishwasher safe. However, avoid using high-heat or sanitize cycles, and remove any aluminum-clad base from prolonged exposure to alkaline detergents.
- How often should I replace the silicone gasket?
- Fissler recommends replacing the gasket every 1-2 years, or sooner if it becomes hard, cracked, or stretched. Hand washing extends its life.
- Can the pressure cooker lid go in the dishwasher?
- No, the lid should be hand washed to protect the silicone gasket and the valve mechanism. Dishwasher heat and detergents can damage the seal and clog the valves.
- What water temperature can the Fissler pressure cooker withstand?
- The stainless steel body can handle high temperatures up to 260°C (500°F), but the silicone gasket is rated to about 200°C (392°F). Dishwasher temperatures (typically 50-75°C) are safe for the metal but harmful to the gasket over time.
