Almost every part of an Instant Pot is dishwasher safe. This includes the stainless steel cooking pot, the lid, the steam rack, and the sealing ring.
The steam rack and inner pot are made of food-grade stainless steel, which means they are sturdy and won't rust or tarnish in the dishwasher. These are best placed on the top rack for cleaning.
The only part of an Instant Pot which isn’t dishwasher safe is the cooker base. This part plugs into your socket and is essential to heat your cooker, so it mustn’t get wet. To clean the cooker base, you can use a damp cloth.
