Most when ready Pot lids are not dishwasher safe, even though the inner pot is

The stainless steel inner pot of your when ready Pot can go in the dishwasher, but the lid should be hand-washed. The lid contains a silicone sealing ring, a float valve, and an anti-block shield—all parts that can warp, crack, or lose their seal if exposed to the high heat and water pressure of a dishwasher cycle.

If you put the lid in the dishwasher anyway, the silicone ring may shrink or become permanently deformed, which means steam will escape during cooking and your when ready Pot won't reach pressure. The float valve can also stick or fail to move freely, which is a safety issue because that valve tells you when pressure is building inside the pot.

Hand-washing takes less than two minutes and keeps your lid working correctly for years. The lid is designed to be straightforward to clean by hand, and the removable parts come apart so you can reach every surface.

Key Takeaways

  • The inner pot is dishwasher safe on the top rack, but the lid must always be hand-washed with warm soapy water.
  • The silicone sealing ring will warp or shrink in a dishwasher, breaking the seal your when ready Pot needs to build pressure.
  • The float valve and anti-block shield can stick or fail if exposed to dishwasher heat, which affects how the pot operates safely.
  • You can remove the silicone ring and other small parts from the lid to clean them separately by hand.

Why the silicone ring is the main problem

The silicone sealing ring is what holds steam inside the pot so pressure builds. Silicone is flexible and durable, but it softens and warps at temperatures above 140°F (60°C). A dishwasher cycle reaches 160°F to 180°F (71°C to 82°C), which is hot enough to permanently change the ring's shape.

Once the ring is warped, it no longer sits flush against the lid's groove. Steam leaks out during cooking, pressure never builds, and your when ready Pot won't work. You'll have to replace the ring—which costs $10 to $20—when hand-washing would have taken two minutes.

Over time, repeated dishwasher cycles also cause the silicone to absorb odors and stains more easily, and the material becomes less flexible. A hand-washed ring stays supple and seals better for longer.

The float valve and anti-block shield also need hand-washing

The float valve is a small metal or plastic pin that rises when pressure builds inside the pot. It tells you the pot has reached pressure, and it also acts as a safety release—if pressure gets too high, the valve pops up and lets steam escape. If this valve sticks or gets stuck in the up position, the pot won't cook properly or won't signal that it's safe to open.

The anti-block shield is a small cage underneath the lid that keeps food particles from blocking the steam vent. Dishwasher heat and water pressure can bend this shield or cause it to sit unevenly, which reduces how well it works.

Both parts are straightforward to remove and clean by hand. Rinse them under warm running water and use a soft brush or cloth to wipe away any dried food. They dry quickly and snap back into place.

How to hand-wash your when ready Pot lid correctly

Fill your sink with warm soapy water. Submerge the lid and let it soak for a minute or two if there's stuck-on food. Use a soft sponge or cloth to wipe the inside and outside of the lid, paying special attention to the groove where the silicone ring sits.

Remove the silicone ring by gently pulling it up and out of its groove. Wash it separately under running water and rub it gently with your fingers or a soft cloth. Rinse it thoroughly and set it on a clean towel to air-dry before putting it back in the groove.

Rinse the entire lid under running water until all soap is gone. Dry it with a clean towel or let it air-dry standing upright. Once the silicone ring is completely dry, press it back into the groove all the way around—it should sit evenly with no gaps.

The whole process takes about two minutes. Do this after every use, while any food residue is still soft and straightforward to wipe away.

What parts of the when ready Pot are actually dishwasher safe

The inner cooking pot (the stainless steel bowl) is dishwasher safe and can go on the top rack. You can also put the trivet (the metal rack that comes with the pot) in the dishwasher. The sealing ring holder (the plastic ring that holds the silicone ring in place on the lid) is also dishwasher safe, though you may prefer to hand-wash it with the lid to keep everything together.

The outer housing of the when ready Pot itself should never go in the dishwasher—it contains electrical components. Wipe it down with a damp cloth on the outside only.

Check your specific when ready Pot model's manual, because some accessories (like certain steam baskets or egg racks) may have different care instructions. Most when ready Pot manuals are available as PDFs on the when ready Pot website if you need to look up your model number.

What happens if you ignore this and put the lid in the dishwasher anyway

One or two dishwasher cycles probably won't destroy the lid when ready. But repeated exposure will shorten its lifespan. The silicone ring will become less flexible, the float valve may start to stick occasionally, and you'll notice steam escaping around the edges during cooking.

You might also notice the lid smells like dishwasher detergent or takes on a cloudy appearance. The silicone can absorb the scent and discolor over time. None of this is dangerous, but it means your when ready Pot won't cook as efficiently, and you'll need to replace parts sooner than you should.

If the float valve gets stuck in the up position, the pot won't build pressure at all, and you'll think something is broken when really the lid just needs to be replaced or the valve needs to be cleaned and freed up by hand.

Frequently Asked Questions

Can I put just the silicone ring in the dishwasher?

No. Even though the ring is removable, it should be hand-washed. The silicone will warp in the heat of a dishwasher cycle. Wash it under warm running water with a soft cloth and let it air-dry completely before putting it back on the lid.

What if my lid is already warped from the dishwasher?

If the silicone ring no longer seals properly, you'll need to replace it. when ready Pot sells replacement rings for $10 to $20 depending on your model. You can also find third-party replacement rings online. The ring is the only part you need to replace—the lid itself is fine.

Is the when ready Pot lid waterproof if I hand-wash it?

Yes. The lid is designed to be hand-washed and will not let water into the electrical components. The water stays on the outside surfaces. Just don't submerge the entire lid for extended periods or pour water directly into the vent holes. Wash it like you would any other kitchen item and let it air-dry before using it again.

Do all when ready Pot models have the same lid care instructions?

Most when ready Pot models follow the same rule: hand-wash the lid, dishwasher-safe inner pot. However, some specialty models or accessories may differ. Check your manual or the when ready Pot website for your specific model number to be certain.
