How to Find Your Pressure Cooker's Size and Model Before Ordering Parts

Find the rating label on the base

Start with the cooker’s base. Most electric pressure cookers carry a rating label on the underside or back of the base. It usually lists the model name or number, the voltage and the wattage. Unplug the cooker, let the heating element cool, and turn it over carefully, keeping the inner pot out so it doesn’t fall. Photograph the label with your phone so you have it when you shop.

The model name is more useful than the brand name. A brand can sell several model lines that share a quart size but not a lid, so two cookers with the same 6-quart pot can take different sealing rings. If the label is worn away, look for a model name on the front panel, inside the lid or on the box or manual. The control panel helps too: the buttons for Sauté, Slow Cook, Rice, Steam and Pressure Cook, and the display type, tell you a lot about the generation. Don’t guess from the look of the cooker, because different generations can look nearly identical.

Work out the quart size

The quart size is the filter that most parts listings use first. Look inside the stainless steel inner pot. Many have fill lines etched on the wall, often with a maximum line at two-thirds, and some are marked in quarts or liters. A stamp on the underside of the pot sometimes carries the capacity as well. If you only see liters, convert them: one quart is about 0.95 liters. So a 3-quart pot is about 2.8 liters, a 6-quart pot about 5.7 liters and an 8-quart pot about 7.6 liters.

The product name or manual may also state the capacity. If the numbers conflict, trust the markings on the pot, and then confirm with the model name from the label. A 5-quart and a 6-quart cooker can look alike, and parts for one aren’t always right for the other. Quart size matters because it sets the lid diameter, and the lid diameter sets the length of the sealing ring and the width of the pot rim.

Read the lid markings and check the sealing ring rack

Look at the lid next. The lid has the sealing ring rack around its rim, a metal flange with tabs that hold the ring, along with the float valve, the steam release pipe, the anti-block shield and the steam release handle. Some lids have text, arrows or symbols molded into them, such as sealing and venting marks or open and close arrows, which can help you match the generation. Note the shape of the steam release handle and how it attaches, because the designs vary.

Take the sealing ring out and look at it. Rings are made of silicone and usually have a stiff rim profile that clips into the rack. Check for any molded text on the ring, such as a size or model note, although not every ring has one. Measure the ring across its widest point with a ruler and write it down. Compare that to the diameter in a listing, but a worn ring can be stretched, and one that has soaked up chili or curry may have swollen slightly, so confirm with the model and quart size too.

A ring that sits loose in the rack, or that you have to force in, is the wrong size or the wrong profile.

Measure the inner pot

If you are replacing an inner pot, check the quart size and the model line first. Then measure the inner diameter at the rim and the depth of the pot. Note the handle design too, because some pots have small side handles that affect how the lid sits. The same rim diameter decides whether a steamer basket, trivet or springform pan will clear the walls, so the number is worth writing down.

When the base is warped, put a straightedge across the bottom of the pot to see whether it rocks. A pot that rocks may not touch the temperature sensor in the center of the cooker base, which can cause a burn warning or poorly cooked rice. Setting the pot into the base should show whether it sits level against the heating element.

A pot from a different quart size will not fit the base. Even a pot of the right quart size from another model line can differ at the rim.

Check the power cord and valve parts

For a replacement power cord, first confirm that your cooker takes a detachable one. Look at the connector end that goes into the base and read any rating printed on the cord label. Compare it with the wattage on the base label: a cooker drawing 1000 watts at 120 volts pulls roughly 8 amps, and the cord has to be rated for at least that. A damaged or loose cord, or one with bent prongs, should be replaced, not repaired.

For the steam release handle and float valve seal, note the model name, the lid’s generation and the shape of your current parts. Take a clear photo of the lid with the handle off, and one of the float valve from above and from the side. Ordering these from photographs alone is risky, because parts can look similar and fit differently.

A quick checklist before you order

Keep the old part until the new one is in and works. If you have to compare, put the two next to each other before you start cooking with the new one.

FAQ

Where is the model number on an electric pressure cooker?

Usually on a rating label on the underside or back of the base, and sometimes in the manual or on the box. The label commonly lists the model name, voltage and wattage. Unplug and cool the cooker before you turn it over.

What if my inner pot only shows liters?

Convert the number to quarts, because most parts listings use quarts. One quart is about 0.95 liters, so about 5.7 liters is a 6-quart pot. Then confirm the model name before ordering.

Can I match a sealing ring just by measuring it?

Measuring helps but isn’t enough on its own. A worn ring can be stretched, and the rim profile has to clip into your lid’s rack. Use the diameter as a cross-check against the model name and quart size in the listing.
