How to Replace Kuhn Rikon Pressure Cooker Handles and Knobs

Quick answer

Replacing a Kuhn Rikon pressure cooker handle or knob is a straightforward DIY job if you have the correct spare part for your model. Identify your cooker series and lid size first, then unscrew the old handle, fit the new one, and test the lid seal before cooking. Never force a mismatched handle or reuse a cracked knob.

Identify your cooker model and handle type before ordering

Kuhn Rikon pressure cookers use different handle and knob fittings depending on the series and lid diameter. Before you order any spare part, check the base of your cooker or the underside of the lid for the model name and diameter. The DUROMATIC® HOTEL Cuerpo olla 5.0 L. · Ø 28 cm, for example, uses a 28 cm body, and its handle and lid components are matched to that size. If you order a handle for a different diameter or series, the screw holes and steam vent alignment will not match.

Write down the model name, diameter, and any series number you can find. If the label is worn, measure the inside diameter of the cooker body with a ruler. A handle that looks similar but comes from a different series will often fit loosely or block the pressure valve, which is a safety risk.

Gather the right tools and work on a stable surface

You will usually need a screwdriver that matches the handle screws, a small container for loose parts, and a clean cloth. Some Kuhn Rikon handles are secured with a single screw under a cap; others use two screws or a bayonet fitting. Work on a table rather than a sink so small springs or washers do not disappear down the drain.

If your cooker has a separate lid handle and body handle, decide which one is faulty. A wobbly body handle often means the screw has loosened, while a cracked lid knob usually needs full replacement. Tightening a loose screw is a two-minute fix; a cracked knob should never be glued or patched.

Remove the old handle or knob safely

Let the cooker cool completely and confirm it is depressurized before you start. Open the lid, remove the gasket if it is in the way, and set it aside. Unscrew the handle or knob in a counter-clockwise direction, supporting the lid with your other hand so it does not drop. If the screw is stiff, apply a little food-safe lubricant and wait a few minutes rather than forcing it.

Keep the screws, washers, and any spacers in your container. On some models, the screw also holds a small metal bracket inside the lid; if that bracket falls out, note its orientation before you lose track of it. Never pry a handle off with a knife, as you can bend the lid rim and ruin the seal.

Fit the new handle or knob and check alignment

Offer the new handle up to the mounting points without tightening anything. Check that the screw holes line up, the handle sits flush against the lid or body, and any steam vent or locking pin moves freely. If the handle has a locking mechanism, test it now before you commit to tightening. A handle that binds or sits at an angle will not lock the lid correctly.

Once aligned, insert the screws and tighten them evenly. Do not overtighten, especially on plastic or Bakelite handles, as you can crack the mounting collar. The handle should feel firm with no side-to-side play. If it still wobbles, remove it and check that the washer or spacer is in the right position.

Test the lid and seal before cooking again

Refit the gasket if you removed it, then close and lock the lid without any food inside. The handle should engage smoothly and the lid should seal with normal resistance. If your cooker has a pressure indicator, check that it moves freely when you press it gently. A handle that prevents the lid from locking is a sign of a wrong part or incorrect fitting.

Do a water test: add a small amount of water, bring the cooker up to pressure, and then release the pressure according to your model's instructions. Watch for steam escaping around the handle or lid rim. If you see leaks or the handle feels loose under pressure, stop and recheck the fitting before using the cooker for food.

Step-by-step handle and knob replacement

1. 1. Confirm the model and part number: Check the base or lid for the series name and diameter, then match it to the spare handle or knob listing. Common mistake: ordering by appearance alone. Checkpoint: the part number or diameter must match your cooker exactly. If you cannot find a model label, measure the inside diameter before ordering.
2. 2. Cool, depressurize, and clear the workspace: Let the cooker cool fully, release all pressure, and remove the gasket if it blocks the handle screws. Common mistake: working on a hot cooker or over a sink. Checkpoint: the lid opens with no resistance and no hiss. A stable table and a small parts tray prevent lost screws.
3. 3. Unscrew the old handle or knob: Support the lid with one hand and unscrew counter-clockwise, keeping washers and spacers together. Common mistake: prying with a knife. Checkpoint: the screw turns without bending the lid rim. If the screw is stuck, use food-safe lubricant and patience, not force.
4. 4. Dry-fit the new handle before tightening: Align the screw holes and check that any locking pin or steam vent moves freely. Common mistake: tightening immediately and finding the handle binds. Checkpoint: the handle sits flush and the lid locks without extra effort. A dry fit takes seconds and prevents a cracked mounting collar.
5. 5. Tighten evenly and test for wobble: Tighten screws in small increments, alternating sides if there are two. Common mistake: overtightening plastic handles. Checkpoint: no side-to-side play when you gently push the handle. If it still wobbles, remove and check the washer or spacer position.
6. 6. Run a water pressure test: Lock the empty lid, bring a small amount of water to pressure, and release according to your model's instructions. Common mistake: skipping the test and cooking immediately. Checkpoint: no steam leaks around the handle or rim. Any leak or looseness means stop and refit before cooking food.
