Latest Mueller UltraPot Pressure Cooker Lawsuit Developments

March 2026

March 27, 2026 – Court records reflected continued activity in Nguyen v. Amazon.com Inc., a federal product-liability case involving a Mueller pressure cooker. The case concerns allegations that a Mueller Electric Pressure Cooker allowed its lid to be removed while pressure remained inside the unit. [1]

January 2026

January 15, 2026 – A Virginia woman filed a federal lawsuit against Amazon alleging that a Mueller Electric Pressure Cooker, model ML100A-M01, allowed its lid to rotate and open while still pressurized. The complaint alleges that hot contents were forcefully ejected from the cooker and caused serious burn injuries during a February 17, 2024 incident. [2]

The complaint alleges that the cooker’s interlock did not prevent the lid from opening while pressure remained inside. It also asserts product-liability and warranty claims and alleges noncompliance with specified safety standards.

What Is the Mueller UltraPot Pressure Cooker?

The Mueller UltraPot is a 6-quart electric pressure cooker and multi-cooker designed to cook food under steam pressure. Its instruction manual describes programmed cooking functions and high- and low-pressure settings of approximately 50–60 kPa and 30–40 kPa.

The appliance includes functions for soup, poultry, meat and stew, rice, beans, multigrain, steaming, yogurt, sautéing, slow cooking, and pressure cooking. It also enters a keep-warm mode after certain cooking cycles are complete.

The manual lists several safety components, including a lid safety lock system, pressure-limiting valve, pressure-relief device, anti-block cover, lid safety switch, pressure-control device, temperature protections, and thermal protection. [3]

How Does the Mueller UltraPot Build and Release Pressure?

Electric pressure cookers heat liquid inside a sealed pot, creating steam that raises internal pressure and cooking temperature. When pressure rises inside the Mueller UltraPot, the float valve is designed to move upward and the lid is intended to remain locked.

Pressure must be released before the lid is opened. The manual describes natural pressure release and quick release and instructs users to wait until the float valve drops before attempting to remove the lid.

The manual also warns users not to force the lid open if it remains tight. Consumers are instructed to keep their hands and face away from the pressure-limiting valve when releasing steam because of the risk of scalding.

What Problems Can Occur With Pressure Cookers?

Pressure cookers can contain extremely hot steam, liquid, and food under pressure. If a lid, locking mechanism, valve, seal, or other safety component does not function properly, pressurized contents can escape suddenly and cause serious injuries.

Potential pressure cooker problems may include:

• A lid that opens before internal pressure has been fully released
• A locking mechanism that does not keep the lid secured
• A float valve that does not accurately indicate remaining pressure
• A blocked or malfunctioning pressure-release valve
• A damaged, misplaced, or deteriorated sealing ring
• Overfilling that interferes with pressure-control components
• Unexpected release of steam, liquid, or food
• Failure of electrical or temperature-control components

These hazards are not unique to one brand. CPSC recalls involving other pressure cookers have documented situations in which lids could be opened while pressure remained inside or hot contents could escape unexpectedly, creating a burn hazard.

Why Is Opening a Pressurized Cooker Dangerous?

Pressure inside a cooker allows liquid and food to reach temperatures above normal boiling conditions. If the lid is removed before pressure has dissipated, the sudden pressure change can cause hot food, liquid, and steam to erupt from the pot.

This type of release can expose the face, chest, arms, hands, and other areas of the body to scalding material. Severe incidents can result in second- or third-degree burns, scarring, infection, surgery, skin grafts, or rehabilitation.

CPSC has identified premature lid opening as a serious hazard in recalls involving other brands. In 2025, for example, SharkNinja recalled Foodi pressure cookers after reports that pressure-cooking lids could be opened during use, allowing hot contents to escape and causing serious burn injuries. [4]

What Does the Mueller UltraPot Manual Say About Safety?

The Mueller UltraPot manual warns that improper use can result in scalding injuries. Users are told not to open the cooker until pressure has been released and to avoid direct exposure to steam when operating the pressure-release system.

The manual states that a raised float valve indicates the cooker is pressurized and the lid is locked. After pressure is released, the float valve should drop before the lid is opened.

The manual also warns against overfilling. Food and liquid generally should not exceed two-thirds of the inner pot, while expanding foods such as rice, grains, beans, and dried vegetables should not exceed one-half of the pot.

What Does the Mueller UltraPot Lawsuit Allege?

The January 2026 complaint involves a Mueller Electric Pressure Cooker identified as model ML100A-M01. According to the plaintiff, she purchased the cooker through Amazon and suffered serious burn injuries on February 17, 2024.

The lawsuit alleges that the lid could be rotated and removed even though pressure, heat, and steam remained inside the cooker. When the lid was removed, the complaint claims that the remaining pressure caused scalding-hot contents to be projected from the unit and onto the plaintiff.

The plaintiff alleges that the incident resulted from a defective interlock mechanism and claims that safer alternative designs could have prevented the lid from opening while pressurized. These allegations have not been established as factual findings by a court.

Has the Mueller UltraPot Pressure Cooker Been Recalled?

No CPSC recall has been identified for the Mueller UltraPot Pressure Cooker as of September 2026. The existence of a product-liability lawsuit does not itself mean that a product has been recalled or that a government agency has determined the product is defective.

A recall is also not required for an injured consumer to seek legal advice about a potential product-liability claim. Any case would depend on the specific cooker involved, the alleged malfunction, evidence from the incident, the injuries suffered, and applicable state law.

Who May Be Affected?

Consumers who used a Mueller UltraPot or another Mueller electric pressure cooker and experienced unexpected lid movement, premature opening, steam release, or ejection of hot food or liquid may warrant further review. The most relevant incidents are those involving physical injuries, particularly burns or scalding that required medical treatment.

People who experienced an incident should consider preserving the cooker, lid, gasket, pressure valves, packaging, purchase records, photographs, medical records, and other documentation. Evidence showing the condition of the appliance after the event can be important in evaluating whether an alleged malfunction contributed to an injury.

What Injuries Can Pressure Cooker Accidents Cause?

The most serious injuries associated with pressure cooker incidents typically involve thermal burns and scalding. Hot steam, liquids, oils, sauces, or food expelled under pressure can contact large areas of the body within seconds.

Potential injuries may include:

• First-, second-, or third-degree burns
• Burns to the face, neck, chest, arms, or hands
• Eye injuries
• Permanent scarring or skin discoloration
• Infections and wound complications
• Nerve damage or reduced range of motion
• Need for skin grafts or reconstructive treatment
• Emotional distress following a severe burn incident

The seriousness of a burn depends on the temperature of the material, the duration of exposure, the body area involved, and the depth of tissue damage.

Who May Be Liable for a Defective Pressure Cooker?

Potential liability in a pressure cooker case depends on the facts and applicable state law. Companies involved in designing, manufacturing, importing, distributing, or selling a product may potentially be evaluated when an alleged defect causes an injury.

Possible legal theories may include defective design, manufacturing defect, failure to warn, negligence, or breach of warranty. A plaintiff generally must establish that a legally actionable defect or other wrongful conduct contributed to the injury.

In the January 2026 Mueller lawsuit, Amazon is the defendant identified in the complaint. The plaintiff alleges that Amazon marketed, imported, distributed, and sold the pressure cooker at issue and asserts warranty and product-liability claims against the company.

Compensation in a Mueller Pressure Cooker Case

Depending on the circumstances, a pressure cooker injury claim may seek damages for medical expenses, lost income, pain and suffering, scarring, disfigurement, and other losses recognized under applicable law. The types of damages available vary based on the facts, jurisdiction, and evidence.

Compensation amounts vary by case. Past results do not guarantee future outcomes.

Do I Qualify for a Mueller UltraPot Pressure Cooker Claim?

• Did you use a Mueller UltraPot or Mueller electric pressure cooker?
• Did the lid open, rotate, unlock, or separate while pressure remained inside?
• Did hot steam, food, or liquid escape from the cooker unexpectedly?
• Did you suffer burns or another injury that required medical treatment?

Answering yes to one or more questions does not automatically establish a lawsuit. An attorney can review the product model, incident circumstances, medical records, photographs, purchase information, and applicable legal deadlines to determine whether a claim may warrant further investigation.
