The Justice Department and the Consumer Product Safety Commission sued two Chinese manufacturers this week over Lakkzoom immersion water heaters tied to 235 reported fires, the agency's first use of its strongest court authority since 1987. It is a different product than the tank or tankless unit in your basement, but the failure mode behind it points at a risk every homeowner's real water heater can develop too.
What the Government Actually Sued Over
The Department of Justice, working with the Consumer Product Safety Commission, filed a complaint this week against two China based companies behind the Lakkzoom brand. Cixi Miaojie Electrical Appliance is named as the manufacturer, while Changsha Jiayi Tianzhuo Trading is named as the seller that moved the units through US marketplaces. The complaint targets model numbers including 1500W, 2000W, HT1500W (also sold as MJ-R13), and HT2000W, small plug-in heating rods meant to be dropped directly into a cup, bucket, or pot of water.
Investigators found the heaters lack the safety features that similarly priced competitors build in, including a shutoff that trips when the heating element is not fully in contact with water or reaches an unsafe temperature. Without that protection, CPSC says the units can ignite within minutes if they are run dry or only partially submerged, and the agency has logged 235 reports of fires tied to the product since it hit the market in September 2022.
This is only the second time the Commission has gone to court under Section 12 of the Consumer Product Safety Act in nearly forty years, a legal path reserved for products the government considers an imminent and unreasonable risk of death or serious injury. The lawsuit asks a federal court to order a mandatory recall and full refunds, a step the agency normally tries to avoid by negotiating a voluntary recall first.
Why an Immersion Heater Is Different From the Water Heater in Your Basement
It is worth being precise about what got recalled here. An immersion heater is a small, inexpensive gadget, often marketed for instant hot tea, dorm rooms, or an RV, that heats water by direct contact rather than sitting inside a tank connected to your home's plumbing. It is not the same category as the 40 or 50 gallon tank unit in a utility closet or the tankless unit mounted on a wall, and Plumbarama does not install or service Lakkzoom style immersion gadgets.
That distinction matters for anyone worried this recall applies to their household system. It does not, directly. Where it does matter is if a Lakkzoom unit, or something like it, is sitting in a garage, a camper, a dorm fridge, or a break room at a small business in New Jersey or Pennsylvania. Those are the places worth a quick look at the model number and brand printed on the device or the receipt.
The Real Overlap: What Happens When Any Water Heater Runs Dry
The mechanism behind this recall, a heating element that keeps drawing power without enough water around it to dissipate that heat safely, is not unique to a ten dollar gadget. It is a known failure category across water heating equipment generally. In a standard household tank water heater, sediment that settles at the bottom over months or years can bury part of the heating element or burner assembly, forcing it to work harder against a layer of mineral buildup instead of open water.
A failing thermostat or high-limit switch can create a similar problem in a name brand tank unit, letting the system keep heating past a safe point instead of shutting off. These are not the fire-in-minutes scenario CPSC described for Lakkzoom, tank units are built with more layers of protection, but the underlying lesson translates directly: a water heater that is not maintained is a water heater whose safety margins are shrinking without anyone noticing until something fails.
What NJ and PA Homeowners and Businesses Should Do This Week
Start with the easy part. If a Lakkzoom brand immersion heater, or any unbranded immersion rod bought cheaply online, is anywhere in the house, garage, or workplace, CPSC's guidance is to stop using it immediately regardless of how the lawsuit plays out in court. There is no safe repair for this specific hazard, and the government is not waiting on a voluntary fix.
Then take care of the part that is easy to put off. Most NJ and PA households have never had their actual water heater flushed or inspected, and sediment buildup, a stuck thermostat, or a near-end-of-life anode rod tend to show up as a rumbling sound or a lukewarm shower long before they become a real problem. With commercial units already facing an October 2026 federal efficiency deadline pushing more replacements industry-wide, this is a reasonable week to have a licensed tech actually look at the unit heating your home's water rather than assume it is fine because it has not failed yet.
Plumbarama's licensed NJ and PA technicians can flush sediment, test the thermostat and high-limit switch, and flag a unit that is quietly heading toward the kind of overheating risk this recall put a spotlight on, before it turns into an emergency call. Our line is open 24/7 for anything that cannot wait.

6 Warning Signs Your Real Water Heater Is Heading Toward the Same Kind of Trouble
None of these are the fire-in-minutes hazard CPSC described, but each one is a sign a tank or tankless unit's safety margins are shrinking.
- Rumbling or popping sounds: Usually sediment settled at the bottom of a tank, insulating the heating element and forcing it to run hotter and longer than it should.
- Frequent shutoffs or resets: Short-cycling can point to a failing thermostat or high-limit switch that is not regulating temperature the way it is supposed to.
- Discolored or metallic-smelling hot water: Often a sign of corrosion inside an aging tank or a spent anode rod that is no longer protecting the metal.
- A pilot or burner that will not stay lit: Can point to a failing thermocouple or gas control valve worth a professional look before it gets worse.
- Scorching, melted plastic, or a burning smell near the unit: Treat this as urgent. Shut off power to the unit and call a licensed plumber the same day.
- A unit past 10 to 12 years old with no recent inspection: Most tank water heaters are not built to run indefinitely without a checkup, and age compounds every other issue on this list.
Frequently asked questions
- Does this recall affect the water heater in my house?
- Not directly. The recall covers small plug-in immersion heaters sold under the Lakkzoom brand for heating a cup or bucket of water, not the tank or tankless units connected to a home's plumbing. If you own a Lakkzoom device, stop using it regardless.
- What should I do if I own one of the recalled heaters?
- CPSC says to stop using it immediately. The DOJ's lawsuit is seeking a court-ordered mandatory recall and full refunds, but the agency's safety guidance not to use the product stands regardless of how that litigation resolves.
- Is this the same kind of hazard as a carbon monoxide risk?
- No. This recall is about a fire hazard from a heating element running dry or partly submerged. Carbon monoxide risk is a separate category tied mainly to combustion appliances like gas furnaces or certain gas water heaters with venting problems.
- How do I know if my actual water heater needs attention?
- Watch for rumbling sounds, short-cycling, discolored water, a pilot that will not stay lit, or a unit older than 10 to 12 years that has never been inspected. Any of those is a reasonable reason to schedule a checkup.
