The Hidden Costs of Dishwasher Leaks

Despite dishwashers being a likely source of leaks, there has been no adequate existing solution 

Dishwasher leaks are very frequent in commercial and domestic kitchens, whether they are built-in or stand-alone units. High volume, high temperature, and high-pressure water means that leakscan be catastrophic and costly. Leaks are also hard to spot, because you don't usually see water under the dishwasher, but the water handling is typically at the back of the unit, and the machine is mounted close to the ground. Water's corrosive potential combined with expensive finishes and infrastructure in kitchens make leaks expensive.

The motivation to mitigate the costs of a leak and the ultimate bearer of those costs depends on the setting (commercial or domestic), whether there is a service or warranty plan in place, and the specific insurance products that do, or do not govern the performance of the device. These dynamics are discussed in detail in the route to market section below. In general though, by detecting a leak under a dishwasher you create value for either the homeowner, by mitigating the loss incurred with a leak, the insurer, by reducing the payout associated with a 'sudden and accidental leak', or with a service provider who can improve machine uptime by spotting leaks faster.

But regardless of the route to market, all parties are concerned with the same physical phenomenon, a leak from a dishwasher, for which there is no adequate existing detection solution. An easy-to-install, physically thin solution is required.

The overall market is projected to grow robustly

The dishwasher market will grow due to busy schedules, long working hours, urbanization, and increasing awareness about hygiene and cleanliness. The global dishwasher market size is expected to reach USD 10.23 billion by 2025, according to a new report by Grand View Research [ref], Inc. It is anticipated to register a CAGR of 7.2% from 2019 to 2025.

The built-in segment is anticipated to grow slightly faster than the overall market growth (7.8% CAGR from 2019 to 2025). These devices tend to have more advanced features, smaller sizes and coincide with the trend of modular kitchens. The growth of built-in devices and modular kitchens is very well-aligned with LAIIER's product roadmap and vision, making it easier for us to scale.

Regionally, China is the largest market for home appliances, followed by the EU and the United States [ref]. China is expected to maintain its position throughout the market and will experience faster growth in dishwasher sales in the next decade.

Though dishwashers are often thought of as consumer devices, 60% of the global dishwasher revenue went to commercial devices, where a service contract is frequently present [ref].

Water Damage Facts

Water damage to homes and business represents a huge cost to property owners, tenants and insurers every year. Whether the source of water is from a pipe, or equipment, leaks are troublesome, costly, and much more common than you might think [ref].

  • 14,000 homeowners deal with water leak emergencies every day in the US
  • 37% of homeowners have suffered losses due to water damage
  • Insurance companies pay out $2.5 billion each year due to water damage in the US
  • The average domestic escape of water damage claim is $6,965
  • 250 Gallons of water can leak from a crack in a 1/8" pipe in a single day
  • According the to the EPA water leaks in the US waste more than 1 trillion gallons each year [ref]

The problem: sudden and gradual leaks in awkward places

The problem is an "Escape of Water" event from a dishwasher, which we will refer to here as a leak. It is important to note that "Escape of Water" is different from flooding. Escape of Water is defined as an event where the water comes from inside the structure according to the ABI [ref].

There are six common sources of leaks on a dishwasher [ref]. The supply hose, the return hose, the appliance door, the appliance drain, an un-level dishwasher, and a defective pump. All of these can result in a small, gradual leak or a sudden and accidental leak. Most leaks will be exacerbated during dishwasher use. And frequently the troubleshooting of the leak involves running the machine to produce a leak. Eventually, all of the leaks will manifest with water underneath and below the dishwasher [ref].

A dishwasher leak can cause water damage in a variety of ways to a variety of different elements of your kitchen. Many materials are susceptible to damage after a dishwasher leak including tile, wood, laminate, electrical wiring, drywall, wallpaper, and paint.


The LAIIER solution: a uniquely thin sensor

As detailed, water leaks from dishwashers can be costly- not only dealing with appliance repairs but also their secondary damage. Mitigating these large costs is therefore crucial and the key lies within rapid, early detection of water leaks. The compactness of built-in dishwashers are only getting more popular suggesting the restricted space for water detection devices. LAIIER, with our commercial water leak detector sensors can adapt to these limited spaces, detecting leaks extremely early in the process. Our sensors can furthermore notify homeowners promptly via our Surface to Cloud™ platform that uses LoRaWAN- an ideal network for wireless, power-efficient communication.
