Sudden dishwasher leaks can leave homeowners scrambling, especially when water damage starts to occur on the floors. 26% of Canadians experience water damage incidents in their homes each year. Because leaky dishwashers can quickly turn into a nightmare, many Canadians wonder: Will my home insurance cover damage from a leaking dishwasher?

This article will answer all the questions you have about whether your home insurance suffices, why dishwashers leak in the first place, and what you can do to avoid denied insurance claims.

Leaking Dishwashers At a Glance

  • Some dishwasher leaks are covered by insurance – it depends on what caused the damage and whether it was preventable.
  • Dishwashers may leak for several reasons, including faulty latches, improper installation, and general wear and tear.
  • Dishwasher leaks can occur from the door and from the bottom. Where the leak originates can influence whether insurance covers damage or not.

Are Damages from a Leaking Dishwasher Covered by Insurance?

Yes, your home insurance can cover damages from a leaking dishwasher if the water leak is sudden and accidental. Tenant insurance can also cover water damage. Many insurers cover “water escape” from plumbing systems, which occurs when your dishwasher suddenly bursts or overflows unexpectedly. 

However, this coverage has limitations and exclusions. For example, most policies won’t cover gradual leaks caused by slow deterioration, corrosion, or negligence, as homeowners have ample time to repair their systems. Instead, these are considered poor maintenance issues rather than an accident.

In addition, your policy won’t cover the cost of repairing or replacing the appliance itself. It will cover the resulting property damage, which might encompass warped floors or water-damaged drywall.

Why is My Dishwasher Leaking?

There are many reasons a dishwasher might leak, and identifying the cause is vital to repairing it. Here are some common culprits for a leaking dishwasher: 

Worn or damaged door gasket:

Over time, the rubber seal around the dishwasher door may wear and tear, allowing water to seep out during washing cycles. Even the smallest gaps can break the watertight seal and may require a replacement.

Faulty latch or hinge:

Misaligned or broken latches can also cause water to leak out from the front. Avoid overloading your washer to ensure the door closes fully.

User error:

Sometimes, using the wrong detergent can create excess suds that cause leaks and overflows. Overloading the dishwasher can also block the spray arms, causing water to push past the seals.

Loose or cracked hoses:

If the hose clamps on your supply lines are loose, cracked, or split, leaks can occur underneath your washer. It’s best to replace old hoses regularly or use tougher materials, such as braided metal. 

Clogged filters or drains:

If your filter is completely clogged with food debris, water might accumulate at the bottom and leak out. If the drain path is also blocked, wastewater can travel back up and clog the dishwasher every time it tries to drain.

Internal cracks or damage:

Although less likely, extreme damage to your dishwasher can cause cracks in the interior tub, allowing water to escape internally.

Dishwasher Leaking from the Bottom vs. Door: Why Insurers Treat Them Differently

Dishwashers typically experience two types of leaks: 

  1. From the front door
  2. Underneath

Again, whether your insurer will provide coverage for water damage depends on the cause of the leak. Leaks from the bottom vs. leaks from the door imply very different causes.  

You’re more likely to file a claim successfully if your dishwasher leaks from the bottom, as this implies a sudden internal failure difficult to foresee. For example, the water supply line might burst, a hose may rupture, or a pump may fail suddenly.  

If there are no prior signs of a problem, most insurers will deem this incident accidental and cover it regardless of age. 

When water leaks from the dishwasher door, it usually indicates user error, a gradual decline, or an avoidable issue. Door seal leaks are often the result of long-term wear and tear or negligence, which may lead insurers to conclude that you “failed to maintain” the machine. 

When you file a claim for a leaking dishwasher, an adjuster or contractor will determine the cause of the leak and whether this was due to long-term wear or an improperly installed part. Sometimes, there are gray areas, such as a door latch suddenly snapping. 

Always document when and how the leak occurred and provide as much information as possible.

How to Install a Dishwasher (The Claims-Prevention Edition)

Installing your dishwasher correctly goes a long way in preventing leaks and future claims. Don’t give your insurer grounds to deny a claim by following these helpful tips.

Use the Right Connectors

If your dishwasher is new, always use the water supply provided by the manufacturer. If you’re replacing your connector, consider upgrading to a steel-braid hose, which is more resistant to bursting and can handle tight spaces without breaking.

Secure Your Connections

Even if you’re using the right connectors, it doesn’t hurt to reinforce them. Use a wrench to keep the valve snug, but don’t over-tighten it, as too much tension can damage gaskets. Inspect your connection points to note any signs of dripping.

Level the Dishwasher

Sometimes, dishwashers leak because they’re on unstable ground. Use the adjustable feet to prevent it from tilting, and use a level tool to keep things precise. 

Check the Door Seal Alignment

During installation, ensure the door’s mounting brackets are perfectly square. Visually inspect the rubber gasket before running your dishwasher for the first time. 

Do a Test Run

Run the dishwasher on a short cycle and observe how it functions. Keep it slightly pulled out so you can check underneath for leaks. If you detect something wrong, fix it immediately before it becomes a future problem.

Replacing a Dishwasher? What to Check to Avoid a Future Denied Claim

Getting a new dishwasher is a great way to prevent future leaks and water damage. However, you still need to be proactive about installation and documentation. Here’s a handy checklist of things to keep in mind to avoid future denied claims:

A thorough inspection:

It’s best to inspect the appliance for any defects before installing it, especially if it gets damaged in transit. It’s better to replace a dishwasher early on than to discover cracks and loose ends later.

Purchase receipts and warranty info:

File away your receipts and warranty – this can be useful if your machine malfunctions prematurely. If a leak occurs and it causes damage, the insurance adjuster can use your receipts as proof of the appliance’s age and value.

Routine maintenance:

The best way to keep your dishwasher from leaking is through regular maintenance. Every few months, check the washer’s door gasket, connections, and for any cracks. 

Supervision:

Run the dishwasher only when someone is home. If something goes wrong, they can tend to any leaks before major damage occurs.

Key Advice from MyChoice

  • Always keep proper evidence of the installation and maintain your appliance to prove to your insurer that you’ve done everything possible to keep your washer in good shape. 
  • Don’t use regular dish soap, as it can create excess suds that cause your washer to overflow. Use the recommended detergent.
  • Review your policy language. Many have wear and tear and maintenance exclusions that apply to slow dishwasher leaks.

Congratulations! You made it to the end!
