A puddle of water forming beneath your dishwasher is never a welcome sight. Whether it’s a slow drip or a full-on flood, a leaking dishwasher can damage your floors, cabinets, and subflooring if left unaddressed. The good news? Most dishwasher leaks have identifiable causes — and many can be fixed without an expensive call-out fee.
In this guide, the Refitec team walks you through the most common reasons your dishwasher might be leaking, how to diagnose the problem, and what to do next.
1. Damaged or Worn Door Gasket
The door gasket (also called a door seal) is a rubber strip that runs around the inside edge of your dishwasher door. Its job is to create a watertight seal every time the door closes. Over time, this gasket can crack, harden, warp, or accumulate food debris — all of which prevent a proper seal.
Signs of a faulty door gasket:
- Water leaking from the front of the dishwasher
- Visible cracks, tears, or hardening on the rubber seal
- The door doesn’t feel snug when shut
What to do: Inspect the gasket by running your finger along its entire length. If it feels brittle or you can see damage, it likely needs replacing. Gasket replacements are relatively affordable and are one of the most common dishwasher repairs Refitec handles.
2. Loose or Cracked Door Latch
A door that doesn’t latch securely won’t press the gasket tightly enough against the tub, allowing water to escape during a wash cycle. The latch mechanism can wear out or become misaligned with regular use.
What to do: Check that the door closes firmly with a solid click. If it feels loose or the door moves during a cycle, the latch may need adjustment or replacement.
3. Faulty or Clogged Drain Hose
The drain hose carries wastewater out of the dishwasher and into your sink drain or garbage disposal. If this hose becomes cracked, kinked, or disconnected, water can leak beneath the appliance.
Signs of a drain hose problem:
- Water pooling directly under the dishwasher, not at the front
- Unusual gurgling sounds during the drain cycle
- Water backing up into the bottom of the dishwasher
What to do: Pull the dishwasher out slightly (after switching it off at the mains) and inspect the hose for visible damage or loose connections. A kinked hose can sometimes be straightened; a cracked one will need replacing.
4. Damaged Wash Arm or Spray Arm
Dishwashers use rotating spray arms to distribute water throughout the tub. If a spray arm becomes cracked or clogged, it can direct water in the wrong direction — including toward the door seal, increasing the chance of leaking.
What to do: Remove the spray arms and inspect them for cracks or blockages. Clean any clogged holes with a toothpick. If damaged, replacement spray arms are inexpensive and easy to fit.
5. Using the Wrong Detergent or Too Much Detergent
This is one of the most overlooked causes of dishwasher leaks. Using regular washing-up liquid, or adding too much dishwasher detergent, creates excessive suds. These suds can build up pressure inside the tub and force water out through the door seal.
What to do: Always use a detergent specifically designed for dishwashers, and follow the manufacturer’s recommended dosage. If you’ve accidentally used the wrong soap, run an empty rinse cycle a few times to clear the excess suds.
6. Worn Pump Seal or Pump Housing Leak
The pump is the heart of your dishwasher — it circulates water during washing and expels it during draining. The pump has internal seals that prevent water from escaping. Over time, these seals can degrade and allow water to drip down inside the machine.
Signs of a pump seal issue:
- Water pooling at the very bottom of the unit, unseen until it spreads
- Unusual noise during washing or draining cycles
What to do: This repair is more involved and typically requires a qualified appliance technician. If you suspect a pump issue, contact the Refitec team for a professional assessment.
7. Cracked or Loose Water Inlet Valve
The water inlet valve controls the flow of water into the dishwasher. If it becomes cracked or the connection point loosens, it can leak — usually at the back or bottom of the appliance.
What to do: This part sits behind the lower kick plate at the front of the dishwasher. If water appears to be coming from the back of the unit or you notice the dishwasher fills with water even when not in use, a faulty inlet valve could be the culprit. A technician can diagnose and replace this part safely.
8. Unlevel Dishwasher
If your dishwasher isn’t perfectly level, water can pool to one side and overflow through the door during a wash cycle. This is a surprisingly common issue that’s easy to overlook.
What to do: Use a spirit level on the base of the appliance. Most dishwashers have adjustable feet — turn them clockwise to raise the appliance, anticlockwise to lower it. Aim for a very slight rear tilt to encourage drainage toward the back.
When to Call a Professional
While some dishwasher leaks are DIY-friendly (like replacing a gasket or clearing a clogged spray arm), others involve internal components that require the right tools and expertise. If you’re unsure of the source of the leak, or if the problem involves the pump, motor, or inlet valve, it’s always safer — and often more cost-effective — to call in a professional.
