Common causes of dishwasher leaking water
Door Seal Issues
minorCan DIY checkThe rubber gasket around the dishwasher door can become dirty, torn, or brittle, preventing a watertight seal. This allows water to escape during the wash cycle.
Improper Loading
minorCan DIY checkOverfilling the dishwasher or placing large items in a way that obstructs the spray arm can cause water to splash out or prevent the door from sealing correctly.
Clogged Drain Filter or Hose
importantCan DIY checkA blocked filter or drain hose prevents water from draining properly, leading to excess water backing up and potentially leaking from the unit.
Cracked Tub or Component
criticalPro recommendedOver time, the plastic or metal tub, or internal components like the pump housing, can develop cracks, allowing water to seep out.
Loose Hose Connections
importantPro recommendedWater supply or drain hoses can become loose over time, especially at the connection points to the dishwasher or the plumbing, causing leaks.
Faulty Water Inlet Valve
criticalPro recommendedIf the valve that controls water entering the dishwasher is stuck open or damaged, it can overfill the tub, leading to leaks.
Quick checks you can run safely
- 1
Check for Obstructions and Proper Loading
Ensure no large dishes are blocking the door from closing fully or preventing the spray arm from rotating freely. Make sure the dishwasher isn't overloaded.
Safety: Be careful of sharp edges on dishes. - 2
Inspect the Door Seal
Carefully examine the rubber gasket around the door for any tears, cracks, or hardened areas. Clean the seal and the door edge where it makes contact.
Safety: The dishwasher interior and door edges may have sharp metal components. - 3
Check the Drain Filter
Locate and remove the filter, usually at the bottom of the tub. Clean out any food debris or foreign objects. Reinstall it securely.
Safety: Ensure the dishwasher is unplugged before reaching into the tub. - 4
Examine the Exterior for Obvious Leaks
Look under and around the dishwasher for visible signs of water. Check the connections for the water supply line and drain hose.
Safety: The area around the dishwasher may be wet and slippery. Ensure the dishwasher is unplugged before attempting to move it or inspect connections closely.
When to call a pro right away
Water is leaking rapidly or continuously
A significant leak can cause extensive water damage to floors, cabinets, and subflooring. It may indicate a major component failure.
You suspect a leak from internal components or hoses
Accessing internal parts requires disassembly and can involve electrical components or water lines. Incorrect reassembly can worsen leaks or cause other problems.
Water is leaking near the electrical connections or control panel
Water and electricity are a dangerous combination. This situation poses an immediate electrocution risk.
The dishwasher is making unusual noises along with the leak
This could indicate a failing pump or motor, which requires professional diagnosis and repair.

How our repair process works
Five steps from your first call to the warranty receipt. No surprises.
- 1
Inspection
Your technician examines the appliance, listens to your description, and notes the model + serial for parts lookup. Visual + audio-based diagnostics first — non-invasive.
- 2
Diagnostics
Targeted tests on the failing subsystem (compressor, control board, heating element, motor, etc.) to identify the exact root cause. You get a clear explanation, not jargon.
- 3
Fix decision
Up-front estimate before any work begins: cost, parts, and the realistic likelihood of success vs. recommending replacement on an old or uneconomical unit. You decide.
- 4
Operational test
After the repair we run the appliance through its normal cycle on-site — never "it should work now, call us if it doesn't." You sign off when it's actually working.
- 5
Warranty + consultation
Receipt with warranty terms in writing. Plus a quick walkthrough of how to extend the appliance's life (filter cleaning, drain maintenance, etc.) — included free.
