Why Is My Dishwasher Leaking?
Dishwashers use a sealed wash system, so any leak indicates that a seal, hose, or component has failed. Leaks can appear at the front door, underneath the unit, or from the rear connections. Identifying where the water appears helps narrow the cause.
Quick DIY Checks Before You Call
Before booking a technician, try these quick checks:
- Check the door seal for debris — Food scraps, grease, or small items (like broken glass) can get caught in the rubber door gasket, preventing a proper seal. Wipe the gasket clean with a damp cloth and inspect for visible food buildup along the entire seal.
- Check spray arms for cracks — Remove the lower and upper spray arms (they usually twist off). Inspect them for cracks, splits, or holes. A cracked spray arm can shoot water directly at the door seal, causing leaks during the wash cycle.
- Don’t use regular dishwashing liquid — Using hand dishwashing liquid (like Morning Fresh) instead of dishwasher detergent creates excessive suds that overflow through the door seal. If you see suds leaking out, run an empty cycle to flush the system.
- Check the dishwasher is level — A dishwasher that’s tilted forward can cause water to pool at the front and leak out the door. Place a spirit level on the open door and adjust the feet if needed.
Common Causes We Repair
When DIY checks don’t solve the leak, these are the faults our technicians find most often:
Worn Door Gasket
The rubber gasket around the dishwasher door perishes over time — it becomes hard, cracked, or compressed and no longer creates a watertight seal. You’ll notice water leaking from the front corners of the door during the wash cycle. Gasket replacement is a straightforward repair we complete on-site for all major brands.
Cracked Sump or Wash Chamber
The sump (base of the wash chamber) collects water between cycles. Cracks from thermal stress, accidental impact, or age allow water to seep out underneath the dishwasher. This type of leak is often slow and persistent — you might notice water even when the dishwasher isn’t running if residual water is draining through the crack.
Failed Water Inlet Valve
The inlet valve controls water flow into the dishwasher. When it fails, it can either leak from its housing or fail to close properly — allowing water to continuously trickle into the machine even when it’s off. If your dishwasher is overflowing or you notice water in it between cycles, the inlet valve is a likely suspect.
Loose or Damaged Hose Clamps
Internal hoses connect the pump, sump, and drain. Over time, hose clamps can loosen or the hoses themselves can split — especially near heat sources like the heating element. Leaks from hose connections often appear underneath the dishwasher and only occur during certain cycle stages (filling, washing, or draining).

Frequently Asked Questions
Is a leaking dishwasher dangerous?
A leaking dishwasher can cause water damage to flooring and cabinetry, promote mould growth, and potentially create an electrical hazard if water reaches electrical components. It’s best to stop using the dishwasher until the leak is repaired.
Why does my dishwasher only leak during certain cycles?
Different cycle stages use different water levels and pressures. A leak that only appears during the wash (high pressure spray) points to door seal or spray arm issues. A leak during filling suggests an inlet valve problem. A leak during draining points to pump seals or drain hose issues.
Can I still use my dishwasher if it’s leaking?
We recommend stopping use until the leak is diagnosed. Continued use can worsen water damage to your kitchen, and if the leak is from an electrical component, it could become a safety hazard. Hand wash dishes until your repair appointment.
How do I find where my dishwasher is leaking from?
Place newspaper or paper towels under and around the dishwasher, then run a short cycle. The wet spots will show you where water is escaping. Front door leaks leave water on the floor in front; underneath leaks tend to pool beneath the machine. This information helps our technician diagnose the issue faster.
