Why Is My Dishwasher Leaking Water?
A leaking dishwasher can be caused by a damaged door seal, split hose, loose clamp, cracked spray arm, overfilling, blocked filter area, or water escaping from the sump or pump housing. The first step is to identify where the water is coming from.

At a Glance
- Door-area leaks often point to seals, spray issues, loading problems, or detergent oversudsing.
- Leaks underneath the appliance are more likely to involve hoses, pump housings, or sump components.
- Estimated time: 15-60 minutes depending on the source.
Safety First
Disconnect power and turn off the water supply before inspecting hoses, base panels, or the sump area.
Common Causes
- Worn or distorted door seal
- Spray arm split or blocked, directing water wrongly
- Overfilling due to valve or level fault
- Loose inlet or drain hose connection
- Cracked sump, pump housing, or internal hose
- Poor loading causing spray deflection at the door
Quick Checks First
- Check whether the water appears at the front, rear, or underneath.
- Inspect the door seal for flattening, splits, or debris.
- Check the spray arms for cracks and free rotation.
- Make sure tall items are not preventing the door closing properly or deflecting spray.
- Inspect visible hoses and clamps for drips or mineral traces.
