Water on the floor after a dishwasher cycle usually traces to one of a few spots, and finding where it leaks tells you what to fix. A surprising number of "leaks" are actually the wrong detergent making suds overflow. Here's how we track it down, easiest first.
Regular dish soap, or way too much detergent, creates suds that push out past the door seal and onto the floor. It looks like a leak but the machine is fine.
Check it: Only ever use automatic-dishwasher detergent, in the right amount. If someone used hand-dish soap, run rinse-only cycles to clear the suds.
The rubber seal around the door hardens, tears, or gets crusted with food so water escapes at the door — usually you'll see it dripping from the bottom of the door.
Check it: Wipe the door gasket clean and inspect it for cracks, gaps, or a permanent set. A replacement gasket is a cheap, common part.
The drain hose connection under the sink (at the disposal or air gap) can loosen or clog and leak during the drain step.
Check it: Check under the sink during a cycle — look for drips at the hose clamps and the disposal/air-gap connection. Snug a loose clamp; a cracked hose needs replacing.
The valve that fills the dishwasher can leak or fail to shut off, letting water seep out the bottom.
Check it: Water present even when the dishwasher is off points at the inlet valve. Replacement is a technician repair.
A door that doesn't seat squarely — from a worn latch or a machine that's not level — leaks at the corners.
Check it: Make sure the door latches firmly and the dishwasher sits level. A worn latch is an affordable part.
An older dishwasher can crack at the tub or sump and leak from underneath.
Check it: Not a DIY diagnosis. If the leak is from the base with no hose or door cause, a technician confirms whether it's worth repairing.
Most dishwasher leaks are cheap: the right detergent, a gasket, a hose clamp, or a latch. Even an inlet valve is affordable. The only time replacement makes sense is a cracked tub on an older machine — and we'll give you the honest math before you spend on it.
Last week a customer kept their appliance instead of replacing it — they installed the part themselves with the exact one we shipped, after a $50 Quick Check told them precisely what they needed. That's the whole idea: honest answer, right part, no upsell.

Find where it leaks and you'll know the cause. The most common are the wrong detergent making suds overflow (not a real leak), a worn door gasket dripping at the bottom of the door, or a loose drain-hose connection under the sink.
Intermittent leaks often mean suds from too much or the wrong detergent, or a connection that only drips during the drain step. Switch to the correct amount of dishwasher detergent and watch the under-sink hose connections during a cycle.
Often the easy causes yes — using the right detergent, cleaning or replacing the door gasket, and tightening a loose drain-hose clamp are all doable. A leaking inlet valve or a cracked tub is a technician repair.
