The short answer
Leaks on the Costway EP dishwasher family sort themselves by timing as much as by position: a leak during the fill points at the supply side, a leak throughout the wash points at the door or the sump, and a puddle that appears hours later points at a slow connection rather than a cycle fault.
What you see on the EP family
- Water on the floor directly in front of the door — The classic door-seal or levelling pattern. It arrives during the wash rather than at the fill.
- Foam pushing out around the door — Over-sudsing, almost always from hand dish soap or too much detergent in soft water. The machine is fine; the chemistry is not.
- A puddle under the machine with a dry door — Supply side or sump. It means pulling the toe kick to see where it originates, which is where the owner checks end.
- Water appears only on the heavy or hot cycles — Heat expands gaskets and raises pressure. A seal that only leaks hot is still a failing seal.
Causes, most likely first on the EP family
- Door gasket and door alignment — Ranked first on the EP family — it is the most common leak on any dishwasher and on this model it is inspectable in seconds with the door open. The gasket hardens and takes a set, and the door drops slightly on its hinges over the years. Either one lets a thin sheet of water past at the bottom corners while the machine sprays.
- Over-sudsing from the wrong detergent — Second — and free to rule out: run one empty cycle with no detergent and see whether the leak repeats. Hand dish soap in the dispenser produces foam the machine cannot contain, and it pushes past the door seal as if the seal had failed. Excess automatic detergent in soft water does the same thing more slowly.
- Fill valve, inlet connection or hose — Third — it explains a wet cabinet with a dry door better than anything else on the list. The supply connection lives in the cabinet under the sink and the valve sits at the front of the machine behind the toe kick. A weeping compression fitting drips slowly and constantly rather than in step with the cycle.
- Sump gasket, pump seal or a cracked hose — Fourth — and the only group on this list that is not an owner repair on this model. The sump assembly seals to the tub with a gasket that ages, and the internal hoses are clamped. A leak here appears under the middle of the machine and only while it is running.
- Body: The order below is this family's rather than the brand's: with one build in the EP family the ranking is not an average diluted by chassis that fail differently, so the cause at the top is the cause that actually leads on EP24717US.
Check in this order, and why
- 1. Dry the floor completely and note where the water returns — Front of the door, under the middle, or in the sink cabinet. This one observation removes most of the list.
- 2. Inspect the gasket all the way round with the door open — Look for hardening, tears and a flattened lower corner. Wipe it and the sealing face while you are there.
- 3. Run one cycle with no detergent at all — If the leak disappears, it was suds. This is the cheapest test on the page and it is decisive.
- Body: Because the EP family is one model, the access route below is the access route — there is no second layout to hedge against, which is exactly what the page above this one has to do.
Before you open anything
Safety
Kill the breaker and close the supply valve before opening anything, and dry the floor before you work on it. A standard US household branch circuit is 15 A or 20 A at 120 V, and a wet floor removes whatever margin you had. If water has reached the cabinet floor under the machine, leave it off until the source is found rather than running another cycle to see.

When to call a technician
On the Costway EP dishwasher family the owner line is the door and the sink cabinet. Gasket, alignment, levelling, detergent and the visible supply fitting are all yours. Anything that needs the toe kick off is not, and a machine leaking onto a live connection should be switched off at the breaker and left off.
