The short answer
On the Costway FPI washer family a leak is most often a hose connection or over-sudsing rather than a failed seal, and where the water lands tells you which. The brand-generic article treats leaks as one subject; splitting them by position and by timing is what makes this page quick to use on this model.
What you see on the FPI family
- Water on the floor behind the machine — Supply hoses, their washers, or the drain hose connection. It is the most common place for washer water to appear.
- Water at the front of the machine during the wash — The door or lid seal, or foam escaping past it, rather than a plumbing connection.
- Foam pushing out of the dispenser or the door — Over-sudsing, usually too much detergent or the wrong type for the machine. The machine is fine and the chemistry is not.
- Water appears only during the drain step — The pump housing, its clamp or the drain hose connection, all of which are pressurised only at that moment.
Causes, most likely first on the FPI family
- Fill hoses, washers and their connections — Ranked first on the FPI family — water at the back on the Costway FPI washer family is this until proven otherwise, and it is visible once the machine is pulled out. Rubber fill hoses age, their washers flatten, and the connections loosen with vibration. The result is a slow weep at the back that grows between uses rather than during them.
- Over-sudsing from too much or the wrong detergent — Second — and free to rule out: run one cycle with no detergent and see whether the leak repeats. Excess foam finds every route out of the tub, including the dispenser and the door seal. It looks exactly like a failed seal and it is not a fault at all.
- Door or lid seal hardened, torn or fouled — Third — visible, cleanable and replaceable, and the usual answer when the water is at the front. A seal that has taken a set no longer conforms to the glass or the rim, and grit or a bra hook trapped in the fold holds it open at one point. Water then escapes at exactly that point every cycle.
- Pump housing, internal hose clamps or the tub seal — Fourth — and the only group on this page that is not owner work on this model. The internal hoses are clamped rather than threaded and a clamp that has relaxed leaks only when that hose is pressurised. A tub seal failure appears under the machine during the spin and is the serious end of the list.
- Body: The order below is this family's rather than the brand's: with one build in the FPI 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 FPI1218US-WH.
Check in this order, and why
- 1. Dry the floor completely and note where the water returns — Front, back, or under the middle. That single observation removes most of the candidate list.
- 2. Run one cycle with no detergent at all — If the leak disappears, it was suds. This is the cheapest decisive test on the page.
- 3. Inspect the door or lid seal all the way round — Wipe the fold clean and look for grit, tears and hardening. A bra hook in the fold is an ordinary finding.
- Body: Because the FPI 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
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Shut both taps before touching any hose or fitting. A standard US household branch circuit is 15 A or 20 A at 120 V and the floor is wet, so isolate before kneeling down rather than after.

When to call a technician
On the Costway FPI washer family the owner line is the hoses, the detergent and the seal. Those three account for most washer leaks and need no visit. Internal clamps, the pump housing and the tub seal are service work, and a machine leaking onto a live connection should be switched off at the breaker.
