A standard vented dryer has no water supply, no drain and no pump, so a dryer leaking water is usually not leaking at all — the water came from somewhere else and arrived underneath it. Three sources cover nearly all of it: the washer beside it, condensation in a restricted exhaust duct, or a condensing model whose tank, hose or sump has stopped clearing. A fourth applies only to a steam dryer, which really is plumbed to a tap.
So the first job is not diagnosis. It is finding where the floor is wettest.
A vented dryer has no water in it
This is the reframe the ranking pages skip, and it is the difference between this page and a washer leak. A vented dryer’s entire relationship with water is that it removes it: room air in, past a heater, moisture picked up from the load, out through the duct. No inlet valve to weep, no bellows to split, no drain pump to crack — the parts behind a washing machine leaking water are not fitted. So the question inverts: which other appliance is contributing it? Two machines, one tap.
Unless it is a steam dryer, which is plumbed to a tap
Steam models are the exception, and plenty of owners do not know they have one. These carry an inlet hose and an inlet valve, so the washer-style failure set applies. Whirlpool’s timing detail explains why people miss it: “During the Steam cycles, water is sprayed at about 4-5 minutes into the cycle for about 5 minutes. The spray may not be visible” (Whirlpool — Leaking During Steam Cycle). Water that starts five minutes in and stops at ten points at that connection, and the checks are ordinary plumbing: hose tight at both ends, washers present.
A dryer leaking water from the bottom: the condensing models
Ventless machines really do hold water, because that is how they work — moisture is condensed out of recirculated air and has to go somewhere. A drain hose carries it off, or a removable tank collects it, and Whirlpool’s instruction is titled exactly that: “Emptying the Water Tank (if the drain hose is not connected to another drain system).” Miss a few loads and it overflows, which looks like a fault.
When it is the hose, Whirlpool supplies numbers (Whirlpool — Water on Floor, HybridCare Dryer). The dryer “needs to have a slope less than 1″ (25 mm)”, and the hose “can be installed no higher than 72″(1.8 m) from bottom of the dryer”. Then a cause nobody guesses: “Water could accumulate on the floor if the HybridCare™ filter is not properly seated.”
LG files the same failure as a code, and the last word of its definition earns its place in winter: E13 “indicates that the drain hose is kinked, crushed, clogged or that the water in the sump is frozen” (LG). A garage dryer in January is a different machine from the same model indoors (how does a heat pump dryer work).
Duct condensation, and the weather that starts it
A vented dryer can put water on the floor without holding any. Hot saturated air cooling inside a long, cold or restricted duct drops its moisture as liquid, which runs back to the lowest point — the joint behind the machine. Whirlpool: “If the vent is restricted condensation could build up in the dryer.” Two things start this where nothing else changed: cold weather, since a duct crossing an unheated loft cools the air far faster, and lint, which narrows the duct and holds moisture against the metal. The fix is the duct (how to clean a dryer vent).
Observations that end the guessing
- Water appears only during a steam cycle, about five minutes in. The inlet hose or valve.
- Wet at the duct joint behind the machine, not under the cabinet. Condensation.
- A ventless model’s tank is full, or its hose runs above 72 inches. Whirlpool’s limit, exceeded.
- Any water near a cord, outlet or plug. Off at the breaker before you mop.
FAQ
Can a vented dryer leak water?
Not in the plumbing sense — no supply, no drain, no pump. It can deposit condensation formed in a cold or restricted duct, which runs back to the joint behind it.
Why is there water inside my dryer drum?
On a steam model, Whirlpool documents steam condensing on the door and dripping when it opens, especially with small loads. On a ventless model, check the tank.
How high can a condensing dryer’s drain hose go?
Whirlpool’s figure is explicit: no higher than 72 inches (1.8 m) from the bottom of the dryer. Above that the water cannot clear.
Can freezing weather make a dryer leak?
Yes, on a ventless model. LG’s E13 definition includes “the water in the sump is frozen”, so a dryer in an unheated garage has a failure mode the indoor one lacks.
Trace the water, then name the appliance
Put a dry towel under each machine and run one load at a time. It tells you which appliance is producing water — the question people skip on the way to buying the wrong part.
If the dryer is vented and its towel stays dry while the washer’s soaks, nothing is wrong with the dryer. If it is a condensing model, empty the tank and straighten the hose first.
