Heat-Pump Dryer Leaking Water Onto the Floor?

Why is my heat-pump dryer leaking water onto the floor?#

The most likely reason a heat-pump dryer leaks is an overfull or cracked condensate tank, since the machine collects the water it pulls from your clothes and stores it in that tank until you empty it. If the tank overflows, cracks, or seats badly, that water ends up on the floor. The table below lists the other causes — a blocked or kinked drain hose on models plumbed to a drain, a failing condensate pump or its hose, and an overflowing internal sump. The tell-tale is a puddle under the front of the machine, usually near the base or the tank drawer, rather than water spreading from a supply line, because a dryer has no incoming water supply to leak.

Leaking water onto the floor: likely causes, ranked#

The heat pump collects the water it condenses, so a leak points to the tank, the drain path, or a seal — not a plumbing supply. You will find a puddle under the front of the machine, usually near the base or the tank drawer.

Safe checks to try first#

Because the leak is the dryer's own collected water, trace it from the tank outward. First, pull the condensate tank, empty it, and check it for cracks or a warped lid, then reseat it firmly — a tank that is overfull, damaged, or not clicked home is the most common source of a floor puddle. Second, look at the fluff filters and the condenser: a fouled condenser can make the machine mishandle condensate and overfill, so clear the filters and clean the heat exchanger per your model. Third, if your dryer is plumbed to a drain instead of using the tank, check that the drain hose is not blocked or kinked and sits correctly. Reserve the cycle check for context — a very wet, heavy load produces the most condensate and can expose a marginal tank or pump. If water still appears after the tank, filters, condenser, and drain hose are all checked and sound, stop and book a technician, because the leak is then coming from the pump or an internal sump you cannot reach.

When to call a technician#

The owner side is the tank, the filters, the condenser, and — on plumbed models — the drain hose, all of which you can inspect and correct. What needs a technician is a leak that continues once those are ruled out, because it points inside the machine: a failing condensate pump or a split internal hose, or an internal sump overflowing because it is not being emptied by the pump. Those are sealed away and require the machine to be opened. A puddle that returns after you have emptied and reseated a sound tank and cleared the drain path is the signal that the fault is internal, and chasing it further at home risks water on electrical parts, so it is a technician's repair from that point.

Common questions#

Why is my heat-pump dryer leaking water onto the floor?#

Most often the condensate tank is overfull, cracked, or seated poorly, so the water the dryer collects escapes. A blocked drain hose, a failing condensate pump, or an overflowing internal sump can also be behind it. Since the dryer has no water supply, the leak is always its own collected condensate.

Could an overfull or cracked condensate tank be the cause?#

Yes, this is the leading cause. The tank holds the water pulled from your laundry, and if it overfills between empties, cracks, or does not seat properly, that water runs onto the floor. Empty it, check it for damage, and click it firmly back in — that alone resolves many leaks.

Does a blocked or kinked drain hose explain it?#

On models plumbed to a drain, yes. If you have routed the dryer's condensate to a drain instead of the tank, a blocked or kinked hose backs the water up until it escapes. Check the hose runs freely without kinks and is seated correctly at both ends before looking deeper.

Should I check a failing condensate pump or hose first?#

Check the tank and drain path first, because those are the accessible causes. A failing pump or a split internal hose is inside the machine, so it comes after you have ruled out an overfull tank and a blocked drain. If the leak persists once those are sound, the pump or an internal hose is the likely culprit and needs a technician.

Can an overflowing internal sump do this?#

Yes. Water collects in an internal sump before the pump moves it to the tank or drain, and if the pump underperforms or the sump path clogs, that sump can overflow inside the cabinet and leak out. This is internal to the machine and is a technician's diagnosis rather than an owner check.

Is this a DIY fix or a technician job?#

It often starts as a do-it-yourself fix: empty and inspect the tank, clear the filters and condenser, and check the drain hose on plumbed models. If water keeps appearing after all of that, the leak is from the pump or an internal sump, and that is when to call a technician rather than continue chasing it.
