The short answer
On a ventless Costway dryer, drainage means the condensate path: a tank you empty or a hose you position. A full tank stops the machine, and a badly routed hose will not carry water away. On a vented machine there is no drain at all, so establish which type you have before you look for one.
What you are actually seeing
- The machine stops partway with a full tank indicator — Means: on-page
- The condensate tank is full at the end of every cycle — Means: on-page
- Water is not reaching the drain hose outlet — Means: on-page
- The machine stops and restarts without completing — Means: on-page
- There is no tank and no drain hose anywhere on the machine — Means: on-page
- Water on the floor rather than in the tank — Means: different-fault — Go to: costway-dryer-water-leak
- The load is damp with an empty tank — Means: different-fault — Go to: costway-dryer-cleaning-performance
- Body: Match what you see before you take anything apart. The machine stops partway with a full tank indicator. The condensate tank is full at the end of every cycle. Water is not reaching the drain hose outlet. The machine stops and restarts without completing. There is no tank and no drain hose anywhere on the machine. Some near-miss symptoms belong on a different page: Water on the floor rather than in the tank points at a condensate overflow or leak, covered on costway-dryer-water-leak; The load is damp with an empty tank points at a drying performance problem, covered on costway-dryer-cleaning-performance.
Causes, ranked for this machine
- A condensate tank that has not been emptied — Why this rank: First because on a ventless machine the tank fills every cycle and emptying it is an owner step rather than an automatic one
- A drain hose routed upward or kinked, so water cannot flow away — Why this rank: The hose has to run downhill to its outlet, and pushing the machine back against a wall is what kinks it
- A blocked condenser or filter reducing how much water is collected at all — Why this rank: A machine that collects little water is usually not condensing properly rather than not draining
- A tank not seated properly, so the machine reads it as full — Why this rank: Free to check and easily wrong after emptying
- A failed pump or level sensor — Why this rank: Last because it needs a part and everything above it is free
- Body: Ranked for a compact or portable dryer on a household outlet: either a vented machine with a short flexible hose, or a ventless machine that collects condensate in a tank or sends it down a drain hose. Most likely: A condensate tank that has not been emptied. First because on a ventless machine the tank fills every cycle and emptying it is an owner step rather than an automatic one. Next most likely: A drain hose routed upward or kinked, so water cannot flow away. The hose has to run downhill to its outlet, and pushing the machine back against a wall is what kinks it. Third: A blocked condenser or filter reducing how much water is collected at all. A machine that collects little water is usually not condensing properly rather than not draining. Fourth: A tank not seated properly, so the machine reads it as full. Free to check and easily wrong after emptying. Fifth: A failed pump or level sensor. Last because it needs a part and everything above it is free.
What to check, in order
- Establish whether the machine is ventless with a tank, ventless on a hose, or vented with neither
- Empty the condensate tank and reseat it fully
- Route the drain hose downhill to its outlet with no kinks
- Clean the condenser and the filters
- Body: Each check rules out the causes above it. First, establish whether the machine is ventless with a tank, ventless on a hose, or vented with neither. Second, empty the condensate tank and reseat it fully. Third, route the drain hose downhill to its outlet with no kinks. Fourth, clean the condenser and the filters.
Checks you can safely make yourself
- Look over the machine for a condensate tank, a drain hose or a vent outlet, and check the rating plate for the type — Tools: torch — Time estimate: a few minutes
- Remove the condensate tank, empty it completely and refit it until it seats fully — Tools: none — Time estimate: a few minutes
- Pull the machine forward and route the drain hose downhill to its outlet, removing any rise or kink — Tools: torch — Time estimate: a quarter of an hour
- Unplug the machine, remove and clean the condenser and the secondary filter according to the markings on the machine — Tools: brush, water — Time estimate: half an hour
- Run a short cycle and check how much water reaches the tank or the outlet — Tools: none — Time estimate: one short cycle
- Body: Checks an owner can make with the machine unplugged or by watching a short cycle. Step one: Look over the machine for a condensate tank, a drain hose or a vent outlet, and check the rating plate for the type. Tools: torch. Time: a few minutes. Step two: Remove the condensate tank, empty it completely and refit it until it seats fully. Tools: none. Time: a few minutes. Step three: Pull the machine forward and route the drain hose downhill to its outlet, removing any rise or kink. Tools: torch. Time: a quarter of an hour. Step four: Unplug the machine, remove and clean the condenser and the secondary filter according to the markings on the machine. Tools: brush, water. Time: half an hour. Step five: Run a short cycle and check how much water reaches the tank or the outlet. Tools: none. Time: one short cycle.
Safety first
Safety
Unplug the machine before removing a condenser or reaching into a filter housing, and be ready for standing water. Do not run a condensing machine with the condenser removed, and dry the floor before restoring power. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. unplug-before-service
Where the owner fix ends
Call for a warranty claim or a technician when the tank is empty and seated, the hose runs downhill without a kink, the condenser and filters are clean, and the machine still stops on a full tank or collects no water. That points at the pump or the level sensor.

Generalized information
This page is generalized across the Costway compact dryer line. Vented compact tumble dryers, ventless condensing machines and spin extractors share the ranking above but almost none of their parts, and this page does not cover a specific model or control revision.
