The short answer
A Costway compact dryer that stops partway or restarts itself is usually protecting itself or waiting on something the owner controls: a full condensate tank, a blocked filter or an overheated cabinet. These machines have small margins, and the control stops rather than pushing through a restriction.
What you are actually seeing
- The cycle stops partway with time still showing — Means: on-page
- The machine stops and will not restart until it has cooled — Means: on-page
- The cycle restarts itself from the beginning — Means: on-page
- The machine stops at the same point every time — Means: on-page
- The timer runs down but the load is still damp — Means: on-page
- The machine never starts at all — Means: different-fault — Go to: costway-dryer-wont-start
- The cycle completes but the load is damp — Means: different-fault — Go to: costway-dryer-cleaning-performance
- Body: Match what you see before you take anything apart. The cycle stops partway with time still showing. The machine stops and will not restart until it has cooled. The cycle restarts itself from the beginning. The machine stops at the same point every time. The timer runs down but the load is still damp. Some near-miss symptoms belong on a different page: The machine never starts at all points at a supply or door fault, covered on costway-dryer-wont-start; The cycle completes but the load is damp points at a drying performance problem, covered on costway-dryer-cleaning-performance.
Causes, ranked for this machine
- A thermal cut-out opening because of a blocked filter or a restricted vent — Why this rank: First because it is the machine protecting itself and it produces exactly this pattern: a cycle that stops and will not restart until cool
- A full condensate tank stopping a ventless machine — Why this rank: The machine is doing what it was designed to do, and emptying the tank restarts it
- A door that is being nudged open, or a door switch that is marginal — Why this rank: The interlock stops the machine immediately, which owners read as a stall
- An overloaded drum, so the load never reaches a dryness the control will accept — Why this rank: On a sensor-controlled machine this produces a cycle that keeps extending or restarting
- A failed sensor, timer or control board — 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 thermal cut-out opening because of a blocked filter or a restricted vent. First because it is the machine protecting itself and it produces exactly this pattern: a cycle that stops and will not restart until cool. Next most likely: A full condensate tank stopping a ventless machine. The machine is doing what it was designed to do, and emptying the tank restarts it. Third: A door that is being nudged open, or a door switch that is marginal. The interlock stops the machine immediately, which owners read as a stall. Fourth: An overloaded drum, so the load never reaches a dryness the control will accept. On a sensor-controlled machine this produces a cycle that keeps extending or restarting. Fifth: A failed sensor, timer or control board. Last because it needs a part and everything above it is free.
What to check, in order
- Clear the lint filter and the vent, then let the machine cool before restarting
- Empty the condensate tank on a ventless machine
- Close the door firmly and run a cycle without touching it
- Halve the load and run the same cycle again
- Body: Each check rules out the causes above it. First, clear the lint filter and the vent, then let the machine cool before restarting. Second, empty the condensate tank on a ventless machine. Third, close the door firmly and run a cycle without touching it. Fourth, halve the load and run the same cycle again.
Checks you can safely make yourself
- Unplug the machine, clear the lint filter completely and straighten the vent hose, then leave the machine to cool — Tools: brush, torch — Time estimate: half an hour
- Remove and empty the condensate tank, then refit it until it seats fully — Tools: none — Time estimate: a few minutes
- Close the door firmly and run a complete short cycle without opening or nudging it — Tools: none — Time estimate: one short cycle
- Run the same cycle with half the load and note whether it now completes — Tools: none — Time estimate: one cycle
- Write down where in the cycle the machine stops and whether the cabinet is hot at that moment — Tools: notepad — Time estimate: one cycle
- Body: Checks an owner can make with the machine unplugged or by watching a short cycle. Step one: Unplug the machine, clear the lint filter completely and straighten the vent hose, then leave the machine to cool. Tools: brush, torch. Time: half an hour. Step two: Remove and empty the condensate tank, then refit it until it seats fully. Tools: none. Time: a few minutes. Step three: Close the door firmly and run a complete short cycle without opening or nudging it. Tools: none. Time: one short cycle. Step four: Run the same cycle with half the load and note whether it now completes. Tools: none. Time: one cycle. Step five: Write down where in the cycle the machine stops and whether the cabinet is hot at that moment. Tools: notepad. Time: one cycle.
Safety first
Safety
Unplug the machine before clearing a filter or a vent, and never run a heated dryer with the filter removed. Let an overheated machine cool fully before restarting it rather than repeatedly retrying. 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 filter and vent are clear, the tank is empty, the door stays closed, the load is halved and the cycle still stops at the same point. That points at a sensor, the timer or a cut-out that keeps opening.

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.
