What S3 means on your Asko dryer (asko dryer s3)
An asko dryer s3 problem on the TD70.2 panel flags a thermistor failure — an open circuit or other malfunction in the sensor the control relies on to track drying temperature through the cycle. Unlike S1 and S2, which describe the tank and the time limit, S3 is a genuine component-level problem rather than a normal-operation status message, and it is not a code an owner can clear by emptying or resetting anything. Because the thermistor feeds the temperature data the control uses to decide when a load is dry, a faulty reading can also make loads come out under-dried or over-dried even before S3 is displayed outright.
Symptoms
The indicators below help confirm the problem on your Asko dryer instead of a different issue that mimics it. Your dryer might produce one symptom or a handful at once, whether they develop slowly or appear all at once after a power event, a demanding wash or cook, or recent installation.
- The display shows S3 and the cycle stops
- Recent loads may have come out unusually under-dried or over-dried before S3 appeared
- The dryer may refuse to start a new cycle while S3 is showing
- S3 does not clear itself after a simple restart
Common causes
A single set of symptoms on your Asko dryer can come from any of the causes below, listed with the common ones first. Eliminating them methodically separates the quick checks anyone can make on a dryer from the problems that need trained diagnosis and Asko parts.
- Open circuit in the thermistor — the sensor element itself has failed internally
- Damaged or corroded wiring to the sensor — a broken or oxidized connection interrupts the signal path
- Loose connector at the thermistor or control board — vibration over time can work a plug partway out
- Control board failure reading the sensor input — less common, but a board-side failure can also produce this reading
Troubleshooting steps you can try
Before calling anyone out, run through these checks on your Asko dryer in sequence, as a fair number of problems clear at this stage. Draw the line wherever you feel out of your depth on the dryer, or where mains power, gas, heat, water, or a sealed component comes into play, and let a technician finish.
- Power the dryer off at the outlet for a minute, then restart it to rule out a one-off glitch.
- Avoid running further cycles while S3 is displayed, since drying temperature is no longer being reliably measured.
- Check that nothing has been recently moved or serviced near the back panel that could have loosened a connector.
- If S3 returns after a restart, do not keep retrying — book service.
Parts a technician may replace
Where the problem on your Asko dryer traces to hardware, a technician inspects, tests, or replaces the thermistor (drying temperature sensor), wiring harness, and control board first. Each is matched to your dryer by model, serial, and Art. No., and genuine OEM or trusted-supplier components are used so the dryer performs as it should.
When to call a technician
S3 is a sensor-circuit failure, not an owner-serviceable condition — an experienced technician needs to test the thermistor and its wiring with a multimeter on your TD70.2 dryer. Because the severity is Medium, you can take your time with your Asko dryer; if S3 returns on the dryer after these steps, though, have a technician verify the cause rather than guessing at parts. As an independent repair service, we are not affiliated with Asko, Gorenje, or Hisense; your dryer is looked after by experienced technicians using genuine OEM or trusted-supplier parts, with a 30-day labor warranty on the work we do. When you schedule service for your Asko dryer, quote its model, serial, and Art. No. — that way the correct part is matched to the dryer beforehand and S3 is put right in as few visits as possible.
