What S1 means on your Asko dryer (asko dryer s1 td70.3)
An asko dryer s1 td70.3 problem carries the identical overflow meaning as S1 on the TD70.2 board it follows: the condensate tank is full and needs to be emptied before the cycle can continue. TD70.3 is the fourth board revision in this platform’s history, and it is notable for keeping S1 unchanged from TD70.2 while renaming the two codes around it — the time-limit problem becomes J1 instead of S2, and the thermistor failure becomes LCD1 instead of S3. TD70.3 also introduces two entirely new maintenance prompts, LCD2 and LCD3, that neither the TD70.1 nor TD70.2 panels display at all. If your unit is on this newer board, the tank-full alert behaves and clears exactly the same way as it does on a TD70.2 machine.
Symptoms
Line the points below up against your Asko dryer to be confident this is the problem you are dealing with and not a similar one. A dryer can display a single symptom or several at once, whether they build slowly or appear abruptly after a surge, a spill, or recent installation and testing.
- The display shows S1 and the cycle pauses or stops
- The condensate tank feels heavy or is visibly full when pulled out
- The dryer resumes as soon as the tank is emptied and reseated
- S1 recurs at a similar point in the cycle for consistently large loads
Common causes
The same symptoms on an Asko dryer point to several possible problems, so the causes here start with the most common. Ruling each out in turn shows whether your dryer has a quick fix or a problem that needs proper diagnosis and the right parts.
- Condensate tank genuinely full — normal result of drying, especially with larger loads
- Tank not fully seated — an incompletely inserted tank can leave the switch reading open
- Worn microswitch — contact wear or residue can cause a false full reading
- Blocked drain hose — on units plumbed to a direct drain, a kink or clog can stop the tank from clearing on its own
Troubleshooting steps you can try
Go through the steps on your Asko dryer from top to bottom before booking a repair, since the early ones cover the common causes. The moment mains voltage, gas, a hot cavity, water, or a sealed component enters the picture on the dryer, hand the job to a qualified technician.
- Remove the condensate tank and empty it fully.
- Clean the tank and the cabinet opening before reinserting.
- Push the tank all the way home until it seats and clicks.
- Restart the program and confirm S1 clears.
- Check any connected drain hose for kinks if S1 keeps returning with an empty, correctly seated tank.
Parts a technician may replace
Diagnosis on your Asko dryer may lead a technician to inspect, test, or replace the condensate tank, tank microswitch, and drain hose (where fitted). The failed part is confirmed on the dryer before anything is ordered, and only genuine OEM or trusted-supplier parts — matched by model, serial, and Art. No. — go back into the machine.
When to call a technician
S1 that returns right after a correctly reseated, empty tank needs an experienced technician to test the tank microswitch on your TD70.3 dryer. Rated Low severity, this condition does not put your Asko dryer at immediate risk; still, if S1 persists on the dryer after you have worked through the steps, let a technician pin down the cause before replacing anything. Repairs to your Asko dryer are carried out independently, with no tie to Asko, Gorenje, or Hisense; we use experienced technicians and genuine OEM or trusted-supplier parts, and stand behind the labor on your dryer for 30 days. Have your Asko dryer’s rating-plate details — model, serial, and Art. No. — ready at booking so the exact part for the dryer is sourced in advance and S1 is cleared efficiently.
