Lucy Crawford Key Takeaways
- A clogged lint filter or blocked exhaust duct is the leading cause of no-heat on T600 and T700 models.
- Error code E1 signals a thermal limiter trip — often caused by restricted airflow.
- Heating element failure (error E3) is a straightforward parts swap starting from $110.
- Heat pump dryers in the T700 series show F5 for refrigerant circuit issues — always requires a technician.
- Clean the lint filter after every load to prevent thermal limiter trips.
The Bottom Line
A blocked lint path causes the majority of Asko dryer no-heat complaints and is free to fix. When error codes E1 or E3 persist after clearing the lint system, heating element or thermal limiter replacement starts from $110.
Asko dryer not heating — this comprehensive guide covers everything you need to know.
Asko T600 and T700 series dryers use precision heat management to protect fabrics, so when the drum spins but no heat is produced, the machine has almost certainly tripped a safety limiter or lost a heating component. Most causes are identifiable within minutes.
Quick Diagnosis Table
| Symptom | Error Code | Likely Cause | DIY Fix? |
|---|---|---|---|
| Drum spins, no heat produced | E1 | Thermal limiter tripped | Sometimes — clear lint first |
| Clothes damp after full cycle | None | Clogged lint filter or duct | Yes — clean filter and duct |
| Heating element fault | E3 | Failed heating element | No — element replacement |
| Heat pump error | F5 | Refrigerant or compressor issue | No — technician required |
| Overheating then shutdown | None | Blocked exhaust vent | Yes — clear exterior vent |
Step 1 — Clean the Lint Filter and Exhaust Path
Remove and clean the lint filter — on T600 models it sits inside the door opening. Then go outside and check the exhaust vent cap; a partially blocked cap reduces airflow enough to trip the thermal limiter within a single cycle. Use a dryer vent brush to clear the full duct run if it hasn't been done in the past year.
Step 2 — Reset the Thermal Limiter
After clearing the lint path, unplug the dryer for 10 minutes to allow the thermal limiter to reset passively. If error code E1 returns on the next cycle, the limiter has failed open and must be replaced — it cannot be safely reset by bypassing it. Replacement starts from $110 including labor.
Step 3 — Test the Heating Element
Error code E3 on T600 series points to a broken heating element coil. A technician will use a multimeter to confirm continuity loss across the element terminals before ordering the part. Element replacement on Asko dryers is a panel-access job typically completed within one hour.
Heat Pump Models (T700 Series)
T700 heat pump dryers do not use a conventional heating element. Error code F5 indicates a fault in the refrigerant circuit or compressor. This repair requires a certified technician with refrigerant handling credentials and is not a DIY task. Average repair cost starts from $180 for T700 heat pump faults.
Prevention Tips
Clean the lint filter after every single load — this is the single most effective maintenance step. Have the full exhaust duct professionally cleaned once a year if the run is over 3 meters or has multiple bends.

Frequently Asked Questions About Asko Dryer Not Heating
When your Asko dryer not heating problem appears on a heat pump model like the T700 series, the most likely cause is a clogged condenser. Asko heat pump dryers require condenser cleaning every 3-6 months. Remove the condenser filter panel and rinse under running water until clear.
If your Asko dryer not heating issue started gradually, the heat pump refrigerant charge may be low due to a slow leak. Unlike conventional dryers, Asko heat pump models use a sealed refrigerant circuit similar to a small air conditioner. This repair requires a certified refrigeration technician.
The Asko dryer not heating problem on conventional T600 models usually points to a failed heating element or thermal fuse. Check continuity across both components with a multimeter. The thermal fuse is a safety device that blows permanently when the dryer overheats due to restricted airflow.
