Asko Dryer E2 Error: Overheating trip
Asko dryer E2 error is a common issue reported by Asko appliance owners. What Asko Dryer Error Code E2 Means Error code E2 on Asko dryers signals that the machine has exceeded its safe operating temperature. A thermal safety thermostat inside the heater housing has tripped, cutting power to the heater to prevent drum damage […]

Answer to continue safely
Is it safe to keep using?
No. E2 is a high-severity overheating fault. Do not restart the dryer until the cause (blocked lint path, failed thermostat) is identified and resolved. Operating an overheating dryer is a fire hazard.
Can I reset the code?
Yes. The thermal thermostat resets automatically once the machine cools. However, if the root cause (lint blockage, thermostat fault) is not fixed, E2 will recur within the next cycle.
When to stop immediately?
Stop if you notice: Any smoke or visible flame near the exhaust outlet — evacuate and call emergency services., The dryer chassis or exhaust duct is too hot to touch after a 30-minute cool-down..
Symptoms You May Notice
Drum interior and exhaust feel extremely hot
After the E2 trip the drum housing, exhaust outlet at the rear, and any accessible ductwork feel noticeably hotter than during a normal cycle end — significantly above the usual 60–70 °C operating range.
Cycle aborts before completion with no heat in remaining time
The dryer stops mid-cycle, the heater goes off, but the drum and fan may continue running in a cool-down phase before E2 is displayed.
Burning or scorched fabric smell from exhaust
A smell of overheated lint or slightly scorched fabric emanates from the exhaust vent — a warning sign that temperatures have reached a level capable of damaging laundry.
E2 recurs quickly after reset, especially on long or high-temperature programmes
The fault re-triggers within 15–20 minutes of restarting on a cotton or high-temperature programme, confirming that the root overheating condition has not been resolved.
Possible Causes
Blocked lint filter or clogged exhaust duct
A heavily clogged lint filter or blocked exhaust duct (on vented models) severely restricts hot air from escaping, causing it to recirculate and rapidly overheat the drum interior.
DIY PossibleBlocked condenser unit (condenser/heat-pump models)
On Asko T608 and DC7 heat-pump and condenser dryers, a condenser unit that has not been cleaned for several months becomes blocked with lint, trapping heat inside the machine.
DIY PossibleFaulty heater thermostat — tripping at too-low temperature
A thermostat that has drifted out of specification may trip at a temperature that is within normal operating range, causing false E2 codes. Conversely, a failed-closed thermostat can allow genuine overheating.
Requires ProfessionalSafe Checks You Can Do
-
1
Allow the dryer to cool completely before doing anything
Leave the dryer door open and the machine switched off at the mains for at least 30 minutes before touching any internal components or attempting to restart. Handling a hot dryer drum or heater assembly carries a burn risk.
Do not restart the dryer immediately after an E2 trip — the thermal thermostat needs to cool before it will reset, and restarting too soon often produces another immediate E2.

Clean lint filter, condenser, and exhaust duct
Remove and wash the lint filter under the tap. On condenser and heat-pump Asko models, open the lower access panel and clean the condenser thoroughly with a soft brush and running water. On vented models, disconnect the exhaust hose and check the full length for lint build-up and kinks. A blocked exhaust is the single most common cause of E2.
The exhaust duct on vented Asko dryers should be checked every 6 months. A flexible aluminium duct that has been crushed or kinked against the wall is particularly prone to blockage.

3
Reset and run a short low-temperature test
After the machine has fully cooled and all filters and ducts are clear, restore power and run a 30-minute Synthetics or Low-Heat cycle with a small test load. Stay with the machine for the full cycle and check that the exhaust airflow at the vent feels strong and steady.
Weak airflow at the exhaust vent during the test cycle confirms a remaining blockage somewhere in the duct run even if the filter and condenser appear clear.
When to Call a Professional
Contact a qualified technician if:
- E2 recurs consistently despite clean filter, condenser, and clear exhaust duct — thermostat replacement required.
- Thermostat continuity test shows it trips at the incorrect temperature — professional calibration or replacement needed.
- Thermostat and heater assembly work on Asko dryers starts from $140.
