Asko Washer E7 Error: Heater / temp sensor fault
Asko washer E7 error is a common issue reported by Asko appliance owners. What Asko Error Code E7 Means Error code E7 on Asko washing machines points to a fault in the heating circuit. Either the heating element has failed to raise the water to the selected temperature, or the NTC temperature sensor has reported […]

Answer to continue safely
Is it safe to keep using?
Maybe. Cold-temperature and quick cycles will usually complete without issue. Avoid hot programs until E7 is resolved, as the machine may abort mid-cycle and leave clothes in soapy water.
Can I reset the code?
Yes. Power off at mains for 60 seconds. The error may clear temporarily, but will recur on any cycle that requires heating unless the element or sensor is replaced.
When to stop immediately?
Stop if you notice: A burning smell or any scorch marks are visible near the base of the machine., The machine trips the household circuit breaker when a heated cycle is selected..
Symptoms You May Notice
Wash cycle completes but clothes feel cold to the touch
Laundry removed from the machine lacks any warmth, and the drum feels the same temperature as the cold water supply — the heater has not activated.
E7 displayed after machine has been running for 20+ minutes
The machine runs through the early fill and initial tumble but displays E7 partway through the heat phase when the target temperature is not reached.
Selected temperature programs abort; cold wash programs complete normally
Programs set to 30 °C, 40 °C, or 60 °C fail with E7, while a cold rinse or quick cold cycle finishes without fault.
Detergent residue visible on dark clothes after washing
Insufficient water temperature prevents detergent from dissolving fully, leaving white streaks or powder deposits on fabrics.
Possible Causes
Burnt-out heating element
Limescale build-up on the heating element causes it to overheat locally and eventually burn out, leaving it open-circuit and unable to heat the water.
Requires ProfessionalFaulty NTC temperature sensor
The NTC thermistor that monitors wash water temperature may have drifted out of specification or failed completely, causing the control board to read an incorrect temperature and fault to E7.
Requires ProfessionalWiring harness fault to heater or sensor
A loose connector or chafed wire in the harness between the control board and the heater/sensor can interrupt the circuit intermittently, producing sporadic E7 faults.
DIY PossibleSafe Checks You Can Do
-
1
Run a descale cycle if available
On Asko W6000 series models, select the machine care or drum-clean program and run it with a proprietary washing machine descaler. Heavy limescale on the element can cause it to trip the thermal cutout rather than fully burn out — descaling may restore normal heating.
Use a descaler dosed correctly for your water hardness. In very hard water areas Asko recommends descaling every 3 months.

Check harness connectors (if comfortable)
Unplug the machine. Remove the rear panel. Locate the heating element terminals at the base of the tub and the NTC sensor connector (small 2-pin plug). Press each connector firmly to reseat it. Check for any visible chafing or corrosion on the wiring.
A connector that has worked loose through vibration is a straightforward fix that can save the cost of a service call.

3
Reset and run a 60 °C test cycle
Restore power and run a 60 °C cotton cycle. After 25–30 minutes, carefully touch the door glass — it should feel distinctly warm. If it is still cold, the element or sensor needs professional testing.
Do not touch the door seal — it runs hotter than the glass and can cause burns.
When to Call a Professional
Contact a qualified technician if:
- Multimeter test shows the heating element is open-circuit (resistance should be 20–30 ohms on most Asko models).
- NTC sensor resistance reading falls outside the expected range (typically 10–12 k-ohm at 20 °C) — sensor replacement required.
- Heating element replacement on Asko washers typically starts from $180 including parts and labour.
