Asko Oven E03 Error: Lower element fault
Asko oven E03 error is a common issue reported by Asko appliance owners. What Does Asko Oven Error Code E03 Mean? E03 indicates a fault in the lower bake element circuit. Because this element handles the majority of cooking heat, E03 effectively prevents normal baking and roasting until the circuit is restored. Common Causes Burned-out […]

Answer to continue safely
Is it safe to keep using?
No. Baking and roasting are not possible with a failed lower element. Using the oven with an unresolved E03 fault risks worsening the electrical fault.
Can I reset the code?
Yes. Resetting via the breaker clears the code temporarily, but E03 will return as soon as the oven next tries to activate the lower element.
When to stop immediately?
Stop if you notice: Stop immediately if you notice sparking or a flash inside the oven cavity., Do not use the oven if there is a persistent burning smell even with no food inside..
Symptoms You May Notice
Oven fails to reach set temperature
With the lower element out of service the oven may only partially heat from the fan element, resulting in long preheat times and uneven cooking.
E03 appears on the display panel
The control panel shows E03 immediately when the bake programme is selected or during an ongoing cook cycle.
Food undercooked on the bottom
Baked goods cook from the top only, leaving the bottom pale or raw because the lower element is not producing heat.
Burning smell from element area
A food spill that has shorted or burned the element produces a persistent burning or acrid smell before the fault code is logged.
Possible Causes
Burned-out bake element
Food spills on the lower element cause localised overheating, leading to the coil burning through and creating an open circuit.
DIY PossibleThermal-shock crack in element
Pouring cold liquid into a hot oven can crack the ceramic element sheath, eventually causing an internal open or short circuit.
DIY PossibleControl board relay failure
The relay responsible for switching the lower element has failed in the open position, preventing any current reaching the element.
Requires ProfessionalSafe Checks You Can Do
-
1
Visually inspect the lower element
Turn off power at the breaker and allow the oven to cool completely. Remove any oven racks, then look at the lower element surface for blisters, cracks, burn holes, or bright spots.
A crack in the element sheath, even a hairline one, means the element needs replacement.
-
2
Clean the oven cavity floor
Heavy carbonised food deposits under or on top of the lower element can arc to the cavity floor. Clean thoroughly with oven cleaner and allow to dry before testing.
Never use abrasive pads on the oven cavity coating — they damage the finish and make future cleaning harder.
-
3
Test element resistance
Disconnect the element terminals (two spade connectors at the rear wall) and measure resistance across them with a multimeter. Expect 20–40 Ω for a healthy Asko lower element. OL or zero Ω confirms failure.
When ordering a replacement element, cross-reference the model number on the rating plate — elements vary in wattage between Asko oven families.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Element resistance is within specification but the fault persists after reconnection.
- Visible arcing marks on the oven liner adjacent to the element terminal holes.
- The replacement element fails within a short time, suggesting a wiring or board fault.
