Problem summary
Your Nordmende SO10 integrated oven has stopped heating and may have blown the trip switch (RCD) on your fusebox. This is a sign that something in the oven's electrical circuit has failed. Do not attempt to reset the trip repeatedly — each time it trips is telling you there's a fault.
Likely causes
Based on 147 similar reports for this model, the most common causes are:
Heating element failure (64% of cases)
The main heating element — usually located at the base or back of the oven — burns out over time. When it fails, it can draw excessive current and trigger the trip switch.
Oven fan motor failure (24% of cases)
The convection or cooling fan motor can short internally, causing the same electrical overload effect.
Drive motor failure (7% of cases)
Less common, but a faulty motor driving the spit, timer, or other mechanism can also cause a trip.
Why this needs an engineer
All three likely causes involve electrical components connected to mains voltage. The heating element, fan motor, and drive motor are all high-current parts that can be dangerous to handle or test without proper equipment. Additionally, if the trip has blown, there may be a short circuit still present in the wiring — reset attempts without diagnosis risk repeat trips or worse.
Do not: - Keep resetting the trip hoping it stays on. - Open the oven casing to inspect the element yourself. - Attempt to replace any motor or heating component without isolating the appliance from mains power and testing for residual voltage.
A qualified engineer will: 1. Safely isolate the oven from the mains supply. 2. Test the heating element, motors, and wiring to identify which part has failed. 3. Replace the faulty component and verify it does not cause a trip. 4. Test the oven's heating function before signing off.
