Troubleshooting and error codes
| PROBLEM | POSSIBLE CAUSE |
|---|---|
| Draught circulates around the door. | When oven is working, air circulates within the cavity. The door does not form an airtight seal so air may escape from the door. |
| Condensation forms in the oven, and may drip from the door. | The oven cavity will normally be colder than the food being cooked, and so steam produced when cooking will condense on the colder surface. The amount of steam produced depends on the water content of the food being cooked. Some foods, such as potatoes have a high moisture content. Condensation trapped in the door glass should clear after a few hours. |
| Flashing or arcing from within the cavity when cooking. | Arcing will occur when a metallic object comes into dose proximity to the oven cavity during cooking. This may possibly roughen the surface of the cavity, but would not otherwise damage the oven. |
| Arcing potatoes. | Ensure all "eyes" are removed and place in a heat resistant flan dish or similar. |
| After setting the time, the oven does not start. | Check the door is closed properly. |
| Oven cooks too slowly. | Ensure correct power level has been selected. |
| Oven makes a noise. | The microwave energy pulses ON/OFF during cooking/defrosting. |
| Outer cabinet is hot. | The cabinet may become warm to the touch - keep children away |
