Problems that could be caused by incorrect usage
It is dangerous to improperly use a product.
Please consult the user manual for proper usage.
| Actual case | A user had been using a damaged dishwasher without fixing it. |
|---|
Since a user had been using a dishwasher with a cracked internal panel and torn packing, a large volume of water entered through the damaged part. As a result, the tracking phenomenon occurred, and the equipment was burned.
It occurs when an electrical current flows into accumulated dust which bears water such as dew or condensation, causing heat and eventually ignition.
Since a user kept using equipment with a broken door component, the vibration of the equipment caused the contact failure of an electrical circuit, which resulted in overheating and burned the equipment.
| Actual case | A user put something very light, which could be easily blown, near equipment. |
|---|
Since a user put something very light and easily blown, such as a combustible spoon, it eventually dropped onto the heater of the equipment. As a result, the heater started emitting smoke.
| Actual case | The dishes were put in and the machine turned on without first rinsing off oil, juice, and food residues (fish bones, etc.). |
|---|
Because the dishes were put in and the machine turned on without first rinsing off oil, juice, and food residues (fish bones, etc.), dirt accumulated around the heater, causing it to smoke.
| Actual case | Regular kitchen liquid detergent was used (including to remove grime in advance). |
|---|
Because regular kitchen liquid detergent was used, including to remove grime in advance, abnormal bubbles were released, causing water to leak.
| Actual case | Equipment was put into operation although a door was not completely closed. |
|---|
Since a user left a dish stuck in the door when using the dishwasher, a large amount of water leakage occurred.
