Beverage Cup Sealer Troubleshooting: Sealing Film Keeps Spinning [Error Code E07] | Phoenixes - Sealing Machine Repair Tutorial
When the sealing machine displays the E07 error code, it usually indicates that the machine has detected an anomaly related to the safety mechanism. This error is typically not a severe internal hardware failure but is related to external operation or minor deviations in mechanical positioning.
Error Code: E07 - Common Causes
| Component | Anomaly | Detailed Explanation |
|---|---|---|
| **Safety Door** | Mechanical Deformation or Positioning Deviation | Slight deformation of the safety door due to prolonged use or external force prevents it from correctly triggering or releasing the micro-switch, causing the system to mistakenly detect the door as open or stuck. |
| **Emergency Stop Button** | Accidental Activation or Not Reset | The red mushroom-head button on the front of the machine was accidentally pressed. When the button is depressed, the system enters protection mode and issues the E07 warning. |
✅ Simple Troubleshooting Methods
Step One: Safety Door Calibration
1. Visual Inspection: Carefully observe the edges and tracks of the safety door for any visible bending or jamming.
2. Manual Adjustment: While the machine is OFF or DISCONNECTED from power, gently adjust the safety door outwards slightly to return it to its standard straight position. Ensure the safety door accurately releases the micro-switch it depresses.
3. Retest: Power on the machine and check if the E07 warning is cleared.
Step Two: Check Emergency Stop Switch Reset
1. Status Confirmation: Check the red emergency stop button on the front of the machine. If the button is depressed or locked, it means it is in the emergency stop activated (protection) state.
2. Perform Reset: Rotate the red button clockwise. When you hear a "click" and the button pops out, the switch has been successfully unlocked and reset.
3. Retest: After resetting, the E07 error code should disappear, and the machine should return to normal operation.
Follow-up and Tips
After completing the two simple steps above, perform the following check:
Warning Cleared (Normal): If the screen returns to the normal standby display, the fault has been successfully resolved, and normal production can resume.
Warning Persists (Anomaly): If E07 continues to display, the issue may involve abnormal internal electronic components or wiring connections.
Suggestion: If simple troubleshooting is ineffective, it may be due to a damaged safety door micro-switch, loose internal wiring, or abnormal control board signals.
At this point, to prevent secondary damage due to improper operation, it is recommended to contact Phoenixes professional technical customer service for in-depth inspection and maintenance service.
