| 1 | Machine does not work; power indicator does not light up at switch on position. | 1. No AC supply 2. MCB tripped 3. Mains cord failure 4. Power switch failure | 1.Restore AC supply 2. Check for any short circuit and reset the MCB. 3. Replace mains cord. 4. Replace the switch. |
| 2 | Vacuum pump does not work when lid is closed and vacuum level is always displayed. | 1.Micro switch does not operate. 2.Defective micro switch. 3.Defective contactor (coil open or contact burned out). 4.Defective relay. 5.Defective motor. | 1. Adjust switch operating lever screw suitably to operate the switch when lid is closed. 2.Replace the micro switch. 3.Replace the contactor. 4.Replace the relay board. 5.Replace or rectify the motor. |
| 3 | The lid does not remain closed even after vacuum pump starts | 1.Lid gasket does not touch the chamber face uniformly. | 1.Press the lid with both the hands at the corner of lid. 2.Check the gasket for any damage and replace if necessary. 3.Check the height of lid hinge. If the hinge height is optimum, the lid can be closed easily and the gasket touches the chamber uniformly. |
| 4 | Insufficient Vacuum Reading | 1.Low vacuum setting 2.Solenoid valve leaks: atmospheric air enters in to the chamber through the solenoid valve due to, a)Defective solenoid valve. b)Defective relay. 3.Low oil level in the vacuum pump. 4.Moister contaminated oil . 5.Vacuum leaks through lid gasket/bolt holes on the lid/pipe joints/bushes at cable entry. 6.Wear and tear of vanes of vacuum pump. 7.Defective transducer Board or twisted cable to transducer board. | 1.Increase the vacuum setting. 2. a)Replace the solenoid valve. b)Replace relay board. 3.Keep the required oil qty in the vacuum pump. 4.Drain the oil completely and refill. 5.Identify the location of leakage and replace the defective components or rectify the problem by tightening the joints. 6.Overhaul /replace the pump. 7.Replace the defective. |
| 8 | Sealing head operate but sealing does not takes place | 1.Low sealing time setting. 2.heating element failure. 3.Defective sealing transformer. | 1.Increase sealing time. 2.Replace heating element. 3.Replace defective sealing transformer. |
| 9 | Machine halts after sealing | 1.Defective relay. 2.Defective air inlet solenoid valve. | 1.Replace the relay board. 2.Replace solenoid valve. |
| 10 | Pouch expands during vacuum time | 1.Low gap between sealing head and pad holder assembly. | 1.Increase the gap by adjusting the pad holder assembly. |
| 11 | Nonuniform sealing | 1.High gap between sealing head and pad holder assembly. 2.Sealing head and pad holder not align properly. 3.Burnt Teflon fabric. | 1.Reduce the gap. 2.Align sealing head and pad holder. 3.Replace the Teflon fabric. |
| 12 | Machines works fine, but blank/garbage display | 1.Defective display. 2.FRC cable of display or its connector defective. | 1. Replace display board. 2.Replace cable and connector. |
| 13 | The Microcontroller does not responding to push button pressing. | 1.Defective switches. 2.Defective FRC Cable of Display PCB | 1.Replace display board. 2.Replace cable and connector. |
| 14 | System hangs during operation | 1.Temporary bug in program due to noise. 2.Defective micro controller board. | 1.Switch off and restart the machine. 2.Replace Microcontroller board. |
| 15 | Display does not change from fresh air to ready | 1.Misalignment of reed switch. | 1.Correct the position of reed switch. |
| 16 | Overheating of Heating element/Transformer | 1.Short circuit with body of machine. 2.Defective Relay/IRF 540 of heater in Relay PCB | 1.Make proper wire connections. 2.Replace Relay PCB. |
| 17 | Machine trips while pump starts working or abnormal sound of pump. | 1.Winding short with body. 2.Defective centrifugal switch. 3.Defective love jaw coupling bush. | 1.Rewind or replace the pump. 2.Replace the switch or pump. 3.Replace the bush or pump. |
| 18 | Display shows fresh air always | 1.Misalignment of magnetic reed switch. 2.Magnetic reed switch shorted. | 1.Correct the position. 2.Replace the switch. |
| 19 | Improper sealing | 1.Misalignment of sealing bed. | 1.Correct the position. |
| 20 | Lid doesn’t open after completing the operation. | 1.Defective relay in the relay board. 2.Defective solenoid valve. | 1.Replace it. 2.Replace it. |
