| 1 | Machine does not work; Phase sequence LED light up | 1.Absence of one phase. 2.Mains cord failure. 3.MCB failure. 4.Phases are not in sequence. 5.Imbalance between phases. | 1.Restore AC supply. 2.Replace mains cord. 3.Replace the MCB. 4.Inter change any two phase lines. |
| 2 | Vacuum pump does not work when lid is closed and vacuum level is always displayed | 1.Defective contactor (coil open or contact burned out). 2.Defective relay pcb. 3.Defective vacuum pump. | 1.Replace the contactor. 2.Replace the relay board. 5.Replace or rectify the vacuum pump. |
| 3 | The lid does not remain closed even after vacuum pump starts | 1.Lid gasket does not touch the chamber face uniformly. | a.Press the lid. b.Check the height of swing arm. If the height is optimum, the gasket will touch 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 microcontroller 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. |
| 5 | 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. |
| 6 | Machine halts after sealing | 1.Defective relay used for flushing. 2.Defective air inlet solenoid Valve. 3.Selection of Mode is wrong | 1.Replace the relay board. 2.Replace solenoid valve. 3.Set correct Mode. |
| 7 | Pouch expands during vacuum time | 1.Low gap between sealing head and pad holder assembly. 2.Defective solenoid valve | 1.Increase the gap by adjusting the pad holder assembly. 2.Replace defective. |
| 8 | 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. |
| 9 | 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. |
| 10 | Setting is not possible. 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. |
| 11 | 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. |
| 12 | Overheating of Heating element/Transformer | 1.Short circuit with body of machine. 2.Defective Relay PCB/Contactor | 1.Make proper wire connections. 2.Replace the defective. |
| 13 | 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. |
| 14 | Lid doesn’t open after completing the operation. | 1.Defective relay in the relay board. 2.Solenoid valve coil burned out. | 1.Replace it. 2.Replace the solenoid valve. |
| 15 | Display shows fresh air always | 1.Misalignment of micro switch. 2.Defective micro switch. | 1.Correct the position. 2.Replace the switch. |
| 16 | 24V Transformer Fuse blown out. | 1. Solenoid coil burned out. | 1.Replace it. |
