| 1 | Machine does not work; power switch does not light up. | 1.No AC supply. 2.Mains cord failure. 3.MCB failure. 4.Power switch failure. | 1.Restore AC supply. 2.Replace mains cord. 3.Replace the MCB. 4.Replace it. |
| 2 | Vacuum pump does not work when lid is closed and vacuum level is always displayed | 1.Defective contactor 2.Defective Relay board. 3.Defective motor. | 1.Replace the contactor. 2.Replace the relay board. 3.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. | a.Press the lid. b.Check the height of swing arm. If the height is optimum, the gasket will touche 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. | 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 |
