Error: Major Vacuum Error check list
1. Check the pump cable plug if it fits in the socket properly
2. Connect power cable directly to pump cable to check if the pump works
3.See if the O ring seats in the place accurately. Press the ring evenly as you put it on the table upside down. It is a good idea to use some baby powder if the ring is sticky.
4. Activate the lift upward using the arrow on the screen. Make sure that the plate closes tight when lifted. If the vacuum pump doesn’t start, push the plate upward slightly with your fingers to activate the lift switch and the pump. When the lift closed the furnace spring system must work for an accurate touch of surfaces to prevent the vacuum leak. Lift adjustment may be necessary!.
5. Start a program to check if the vacuum is rising on the green bar. You must get 200 mm at least. If not, vacuum calibration is necessary.
