B- Checking the front of the machine
If the vacuum pump motor does not run, check the electrical supply. If the motor smells strongly of burnt
lacquer then it is probably burnt out and the entire pump/motor assembly needs replacing.
If all the connections are good then the switches can be checked for continuity.
Note: Continuity should be obtained between the top and bottom contacts of the switch not side to side.
If the supply is present but the motor hums and does not run, the capacitor may be faulty or has become
disconnected. Check the connections to the capacitor by carefully removing its black cover.
Remove the 4 cap head screws with an allen key 3mm.
Remove the front panel and check the pump switch connections.
