Service / Repair
Electrical troubleshooting (continuation)
Before any maintenance work is carried out, electrical supply must be locked in the OFF position
or the mains lead removed.
Only a qualified electrical technician may work on any parts carrying mains voltage and should be
responsible for ensuring that the machine is in a safe condition before allowing services to be res-
tored.
Note
: Continuity should be obtained between the top and bottom contacts of the switch not side to side.
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 the supply is present but the motor does not run, the capacitor may be faulty.
Check the pump switch connections if the pump only is the problem. If all the connections are good then
the switches can be checked for continuity.
