My press had same problem....
Remove top 4 rivets
Remove switch pannel 2 screws (Note wire positions)
A 1.5Kohm resistor is sleved and mounted on the back of the PCB. (brown-green-red) 1 watt rating
This was open circuit in my case
Depending on your skills this component could be changed by using the wire ends of the old comonent
Otherwise remove the PCB by desoldering the pins on the switch then proceed to unsolder the resistor and replace as I did.
No other fault was evident and the press once again works
