When the above machine is turned on, all the lights stay on permanently for 10 seconds or more.
If the lights eventually go out, you can set a program but when you try to start it, all the lights flash.
Sometimes the machine refuses to turn off.
I have checked for loose connectors and checked the insulation of the machine.
I have done a factory reset but this doesn’t change anything.
Following a factory reset, should be machine start using the default settings or is there anything that has to be set-up/configured first?
Are there any known issues with the PCBs on these?
Could the customer have corrupted the PCB trying to upgrade the software?
