Hi! I have started experiencing the problem with the unit - it starts up irregularly. When I turn the key on, the display lits up fine. But it might take quite a few attempts of stepping on and off the foot plate before the unit starts up. Sometimes it starts up from the first go. I thought that it might be a loose contact at the foot plate micro switch or maybe the switch itself is playing up. I have replaced both foot and motor brake micro switches but the problem is still there.

Any help you could provide would be great, Thank you.
