Hello.

I have a problem with my Clark gex30l 2015 electric truck. It won't go forward or backward. Sometimes I get these error codes, other times no errors at all.
109: vmn low
139: capacitor charge
172: vmn low

both front wheels are completely locked. even if i lift it up they can't be turned by hand. is that supposed to be the case, or could something have happened to both drive motors?

I suspected the brakes at first, but they are wet brakes so they shouldn't get stuck.

This error has occurred while the truck has been standing still for 6 months. Before that there was no error.

I am grateful for the tips and advice.
Best regards Jim
