Taskalfa 356ci error 1800 Cassette 1

[New Tech Guy]

Hey guys, I have this 356ci machine that is giving an error 1800. What I have done are:

1. Confirmed that the wiring connected
2. Updated the firmware
3. Replace the PF main PWB

Those are the steps I basically did in shop with the manual. Any suggestions?

If you have unplugged the connections and re-plugged them and made sure they are connected good then maybe it is the wire that needs to be replaced per the manual. I would tone out the wire connections on the wire and if that is good then the next step is the Engine PWB. I have never had to replace a wire assy. It is always been the plug was not plugged in good or properly or a board.

Check the self-connected plugs of the system and PF.
The most common problem was that something was bent
