240HC mk2 problem with FBV express

[Merderface]

Hi! 

I use Spider v 240HC (2.05) with FBV express mk2

When I pick up master I hear frequent clicking sounds. The sounds clearly come from the expression pedal. If you change the position of the pedal, you can also hear accompanying sounds.

I thought the pedal was defective. Connected it to Spider Jam - everything works fine. No otherworldly sounds at any volume level.

Now I can’t figure out what to bring for repairs - нead or controller.

 

Please help (
