Is the LFO light blinging 2-4-2 … 2-4-2 .. ? This is a service easter egg: when you power up with the bypass switch depressed, the pedal starts in a calibration mode, and the LFO light flashes out the software version; in this case, v2.4.2.
This suggests that your footswitch may be shorted to ground, that is, the pedal thinks it is depresses (closed) all the time. Double check the wiring of that switch, or even disconnect it for a moment to test.
Beyond that, I must defer to Brach, the technical guru, who is out at the moment on maternity leave. I will ask him to check in with this thread when available.
