Precor elliptical exercise Machine (efx 556) is not recognizing that we have started pedaling. It takes input of program, weight age etc, as normal but then will not actually get started - continues to display the "start pedaling" banner and does not provide resistance (we are pedaling). Worked fine until yesterday. Any thoughts much appreciated
