This is going to be a failure with the infinite switch and this can be verified by testing each switch for continuity with the power supply to the appliance being off. On each switch, terminal L1 can be tested for continuity to terminal P when the switch is off and the P wire disconnected. If there is continuity that switch has failed. Here are the switches used with this model.
