1) Adjust the speed sensor 2) Tight very well the connection from speed sensor. 3) Faulty Sensor speed 4) Faulty Main Motor measure for 115 VAC without load. 5) Main motor board faulty , test for 115 VAC,and oupput for +5Vdc. 6) See the transformer for 115 VAC,for primary voltage and secondary voltage. 7) See if some component such: resistors, capacitor, diode, or IC burn. 8) Lubricate the deck belt. 9) Adjust the tension for deck belt for lift 2-3" max. 10)error code e1 vs e2 in some mark is equal is different from some manufacturer. See the block diagram for your diagnostic, for strong resultant.
