If your commercial washer won’t turn on, check these things:
Make sure that the machine is switched on and that the power socket is in good condition.
Check for tripped switches or blown fuses in the electrical panel. Reset the switches or replace the fuses if necessary.
Check the door switch. The washing machine may not start when the door is open. Check and replace it if it is defective.
Check the control board for any signs of damage. Control boards often fail and may need to be replaced by a specialist.
