  If the Esco Vacuum Cleaner LCD is blank, consider these solutions: * Check that the LCD FRC (Flat Ribbon Cable) is properly inserted into its socket on the main board. * Adjust the potentiometer (blue color, next to the connector to Relay Board) on the main board to optimize the LCD contrast. * Connect a working LCD to the LCD port of the main board. If the working LCD functions correctly, the original LCD is likely faulty and needs replacement.

  If the light is always off on your Esco Vacuum Cleaner, check the LS7 relay and fuse F7 on the relay board. Replace the fuse if it's blown. A temporary solution is to take out fuse F5 and put it in place of F7. At terminal J13, ensure that the C-NC connection is closed and the C-NO connection is open. If the relay board is faulty, it should be replaced. Contact your distributor for further assistance.

  If the buttons on your Esco Vacuum Cleaner are inoperative: * Check if the green plastic cable from the membrane is properly inserted into the interface board. Also, verify that the interface board is correctly connected to the main board through an FRC, ensuring the triangle sign on the female connector indicates PIN 1. * If the connections are secure, try replacing the cable, interface board, and keypad one by one to identify the spoiled part(s). Replace the faulty component(s).

How do I resolve a 'filter loaded' alarm on my Esco ASCENT OPTI BASIC?
- A
  Amy AndersonSep 9, 2025
  To address a 'filter loaded' alarm on your Esco Vacuum Cleaner, plug in the multimeter to the Motor Voltage Sampling Port. Turn the Speed Control to increase the blower voltage by approximately 10 VAC until the alarm is turned off and the LCD shows nominal airflow reading. Allow the sensor 2-3 minutes to register the new airflow setting. If the blower is already at maximum voltage and the alarm persists, it's time to change the filter.
