Possible Causes

Loose or damaged communication harness, failed user interface board, failed main control board, corrosion on console connectors

How to Fix / Troubleshooting

Safety First: Unplug the dryer before removing the console or top panel.

Steps:

  • Access console: Remove screws securing the control console and gently tilt it forward.
  • Inspect harness: Locate the communication harness between the UI and main control. Reseat both ends and check for pin damage or corrosion.
  • Check for moisture: Look for signs of moisture or detergent residue on the UI board. Allow to dry completely if damp.
  • Power reset: After reseating connectors, restore power and test. If F70 persists, one of the boards is likely defective.
  • Board replacement: Replace the user interface first (most common), then the main control if the issue remains.
