How to Fix Error F78

  1. Inspect the Drain Filter: Remove the lower spray arm and take out the drain filter. Check for debris or blockages that could hinder water flow.
  2. Check the Drain Pump for Blockages: Access the drain pump by removing the cover. Inspect for any foreign objects or clogs that may be obstructing the pump.
  3. Test the Drain Pump Motor: Using a multimeter, check the resistance of the drain pump motor. If it reads zero or infinite resistance, the motor is likely faulty.
  4. Examine the Control Board Connections: Inspect the wiring and connections to the control board for any signs of damage or corrosion that could affect pump operation.
  5. Reassemble and Test the Dishwasher: Once repairs are complete, reassemble the dishwasher and run a short cycle to check if the error persists.
