E07 appears and the unit beeps continuously; the display may show a descaling or maintenance icon.

Safety: Allow the unit to cool and unplug before internal inspection.

• 1. Perform a full descale:
  • Fill the reservoir with a 1:1 white vinegar and water solution.
  • Run the dedicated descaling program if available, or several full brew cycles without coffee grounds.
  • Let the solution sit in the system for 15–20 minutes between cycles to dissolve scale.
  • Flush with at least 2–3 full reservoirs of clean water.
• 2. Reset the descale indicator:
  • Consult the user manual for the specific Frigidaire model's reset procedure (often holding the brew and power buttons together for several seconds).
  • Perform the reset and check if E07 clears.
• 3. Inspect flow sensor (if equipped):
  • Some models use a small turbine flow meter in the water line.
  • Access the internal tubing and locate the flow sensor; check for debris or scale blocking the turbine.
  • Clean or replace the flow sensor if it does not spin freely.
• 4. Evaluate control board:
  • If E07 persists after descaling and reset, the control board's maintenance counter or sensor input may be faulty.
  • Inspect the main control PCB for corrosion or damage and replace if necessary.
