Electrolux Dryer Error Code Overfull
The condensation water tank is full (T780), or the bottom water container is full because the pump or hoses are blocked or faulty.
What the Overfull error code actually means
Your Electrolux dryer collects the water it removes from your clothes in a tank, and that tank is now full and needs to be emptied. If the error comes back after you empty the tank, something may be blocking the dryer's internal water pump or hoses, preventing water from draining properly. The dryer stops running to prevent water from overflowing inside the machine.
