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.

Questions people ask about Overfull

What does Overfull mean on a Electrolux dryer?
The Overfull error means the condensation water tank or the internal bottom water container has reached its maximum water level. Electrolux condensation dryers collect moisture removed from laundry as liquid water, and this water must be emptied regularly or drained through a hose. The dryer stops running when it detects an overfull condition to prevent water from spilling inside the appliance.
Will resetting the dryer clear the Overfull error?
A simple reset will not permanently clear the Overfull error if the underlying cause has not been addressed. The error will return as soon as water accumulates again in the tank or bottom container. You must empty the tank and confirm the pump and hoses are functioning correctly before the error will stay cleared.
How much does it cost to repair an Electrolux dryer showing the Overfull error?
If the fix is simply emptying the condensation tank or clearing a kinked hose, there is no parts cost involved. If the condensate pump needs to be replaced, parts and labor costs typically range from around $100 to $250 depending on your location and the service provider. Clearing a blocked pump or hose without replacement parts usually falls at the lower end of any service call fee range.
How do I fix the Overfull error on my Electrolux dryer?
Start by removing the condensation water tank, emptying it fully, and reinserting it, then restart the dryer. If the error returns, check the drain hose for kinks along its entire length and clear any blockages. Also inspect the condensate pump and its connecting hoses for lint buildup or obstructions. If the pump is clean and the hoses are clear but the error persists, the pump itself may need to be replaced.
Is it safe to keep using my Electrolux dryer when the Overfull error appears?
You should not continue running the dryer with the Overfull error active. The machine is designed to stop automatically to prevent water from overflowing inside the cabinet, which could damage internal components or create a slip hazard if water reaches the floor. Resolve the cause of the error before resuming use.
