Electrolux Dryer Error Code Overfull

The Overfull error on Electrolux condensation dryers indicates that water has accumulated beyond the acceptable level in either the condensation water tank (on T780 models) or the internal bottom water container. Condensation dryers do not vent moisture outside through a duct. Instead, they cool the moist exhaust air to condense water vapor into liquid, which is then collected in a removable tank or pumped out through a drain hose. When the sensor detects that this water has reached its capacity limit, the machine halts operation and triggers the Overfull alert to prevent overflow damage.

The most straightforward cause is simply a full condensation tank that has not been emptied between cycles. However, if the error returns immediately after emptying the tank, the problem shifts to the drainage system. The condensate pump is responsible for moving water from the bottom container to the tank or out through a drain hose. If this pump is blocked by lint or debris, has failed electrically or mechanically, or if the connected hoses are kinked, pinched, or clogged, water cannot be evacuated properly. The bottom container then fills up and triggers the overfull condition even though the removable tank appears empty.

Diagnosis should begin by emptying the condensation tank completely and restarting the dryer. If the error reappears during or after the next cycle, inspect the drain hose along its full length for kinks or obstructions. Next, check the pump inlet and outlet hoses for blockages, which are often caused by lint accumulation. The pump itself should be checked for continuity and mechanical freedom if hose inspection reveals no blockage.
