What This Error Means
The H2O full fault code on your Fisher & Paykel Dryer means: The water collection tank on a condenser or heat pump dryer is full and must be emptied before the dryer can continue. This is routine maintenance, not a fault. Also displayed as H2O full on some models.
Most common cause: tank not emptied after previous cycles.
No professional service needed.
