Two options. Either disconnect the sump hose (the big one which connects to the filter or pump) from bottom of drum and try to wiggle the item out. If that doesnt work you'll have to disconnect and remove the heater which should give another vantage point. Use a torch and a long thin stick to move the item to the sump outlet.
