Drain machine by running the outlet pipe into a bucket at floor level or run the outlet pipe out of the back door if it'll reach. Power off, drag machine out onto the floor, remove back cover or tip machine up at an angle. 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. When replacing the heater ensure it locates properly in its retaining clip inside the drum. This stops it contacting the moving drum- VERY IMPORTANT.
