We're so sorry to hear that your Suvie Starch Cooker is leaking, we certainly understand how frustrating this is and we're happy to help.
Before each cook, check to make sure that the drain tray is completely empty. Failure to do so will result in the drain tray overflowing after the cook.
Be sure to never add additional water in the water reservoir after the cook has begun. If water is added once the device is cooking, this can cause excess water to drain out and overflow the drain tray.
