my auertech portable washer is leaking from the bottom, anyone else have this?

Yeah, this one's common and usually a simple fix. First, hand-tighten all hose connections—the inlet hose at the faucet and machine, and the drain hose. Don't over-tighten. Second, make sure you're not filling past the high water level marking in the wash tub. Also, run your hand along the hoses to check for any cracks or damage.
