Query: Would be great IF it worked

I bought this for a gift and it worked great for less than a month. Refilling it is difficult but not a deal breaker. However, after refilling it only twice (not a lot of use) the motor's running but nothing's coming out. What a waste if we can't fix it because Amazon will not exchange or refund for it. I read another review that there's a small spring that comes off with refill and ends up in the grinds, can't find that either. (that was appealing). So I guess if you keep it operating it's super and we loved it but now it's broken it's a project to fix in the workshop.
