I'd contact Hamilton Beach about this -- their web site for this model coffee maker might have a "frequently asked questions" type of page that covers it, or you can e-mail their customer service. I've had good luck doing this with other products when I had questions (though I haven't had to contact this particular maker).
I would add --if you cannot use these cocoa "pod" cups please don't just throw them out. Give them to a friend with a compatible coffee maker, or toss them into the car so that if you go to the hairdresser and they have this type of maker, you can give them the pods, or take them anywhere they can be reused. These days, our orthodontist's office, hairdresser, dance studio "parent area" and other service providers all have Keurig or Keurig-like single-cup makers. It would be a shame to throw them away if someone else can enjoy them, and you can tell your husband he made parents or patients or clients happy!
