Cuisinart EPS-14 Electric Nonstick Poacher/Steamer, Stainless Steel

I want to poach my fish and chicken, not boil them. However the temperature control set to 200 which is recommended will go in and out of a rapid boil. I have to turn it way down to warm to keep it out of the boil and then the recipe times do not work. It has a broad range of degrees before it clicks on to warm the water again. Just not precise enough to set with in a specific poach temperature range. I contacted Cuisinart and they said they did not have a replacement temperature control prong plug insert (apparently out of production with no replacement parts) She said she did not even have a demo to try it out but found a picture of it. She recommended I contact the seller. I did contact my seller but never got a return on my complaint. I decided to work with it defective as it was but now I wish I had returned it. I never use it.
