Question: Does this percolator contain any aluminum parts that contact the water?
Document: I have been searching, reading reviews, contacting companies, trying as hard as I can to find an all stainless steel percolator with no plastic, aluminum, etc. coming in contact with my water/coffee. I'm almost ready to give up and conclude that there is nothing out there that is JUST stainless steel on the inside! I thought I had found it in this Hamilton Beach Stainless Steel Percolator (model 40616).
Although the books I am reading tell me otherwise, percolated coffee starts my day just fine! With freshly ground beans, that morning cup can be outstanding. Have not had a problem. I am picky also, and will not tolerate aluminum parts.
If you have no concerns about plastic and aluminum contacting the hot water while brewing your coffee, I'm sure this would be a great percolator. Sadly, I can't use it. I can't believe I can't find an electric percolator totally free of aluminum and/or plastic in its interior.
This has made about three pots a week for over four years. Just keep it clean, and do not immerse it in water. The best way to clean it is as follows: Pour 1/3 cup of baking soda in the pot, fill it with water to the 12-cup level, install the internal metal parts, and let it peculate until it is done. Pour out the water, rinse and clean the inside and each of the metal parts .
Hamilton Beach told me (twice) that this percolator (model #40616) is only stainless on the interior, with no plastic, aluminum, coating, or other materials. I specifically asked about the heating or perk well, since I have found that several other companies use aluminum in the heating wells. I was told the entire interior, including the well, is stainless steel. So I ordered this percolator, hoping my search had come to an end.
The percolator arrived today. Before ordering, I had called Hamilton Beach and verified that the inside was completely stainless steel, without aluminum or plastic. This is the second percolator I have to return to Amazon, who has been very accommodating. I fault the manufacturer for providing misinformation about the products. The first I tried was a Presto and the indentation into which the stem sat was aluminum. The same part in the Hamilton Beach is plastic. It also has two screws on the inside to which the outside handle attaches.
This percolator makes good coffee until the electrical parts start failing within a few months. First I had to wiggle the power cord to make connection. This worked for a couple of months. Now it immediately goes into warmer mode when it is first plugged in. It will not percolate. Don't buy this poorly made unit. Waste of money. I was extremely careful not to immerse or soak the unit when washing, but still total failure in a few months. Junk.
I've had this Percolator for several years. It's great and very fast. I lost the plug-in due to a recent move and had no trouble at all replacing it. Hamilton Beach also sent me a list of all the replacement parts available for this Model 40616 - should I need them at a later date. My coffee stays hot and fresh and never scorched. If I ever have to replace it (which I doubt), I'll get the exact replacement. It's the best coffee maker I've ever had.
The stainless steel basket, lid and stem all seem of adequate quality. It is so much easier to keep the s.s. steel basket clean than the aluminum ones--even the vintage cheaper pots had aluminum.I've read somewhere around here that this is supposed to have a 'retro' look. That's a laugh! Go back 40 years and everyone was trying to make these look like spaceships!
This is a heavy duty coffe maker (percolator) that works wonderfully. It heats quickly and keeps water hot for a long time.
Answer: All the parts are stainless steel.   We are very pleased with it but the lid is somewhat difficult to remove and replace.
