HB 40515 coffee pot.

You can find the stem and other parts at: http://www.abtecparts.com/hamilton_beach_coffee_urns.htm. The GE urn and the Hamilton Beach counterpart are the same item.

Most coffee makers use a small check-valve in the feed line to the coffee basket and if a small particle gets trapped in it, the pumping action becomes erratic or very slow. To be sure any lime deposits are dissolved, use < 1 cup of Lime Away or similar product such as CLR. Make sure there is no water left in the reservoir and pour the product into it. With no coffee in the basket and the pot in place, turn on the machine and watch for the first drops into the pot, then turn off the machine again.
Let it stand for a couple of hours (I'd recommend against leaving it overnight) and then turn it back on to let it finish pumping the reservoir empty. Check the sediment in the bottom of the pot and if you see any 'crud' such as particles of lime or even a granule of coffee, you may have solved the problem.
If that seems to be the case, flush the machine with a tablespoon of baking soda and then clear water.
Good luck-

Rule#1: NEVER immerse the percolator in water--there are electrical components in the plastic base that will not react well to that kind of treatment.

The outside, cover, basket and stem can be cleaned with warm, soapy water. You can fill the pot with warm soapy water as well, although to remove mineral deposits and the like, it's recommended you periodically run a brew cycle (with stem and basket in place) using a solution of 50% vinegar and 50% water. To remove tougher stains, you might want to instead try dip-it coffeemaker cleaner.

Hi. The spring slips onto the stem just under the coffee basket, it holds the stem with pressure so the perked coffee go up the stem onto the spreader, check repairshack.com Ron

Hello,

If you go onto the Hamilton Beach website and look at products there is a tab for spare parts.

I just called the company and ordered a new lid and a manual . It cost a little over ten dollars.

Water Level ////Amount of Ground Coffee

42 Cups --2 ½ Cups
36 Cups-- 2 Cups
30 Cups- -1 ¾ Cups
28 Cups --1 2/3 Cups
24 Cups --1 ½ Cups
22 Cups --1 ½ Cups
18 Cups-- 1 ¼ Cups
12 Cups --1 Cup

1. With basket and stem removed, fill coffeemaker with COLD water to desired level using the cup markings on inside of coffeemaker as a guide. Do not make less than 12 or more than maximum capacity of the coffeemaker at one time.
2. Place stem into heating unit in bottom of coffeemaker, then put basket on stem. Spread the recommended amount of ground coffee evenly into the basket. See chart. Use regular electric perk grind coffee or coffee ground for all coffeemakers. Do not use drip or finely ground coffee as flooding of the basket can occur.
3. Turn cover in place on coffeemaker. To reduce coffee spills, especially if coffeemaker is tipped over, make sure cover has been turned clockwise until it is completely secured in the handle slots. (Note the arrows on the cover for correct turning.) The cover temporarily reduces coffee spilage if coffeemaker is tipped over, so care should be used when moving coffeemaker.
4. Place coffeemaker on a dry, level surface. Attach cord to coffeemaker and plug into a 120 volt AC electrical outlet ONLY.
5. Coffeemaker stops perking automatically. (Each cup of coffee requires about 1 minute brewing time) Serving light will glow when coffee is ready. Before serving, use a hot pad to remove cover, then carefully remove stem and basket from coffeemaker as coffee and grounds are HOT. If not removed, bitter oils from the coffee grounds will drip into coffee. Replace the cover making sure it is completely secured into the handle slots.
6. Coffee will remain at serving temperature as long as coffeemaker is connected to outlet. (if you have an insulated coffeemaker, the sealed-air insulation will keep coffee hot for up to two hours without electricity.) To serve, place cup and saucer under faucet and press down on handle. If a continuous flow is desired to fill a carafe, lift handle straight up until it locks into open position. When approximately one cup of coffee remains in coffeemaker, disconnect from outlet.
TO MAKE MORE COFFEE: If another pot of coffee is desired right away, partially fill coffeemaker with cold water to reset the thermostat. Pour out water, refill with cold water and repeat steps 1-6.
TO HEAT WATER FOR INSTANT BEVERAGES: Plain water may be heated in your coffeemaker for use with instant beverages. Simply fill the clean coffeemaker with cold water to the desired cup level, and then place the stem and empty coffee basket in place. Using the stem and empty basket will heat the water more uniformly. Secure cover in place and plug coffeemaker in. Heat water until perking stops and serving light comes on. Unplug coffeemaker when less than 1 cup remains. Other than making coffee or heating water, no other liquid should be heated in coffeemaker as damage to heating unit can occur.
When coffeemaker is used to heat water only, the metal inside will discolor which is normal and does not affect performance or the water heated in the coffeemaker. Refer to Special Cleaning Instructions in this manual for removing discoloration as well as mineral deposits, which form inside the coffeemaker when heating water. If these deposits are not removed, pitting of the metal inside may occur and result in damage to coffeemaker. Refer to the cleaning your coffeemaker section

Simply fill with COLD water to the number of cups desired.
Place the stem and basket in the pot and put one 8 oz cup of coffee for every 20 cups of water into the basket...when doing 100 cups I add an extra 12 oz of coffee for a good coffee flavor.
Place the perforated lid on the coffee basket that is in the pot (if there is a lid--some do not have a lid). Put the cover for the coffee pot in place.
Plug in.
Turn on if there is a switch.
Give these large pots about 1 minute per cup, brewing time...that is a little over an hour usually to brew 100 cups. The coffee maker will percolate with the water coming up through the stem and over the coffee as the water heats. Usually there is an indicator light that comes on when it is finished.

If holding the coffee for awhile, it tastes best if you remove the stem and basket and it will maintain the heat without doing more "perking" and becoming stronger or bitter.

Be sure to wash it out and dry it well, leaving the lid loose or upside down for storage so that the pot doesn't become pitted. Blessings, Louise

do not fil the pot past 8 cups, you have to give some space for the water to circulate while running the cleaning solution.
