It seems the motor on my Breadman Ultimate 2200C has burned out.

Sounds like you have burned up the drive motor,.

Found your breadman TR500 paddle at the following site
Hope this helps

Check to see if the power cord gets power to the machine. Often, that is a problem for a number of small kitchen or household electrical appliances. Replace it if not functioning, OR, if you can find where the break in ythe line is ( if that's the problem), you can cut off part of the cord at the break and re-attach the cord to the machine. Hopefully, THAT'S the problem ( or maybe a fuse or reset switch/button). The worst would be if the motor field coil windings burnt. Also, inside the motor, maybe the carbon contacts to the motor's armature may just need to be replaced.

use the dough cycle

Hi, sorry your dispenser appears not to be working. Unless and until you can repair it you can always add fruit and nuts the old fashioned way. Take a look at your manual and find the program you are using. Find how long the 2nd knead cycle lasts. For example lets say your 2nd knead last 20 minutes. Plan on opening the lid of your machine 10 minutes into the 2nd knead. All bread machines recommend add-ins well into the 2nd knead. Just have your ingredients premeasured on a paper plate next to the machine and fold the plate and pour them in halfway into the 2nd knead of the program you chose. At least that will help you get the bread you wanted.

Are you making a different kind of bread than you did the first time?. If so some machine programs have a delay before they start kneading such as the whole wheat cycle. Also some machines delay the kneading process while they warm up the ingredients. If it is colder where you live now than itw was 6 days ago that could be a factor.

Silly question but are you giving it a slight turn until it clicks in? :)

I had a similar problem after using the same machine for several years. It worked well for years and then popped off the shaft whenever I had a rather stilll dough. To solve the problem I bent the clips on each side of the bread pan that hold the pan into the machine up and toward the center of the machine. I did not use any tools to do the bending. It solved the problem. The pan no longer jumps up out of the clips and off of the shaft.

Me too! I have to bend the two metal pieces on the sides out before every use - they are pretty flexible, you won't break them. Just bend out and they hold the pan in for a use or two. Not an elegant solution, I admit, but it works.

Check your measurements.
Sounds like operator error.
