All ingredients are measured exactly as specified. During the rise cycle the dough is practically overflowing. When it starts baking the dough drops with the largest amount in the center of the loaf.

I am not a baker but I do know dough rises either by the action of live yeast producing carbon dioxide or by the chemical action of bacteria + chemicals as in soda bread.
Soda bread doesn't rise very much and produces a fairly dense bread. A portion of active dough is kept from every batch to start activity in the next batch and in this way the cultures in many artisan breads are unchanged over the last century or two.

Yeast risen bread dough needs 10 minutes of energetic kneading after mixing and then about an hour in a warm place until it has doubled in volume before baking. Be sure to use live yeast and be careful with the amount of salt in the dry ingredients.

There are many recipes online.

The drip pans need replacing

If your Cuisinart bread machine is not baking the bread properly, there could be a few potential causes for the issue. Here are some troubleshooting steps you can try to identify and resolve the problem:
1. Check the Bread Pan: Ensure that the bread pan is properly inserted into the machine and securely locked in place. Make sure it is centered and seated correctly.
2. Check the Kneading Paddle: Verify that the kneading paddle is properly installed in the bread pan. It should be securely attached to the spindle at the bottom of the bread pan.
3. Use Fresh Ingredients: Ensure that you are using fresh and high-quality ingredients, including flour, yeast, and other additives. Old or expired ingredients can affect the bread's rising and baking process.
4. Verify Yeast Activation: Make sure that the yeast you are using is active and not expired. Test the yeast by dissolving it in warm water with a small amount of sugar. If it doesn't become foamy and bubbly within a few minutes, the yeast may be inactive, and you should replace it.
5. Check the Program Settings: Confirm that you have selected the correct program for the type of bread you are making. Different programs have different settings for kneading, rising, and baking. Make sure you are using the appropriate program for your recipe.
6. Monitor the Dough: Throughout the kneading and rising process, observe the dough to ensure it is properly formed and rising. If the dough seems too dry or too wet, adjust the recipe accordingly by adding small amounts of flour or water.
7. Inspect the Heating Element: If the bread machine completes the cycle but the bread is not baked, there may be an issue with the heating element. Inspect the heating element for any signs of damage or malfunction. If it appears faulty, it may need to be replaced. In such cases, contacting Cuisinart customer support or a qualified technician for further assistance is recommended.
By following these steps, you should be able to identify and resolve common issues that may prevent your Cuisinart bread machine from properly baking the bread.

There will be no need to extend the baking time on your uncooked loaf for if the loaf is uncooked as you say cooking it longer won't make things any better. I suspect you need a bit of tutoring regarding the fine art of using a bread machine.

Here is the assistance I offer:

White Flour: When using white flour select nothing less than unbleached white flour containing 12 to 16% protein (or 3 to 4 % per ¼ cup serving). Storage: Flour absorbs ambient humidity hindering it from blending with liquid ingredients during the initial kneading phase so always be certain to store your flour in a burped & sealed freezer bag.

Yeast: Use active dry yeast for all your standard-rise bread recipes and rapid-rise dry yeast for all your fast-bake bread recipes. Fast-Bake aka Ultra-Bake aka Rapid-Bake aka Express-Bake is an option available on select models. Always refrigerate your yeast with a close eye on the expiration date. When using grocery-bought bread mixes always substitute the yeast packet provided with fresh active dry yeast. Tip: A packet (or "sachet") of active dry yeast contains 2-1/4 teaspoons.

Baking Surface Prep: Spray, not wipe or smear, the inside of your loaf pan generously with cooking oil before adding the ingredients.

Water: Use only drinking or filtered water, never tap, boiled or distilled.

Ingredient Temperatures: All ingredients should be at room temperature before pressing Start. Specifically 70 to 80 degrees F, 21 to 87 degrees C. Add liquids, oils, salts, sugars and seasonings first, next the flour, and last the yeast.

Delayed Start: Flour floats on the surface of the water until the initial kneading phase begins. That is why many breadmakers have a programmable start-delay timer. You can add the ingredients tonight and wake up in the morning to the aroma of fresh-baked bread.

Shelf Life: Refrigeration and/or freezing finished loaves is not recommended. For best results store them in a breadbox. Tip: Adding 1-2 tsps of lemon juice to any bread or dough recipe will double the shelf life of your bread.

Measuring: Water MUST be measured using a clear liquid measuring cup. Dry ingredients MUST be measured using standard measuring cups. All measurements, either spoons or cups, MUST be leveled.

Slicing The Loaf: Electric carving knives work best, especially when using a slicing guide. Be certain to wait until the loaf is cool to the touch before slicing.

That is a difficult problem. One thing you might try to get a better rise in your machine is to cut the salt in your recipe by one half. It's healthier that way too. Please let me know the result.

due to the general acidic properties of these ingredients, the living organisms in yeast may be partially killed off in these recipes. To increase the rise of these breads using a small amount of warm water to activate your yeast (place the yeast in a small dish and add a tablespoon or more of warm, not hot water), until it's a little foamy, helps. If the directions call for the ingredients to be added at a later time then I would follow those instructions, if not, and you're feeling a little adventurous, try adding those ingredients near the end of the 'resting' cycle of the bread maker, this allows the dough to rise before the yeast is submitted to the more acidic ingredients, and you would be adding them before baking again. If your bread maker does not mix again after the resting period this will not work though.
Yeast are little organisms that when revitalized, excrete gases into the dough, giving it little pockets of air, that when baked expand and allows for more even cooking and those little bubbles in your bread that make it fluffy and more tasty. Higher quality east are typically more resistant to acids, and the older the yeast is the lower the gaseous production is.

Ingredient Information

• Flour– Use flour that is marked “bread flour” or “better for bread”. (Thesewill usually be labeled as having more gluten than regular flour.)
• Dry Skim Milk – This enhances the flavor and adds to the nutrition of the bread.
• Butter – Butter adds a rich flavor to the bread and makes it soft.
• DryYeast – Yeast is necessary for causing the dough to rise. Select readyto use yeast which needs no preliminary fermentation. Use only activedry yeast. Don’t use 50% faster dry yeast.
• Sugar – Sugar speeds up the dough rising process, adds flavor, and makes the bread soft and the crust brown.
• Salt – Salt controls the activity of the yeast and makes the dough firm.
• Water– Gluten is formed when flour is mixed with water. This allows thedough to rise by retaining air. The amount of water and its temperatureare very important. Usually, the water temperature should be between 68F/20 C and 77 F/25 C. When the room temperature is over 82 F/ 26C, usecold water (about 41 F/5 C). When the room temperature is under 50 F/10C, use lukewarm water (about 100 F/38 C).
