A loaf may rise strongly and then collapse when gas production exceeds the dough’s ability to hold it. Too much liquid, yeast or sugar, insufficient flour strength, or a cycle that is too long for the formula are common possibilities.
What to evaluate
Use the following checks to keep the decision tied to the exact machine, recipe and household rather than generic claims.
- Review total liquid, including eggs, syrups and wet add-ins.
- Check yeast measurement and room temperature.
- Confirm flour type and pan capacity.
- Notice whether the loaf collapsed before or during baking.
A practical workflow
Work from a known baseline and keep enough notes to understand what changed.
- Return to a known baseline formula.
- Reduce only the most likely excess in a small step.
- Use the correct loaf-size setting.
- Allow the cooled loaf to reveal whether the centre is gummy or merely indented.
Common mistakes to avoid
- Adding extra yeast to a loaf that already over-expanded.
- Reducing liquid drastically and creating a dry loaf.
- Ignoring sugary or very warm conditions.
- Using a small-pan recipe setting for a large dough.
A dramatic rise is not always a strong rise; structure matters.
