4. Installation Guide
This section provides general steps for replacing the drive belt. Specific disassembly procedures may vary slightly between bread maker models. Refer to your bread maker's original service manual if available.
4.1. Tools Required
- Screwdriver set (Phillips and/or Torx, depending on model)
- Pliers (optional, for stubborn connections)
- Clean cloth
4.2. Step-by-Step Installation
Disconnect Power: Ensure the bread maker is unplugged from the electrical outlet before starting any work.
Access the Mechanism: Carefully turn the bread maker upside down. Locate and remove the screws securing the bottom panel. Gently remove the bottom panel to expose the internal components, including the motor and drive shaft.

Remove Old Belt: Identify the old drive belt connecting the motor pulley to the kneading paddle shaft pulley. Carefully remove the old belt. It may be worn, cracked, or broken.
Clean Area: Use a clean cloth to wipe away any bread crumbs, flour, or debris from the pulleys and surrounding area. Ensure the pulleys are free to rotate.
Install New Belt: Place the new Moulinex Drive Belt 90S3M537 onto the smaller motor pulley first. Then, carefully stretch and guide the belt onto the larger kneading paddle shaft pulley. Ensure the belt is seated correctly in the grooves of both pulleys.
Test Rotation: Manually rotate the kneading paddle shaft to ensure the belt moves smoothly and without obstruction. The motor pulley should also turn.
Reassemble: Carefully replace the bottom panel, ensuring all wires are clear and not pinched. Secure the panel with the screws removed earlier. Do not overtighten.
Final Check: Plug the bread maker back into the power outlet and perform a short test cycle (e.g., kneading cycle) to confirm proper operation of the new drive belt.
5. Maintenance
To ensure the longevity of your new drive belt and the optimal performance of your bread maker:
- Regularly clean the interior of your bread maker, especially around the kneading shaft, to prevent debris from interfering with the belt.
- Avoid overloading the bread maker, as excessive strain can prematurely wear out the drive belt.
- If you notice unusual noises or inconsistent kneading, inspect the belt for signs of wear or damage.
6. Troubleshooting Common Issues
| Symptom | Possible Cause | Solution |
|---|---|---|
| Kneading paddle not turning | Belt broken or slipped off | Inspect and replace/reposition belt |
| Grinding noise during kneading | Belt misaligned or worn | Check belt alignment; replace if worn |
| Motor runs but paddle doesn't move | Belt completely broken | Replace drive belt |
