Possible Causes
Worn motor bearings, Debris in motor fan, Misaligned motor housing, Overheating damage to motor
How to Fix / Troubleshooting
Safety first: Remove the battery. Do not continue to run a noisy motor as it may fail catastrophically.
- Step 1 – Rule out nozzle noise: Run the vacuum with the floor nozzle removed. If the noise disappears, the issue is in the nozzle, not the main motor.
- Step 2 – Listen near motor housing: If noise persists with no attachments, it is likely from the main motor.
- Step 3 – Internal inspection (advanced): Open the main body and inspect the motor assembly. Look for debris near the fan intake and signs of overheating.
- Step 4 – Replace motor assembly: Main motor bearings are not typically serviceable. Replace the entire motor module with a genuine Princess motor assembly.
- Step 5 – Reassemble and test: Ensure all seals and gaskets are correctly fitted to avoid new noises or air leaks.
