Symptoms
- Trigger doesn't respond at all
- Motor runs briefly then stops
- Cordless model has no power despite charging
- Blends slower than usual before stopping
Likely causes
- CommonSafety lock or trigger not engaged correctlyMany models require holding a separate lock button while pressing the trigger.
- CommonCordless battery depleted or failingBatteries lose capacity over time and eventually won't hold a usable charge.
- PossibleBlade end not fully attached to the motor bodyA loose connection between the shaft and motor housing can prevent it from powering on.
- PossibleMotor overload from thick contentsBlending very thick mixtures can trigger an automatic shutoff.
- PossibleCord or outlet issue (corded models)Worth ruling out before assuming the motor failed.
What to do
- Check that the blending shaft is fully twisted or clicked onto the motor body, since most models won't run if it's loose.
- If there's a separate safety button, press and hold it while squeezing the trigger.
- For corded models, try a different outlet.
- For cordless models, place it on the charging base and confirm the charging light comes on; let it charge fully before testing again.
- Remove the blade attachment and check for jammed food debris preventing the shaft from turning.
- If it still won't start with a fully attached shaft, full charge, and known-good outlet, the motor has likely failed and replacement is usually more practical than repair.
