Symptoms
- No response when pressing power or pulse button
- Motor doesn't hum or move at all
- Bowl and lid appear seated but nothing happens
- Worked fine on the last use
Likely causes
- CommonLid not locked into the bowl correctlyMost processors have a safety switch that requires the lid to twist-lock fully before the motor will run.
- CommonBowl not seated or locked on the baseSimilarly, the bowl itself often must click into a locked position.
- PossibleFeed tube pusher not inserted (on some models)A few models require the pusher to be in place to complete a safety circuit.
- CommonPower outlet or cord issueWorth ruling out before assuming the unit failed.
- Less commonFailed motor or internal switchLess common, but possible after years of heavy use.
What to do
- Remove the lid and bowl completely, then reassemble carefully, making sure the bowl clicks into the base and the lid twists and locks fully onto the bowl.
- Check for a small feed tube pusher that may need to be inserted for the safety circuit to complete, depending on your model.
- Plug into a different outlet to rule out a power supply issue.
- Inspect the interlock tabs on the lid and bowl rim for cracks or wear that could prevent a full, safety-switch-triggering seat.
- Clean any food residue from the locking areas that might be preventing a full seat.
- If it still won't turn on with everything properly assembled and a working outlet, the internal switch or motor has likely failed and typically isn't cost-effective to repair on standard models.
When to call a pro
For most consumer food processors, replacement is more practical than repair if the safety switches and power are confirmed fine.

Generally low risk
