How to fix it
- Open the door and sprinkle a few tablespoons of table salt or vegetable oil onto the suds to break them.
- Manually scoop out as much suds and water as possible.
- Run a Rinse-Only cycle (no detergent) once or twice to flush all soap from the system.
- Going forward, use only detergent labeled for automatic dishwashers and dose per the soft/hard water guidance.
- Wipe up any spilled rinse aid around the dispenser.
Why it happens
Typical signs: F6E3 on display · Visible suds in tub · Pump runs but no spray pressure
- Dish soap used instead of dishwasher detergent Hand dish soap creates massive suds that lock the pump.
- Too much detergent in soft water Soft water needs much less detergent.
- Spilled rinse aid Overfilled rinse aid dispenser leaking into the tub.
