Check safely first
- Switch the dishwasher off at the power.
- Remove the bottom rack, then the filter, and rinse it under running water.
- Look around the sump for trapped objects such as glass fragments or fruit stones, and handle them carefully.
- Check the drain hose behind the machine for kinks.
- Run a short cycle to see whether the water drains.
Do not put your hand near the pump; if these steps do not work, call the technician.
