The error code information provided in this article may not apply to your specific appliance model. The disassembly information is based on models starting with DW7933. While we strive to offer helpful advice for DIY appliance repairs, variations in models and configurations can lead to differences in troubleshooting steps, error codes and part replacements. For the most accurate guidance, we strongly recommend consulting the technical sheet for your specific appliance model.
What the error code means
This error code indicates that the dishwasher is not able to detect the proper water level during the wash cycle. The water level sensor is responsible for monitoring the water level inside the dishwasher tub. When the dishwasher is filling with water, the water level sensor should be activated to confirm that the correct water level has been reached. If the water level sensor is not activated after the water supply fill is complete, the dishwasher will attempt to drain and refill the water. If the high-level sensor is still not detected after the refill, the 9E error code is triggered.
Additionally, the 9E error can occur if the water level sensor detects a low water level for more than 5 seconds during the wash cycle. In summary, the 9E error indicates an issue with the water level sensor’s ability to properly detect the water level inside the dishwasher.
Safety precautions
When working on any appliance, remember to keep safety first. Here are some tips to keep in mind:
- Always power off and unplug your appliance or switch off the circuit breaker before attempting any maintenance or replacement work. This keeps you safe by preventing any risk of injury from electric shock.
- Wear insulated work gloves to protect your hands from sharp metal parts, pinching hazards and debris.
- Take your time and don’t rush while working to prevent accidents and personal injuries.
- Work in a well-lit area so you can clearly see and access the interior parts.
- Clear your workspace of clutter and other obstacles. Keep children and pets away from the work area.
- Never work on internal parts with bare wet hands. Make sure the work area is completely dry.
- Check your user manual to see if there are specific installation or safety instructions for your part or appliance.
- Be gentle when handling or removing parts. Excessive force might damage the appliance or cause injury.
- Wear safety glasses when working with chemicals, dust or cleaning large debris to prevent injury.
- If the appliance has recently been used, give it plenty of time for any heating parts to cool down before working on it.
- Take pictures or make a note of wiring terminals or other connections before disconnecting to prevent any problems with reassembly.
- When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
- Turn off the water supply at the outlet before beginning repairs to any appliance parts that hold water. Have towels ready for any residual water in the system when removing parts.
