Dishwasher shows E7 and may stop mid-cycle; water may be present but not heating correctly or cycle times are erratic.

Safety first: Unplug the dishwasher before accessing internal components.

• Locate NTC sensor: On many CDA dishwashers, the NTC is clipped into the sump or integrated into the heater assembly.
• Visual inspection: Check the sensor body and connector for signs of corrosion, water ingress, or broken wires.
• Check connection: Reseat the connector to ensure a firm contact.
• Measure resistance (for trained persons): With a multimeter, measure the NTC resistance at room temperature. Typical values are between 10–60 kΩ depending on design. A reading of 0 Ω (short) or infinite (open) indicates a faulty sensor.
• Replace sensor: If readings are abnormal, fit a CDA-compatible NTC sensor. Ensure the O-ring or gasket is correctly seated to prevent leaks.
• If sensor is OK: The issue may lie with the control board. Further electronic diagnosis or board replacement may be required by a professional.
