MDT24P3CST E6 Error Code | Midea Dishwasher Fault Guide
Error E6 on Midea MDT24P3CST: NTC temperature sensor open circuit — temperature sensor has lost continuity and. Follow the troubleshooting steps below to diagnose and fix this Dishwasher issue.
What Is the E6 Error Code on the Midea MDT24P3CST? The E6 fault on the Midea MDT24P3CST — a 24-inch Top Control Built-In Dishwasher with 3-Stage Total Drying, third rack, 45 dBA quiet operation, and Wi-Fi connectivity — means: NTC temperature sensor open circuit — temperature sensor has lost continuity and cannot provide temperature readings. The E6 error code on Midea dishwashers indicates the NTC (Negative Temperature Coefficient) thermistor has an open circuit condition — the sensor’s internal resistance element has broken, disconnected, or its wiring has failed. The NTC sensor continuously monitors wash water temperature and provides feedback to the control board to regulate heating. Without valid temperature data, the control board enters a fault state and prevents the dishwasher from operating, as there is no way to ensure proper wash temperatures or prevent overheating. > Severity: Medium — This error requires professional service. ---

Section titled “Symptoms of the E6 Error When the E6 error code appears on your Midea MDT24P3CST: - E6 displayed on the control panel at the start of or during a cycle”- Dishwasher refuses to begin heating phase
- Cycle aborts early with E6 code
- No response after resetting — E6 returns immediately
- Dishwasher fills with water but then stops with E6 before washing ---
Common Causes The E6 error on the Midea MDT24P3CST is typically caused by: - NTC sensor element has broken internally (open circuit) from heat cycling or age
Section titled “Common Causes The E6 error on the Midea MDT24P3CST is typically caused by: - NTC sensor element has broken internally (open circuit) from heat cycling or age”- Sensor wiring harness connector has come loose from the control board
- Sensor wiring insulation damaged by the heating element causing an open break
- Corrosion on sensor connector terminals preventing electrical contact
- Sensor has been physically damaged from impact or debris inside the tub ---
Step-by-Step Troubleshooting
Section titled “Step-by-Step Troubleshooting”| Step | Action | What to Do | Expected Result |
|---|---|---|---|
| 1 | Power cycle the dishwasher | Turn off the dishwasher at the circuit breaker or unplug it for 5 minutes. This resets the control board memory. Restore power and attempt to start a new cycle. If E6 was caused by a momentary wiring fault, it may clear after a power reset. | Dishwasher starts cycle without E6 reappearing |
| 2 | Locate and inspect the NTC sensor | Disconnect power to the dishwasher. The NTC sensor is typically a small cylindrical probe mounted in the sump area at the bottom of the tub or near the heating element. Locate its wiring harness and check that the connector is fully seated at both the sensor end and the control board end. | NTC sensor connector is fully seated with no corrosion |
| 3 | Measure NTC sensor resistance | With the dishwasher disconnected from power, use a multimeter set to ohms mode. Measure resistance across the two NTC sensor terminals. At room temperature (77°F/25°C) the sensor should read approximately 10 kΩ. An OL (open line) reading confirms the sensor element is broken and must be replaced. | Sensor reads approximately 10 kΩ at room temperature (77°F/25°C) |
| 4 | Inspect sensor wiring for damage | Trace the sensor wiring from the probe to the control board connector. Look for any cut, burnt, or pinched wires. Even a hairline crack in the insulation can cause an intermittent open circuit that triggers E6. | Sensor wiring is intact with no visible damage |
| 5 | Replace the NTC sensor | If the sensor reads OL or has damaged wiring, replace the NTC sensor. Contact Midea support at 1-877-468-4734 for the correct part number for your model, or consult an authorized Midea service center for replacement. | New NTC sensor installed and dishwasher completes cycle normally |
Frequently Asked Questions
Section titled “Frequently Asked Questions”What does E6 mean on a Midea dishwasher?
Section titled “What does E6 mean on a Midea dishwasher?”E6 means the NTC temperature sensor circuit is open — the sensor has broken internally, disconnected from its wiring, or has a damaged wiring harness. The control board cannot receive temperature readings so it stops the cycle with E6 as a safety precaution.
Can I fix E6 on my Midea dishwasher myself?
Section titled “Can I fix E6 on my Midea dishwasher myself?”Checking and reseating the sensor connector is a DIY step. However, if the sensor itself is broken (confirmed by a multimeter reading of OL/infinity), replacing the NTC sensor requires accessing internal components and is best handled by a qualified technician to avoid voiding the warranty.
What is an NTC sensor in a dishwasher?
Section titled “What is an NTC sensor in a dishwasher?”NTC stands for Negative Temperature Coefficient. An NTC sensor is a temperature-sensitive resistor whose resistance decreases as temperature increases. In a dishwasher, it monitors wash water temperature and sends real-time feedback to the control board to accurately regulate the heating element.
Is E6 the same as E7 on a Midea dishwasher?
Section titled “Is E6 the same as E7 on a Midea dishwasher?”No. E6 means the NTC sensor circuit is open (infinite resistance — sensor is broken or disconnected). E7 means the sensor circuit is shorted (resistance is abnormally low). Both codes indicate NTC sensor problems but opposite electrical failure modes. A multimeter test distinguishes them.
How do I test the NTC sensor on my Midea dishwasher?
Section titled “How do I test the NTC sensor on my Midea dishwasher?”Unplug the dishwasher. Locate the NTC sensor in the sump area and disconnect its 2-wire harness. Set a multimeter to ohms and measure resistance across the two sensor terminals. A healthy sensor reads approximately 10 kΩ at room temperature (77°F/25°C). OL (infinity) indicates E6 — the sensor element is broken. ---
Is it safe to keep using my Midea MDT24P3CST with error E6?
Section titled “Is it safe to keep using my Midea MDT24P3CST with error E6?”If error E6 does not indicate an immediate safety hazard such as a gas leak, electrical short, or water flooding, you can continue limited use while monitoring the appliance. However, running the Dishwasher with an active error code increases the risk of further damage. Address the underlying issue as soon as possible. For high-severity errors, disconnect the appliance and contact a qualified technician.
How much does it cost to fix error E6 on a Midea MDT24P3CST?
Section titled “How much does it cost to fix error E6 on a Midea MDT24P3CST?”Repair costs for error E6 on the Midea MDT24P3CST Dishwasher depend on the root cause.
