MDT24P3CST E3 Error Code | Midea Dishwasher Fault Guide
Error E3 on Midea MDT24P3CST: Heating error — wash water failed to reach the required temperature within the s. Follow the troubleshooting steps below to diagnose and fix this Dishwasher issue.
What Is the E3 Error Code on the Midea MDT24P3CST? The E3 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: Heating error — wash water failed to reach the required temperature within the set time limit. The E3 error code on Midea dishwashers means the water inside the tub did not reach the target wash temperature within the allowed time — approximately 9 minutes of heating. Proper water temperature is critical for effective cleaning and sanitizing. E3 can result from a failed heating element, a faulty NTC temperature sensor giving false low readings, or insufficient water in the tub (since the heater requires a minimum water level to function). This code typically requires professional diagnosis unless the water fill level is the culprit. > Severity: Medium — This error requires professional service. ---

Section titled “Symptoms of the E3 Error When the E3 error code appears on your Midea MDT24P3CST: - E3 displayed on the control panel, typically during the main wash phase”- Dishes come out with grease or food residue despite completing a cycle
- Dishwasher fills with water but cycle halts before wash phase begins
- Steam is not visible inside the dishwasher during hot cycles
- Sanitize or High-Temp wash cycles consistently fail with E3 ---
Common Causes The E3 error on the Midea MDT24P3CST is typically caused by: - Heating element has burned out or developed an open circuit
Section titled “Common Causes The E3 error on the Midea MDT24P3CST is typically caused by: - Heating element has burned out or developed an open circuit”- Thermal safety thermostat has tripped and needs to be reset or replaced
- NTC temperature sensor is faulty and reading temperature as lower than actual
- Insufficient water level in tub meaning heater runs but water is too shallow to heat properly
- Control board relay that powers the heating element has failed ---
Step-by-Step Troubleshooting
Section titled “Step-by-Step Troubleshooting”| Step | Action | What to Do | Expected Result |
|---|---|---|---|
| 1 | Check for insufficient water fill | Before assuming a heater failure, run a short cycle and listen for the fill phase. If the dishwasher fills with very little water before the heater activates, the E1 water inlet issue may be causing E3 indirectly. Ensure E1 is not also present and that water fills to the proper level. | Tub fills with water to the correct level before heating begins |
| 2 | Test the heating element resistance | Disconnect the dishwasher from power. Access the heating element terminals from beneath the dishwasher. Use a multimeter to measure resistance across the element terminals — a working element reads approximately 29 Ω. An OL (infinity) reading indicates the element is burned out. | Heating element reads approximately 29 Ω at room temperature |
| 3 | Check the thermal safety thermostat | Located near the heating element, the thermal safety thermostat is a safety device that cuts power if the element overheats. Measure continuity across the thermostat — it should show continuity (near 0 Ω) when cool. No continuity means it has tripped and may need replacing. | Thermostat shows continuity when cool |
| 4 | Test the NTC temperature sensor | The NTC sensor provides temperature feedback to the control board. Disconnect the sensor connector and measure its resistance. At room temperature (77°F/25°C) it should read approximately 10 kΩ. A significantly different reading indicates a faulty sensor. | NTC sensor reads approximately 10 kΩ at room temperature |
| 5 | Schedule professional service | If the heating element, thermostat, or NTC sensor are confirmed faulty, contact Midea service at 1-877-468-4734 or visit midea.com/us. Replacing these components requires safe access to high-voltage wiring inside the dishwasher. | Authorized technician replaces faulty heating component |
Frequently Asked Questions
Section titled “Frequently Asked Questions”What does E3 mean on a Midea dishwasher?
Section titled “What does E3 mean on a Midea dishwasher?”E3 means the dishwasher water could not reach the required wash temperature within the allowed time (approximately 9 minutes). This indicates a heating system problem — most commonly a failed heating element, a tripped thermal thermostat, or a faulty temperature sensor.
Can a Midea dishwasher run without a working heater?
Section titled “Can a Midea dishwasher run without a working heater?”Some cycles can partially complete without heating, but the Sanitize and High-Temp wash options require the heater and will consistently trigger E3 if it fails. Wash performance also degrades significantly at lower temperatures as grease and stubborn food soils require heat to dissolve.
How do I test the heating element on my Midea dishwasher?
Section titled “How do I test the heating element on my Midea dishwasher?”Unplug the dishwasher from power. Access the heating element terminals at the bottom of the tub or from beneath the machine. Set a multimeter to ohms and measure resistance across the two terminals — approximately 29 Ω is correct. An infinite (OL) reading means the element is burned out and needs replacement.
Will using hot water from the tap fix E3?
Section titled “Will using hot water from the tap fix E3?”Using hot water from the tap (by running the sink hot before starting the dishwasher) can reduce heating demand and may temporarily avoid E3 in marginal cases. However, this does not fix the underlying problem. If the heating element is failed, E3 will persist regardless of incoming water temperature.
How long does a Midea dishwasher heating element last?
Section titled “How long does a Midea dishwasher heating element last?”Heating elements typically last 8-15 years. Their lifespan is shortened by hard water scale buildup (which insulates the element and causes overheating) and frequent use of high-temperature or sanitize cycles. Descaling the dishwasher regularly with citric acid or a dedicated dishwasher cleaner extends heater life. ---
Is it safe to keep using my Midea MDT24P3CST with error E3?
Section titled “Is it safe to keep using my Midea MDT24P3CST with error E3?”If error E3 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 E3 on a Midea MDT24P3CST?
Section titled “How much does it cost to fix error E3 on a Midea MDT24P3CST?”Repair costs for error E3 on the Midea MDT24P3CST Dishwasher depend on the root cause. DIY fixes such as cleaning filters, resetting the unit, or reconnecting loose wires cost nothing beyond basic tools. If a component replacement is needed, parts and labor from a certified technician are the main expenses. Contact a Midea-authorized service provider for an accurate estimate based on your specific situation.
