Original Miele temperature sensor for dryer, washing machine and dishwasher 7017320

The original Miele NTC temperature sensor 7017320 is a critical spare part used in tumble dryers, washing machines and dishwashers. The sensor is responsible for monitoring and regulating the water temperature throughout the entire operating cycle. Its failure results in poor washing results, incomplete drying, or fault codes. The original part ensures accurate measurement and compliance with Miele control protocols.

In the experience of our technicians, over 60% of temperature problems in Miele appliances – whether it’s partial drying, washing at the wrong temperature, or a recurring fault code – are resolved by replacing this sensor alone. It’s one of the most sought-after spare parts for the T1, W1 and G series.

Just before ordering – NTC sensors look similar but are not identical. A non-genuine part may give incorrect readings and cause damage to the heating motor. Click the “Check Model Compatibility” button at the top of the page to instantly verify that the part fits your device.

What causes temperature errors in Miele appliances?

A faulty NTC sensor leads to three main symptoms: the appliance does not reach the required temperature, overheats, or displays an error code and stops in the middle of the cycle. Miele's electronic control relies on accurate real-time readings. A sensor that deviates by more than 2°C causes the system to operate on incorrect data.

The most common signs of sensor failure:

✅ The laundry comes out cold despite selecting a hot program

✅ The dryer does not dry completely and interrupts the cycle early.

✅ The dishwasher displays an error code and stops before the rinse phase

✅ The device operates under pressure without finishing the cycle.

⚠️ When our technicians arrive at a heating fault, the first thing they check is always the sensor. In most cases, replacing it is simple and prevents another expensive service call.

What is the difference between an original and a replacement sensor?

The original Miele 7017320 sensor is manufactured to the same specifications as the production line. Its measurement deviation is less than 1°C throughout the entire temperature range. Non-original parts often work in a narrow range and deteriorate relatively quickly. When the control receives inaccurate readings, it turns on the heating element for a longer time – and over time this shortens the life of the element.

🔧 How do you replace a temperature sensor on a Miele?

Replacing an NTC sensor is a technical operation that requires opening the device body and disconnecting electrical components. Average work time: 20-40 minutes for an experienced technician. Required: Phillips screwdriver, flat screwdriver, and a multimeter to test the sensor before and after.

⚠️ Before any action – completely disconnect the device from the power supply.

1. Locating the sensor – The E-Nr sticker is located on the appliance door (dryer and washing machine) or on the side wall (dishwasher).
2. Opening the panel – depending on the type of device, open the back or bottom.
3. Disconnecting the connector – gently release the locking latch
4. Sensor replacement – ​​hand-tighten, do not overtighten
5. Reconnect the connector and test cycle.

⚠️ It is recommended that the replacement be performed by a qualified technician - any action on the device's body may damage additional components if performed without experience.

💡 Tip from the experts

Before replacing – test the sensor with a multimeter. At room temperature (25°C) the resistance of a good sensor is between 8,000 and 12,000 ohms. A reading outside this range confirms failure. Our technicians always perform this test – it saves unnecessary replacement. A sensor that shows infinite resistance (OL) is a complete failure – no further testing is required.

❓ Frequently Asked Questions

What is the fault code that appears when the sensor fails?

Common fault codes for temperature sensor failure on Miele are F11, F53 and Tech 53, depending on the model. This code appears when the control detects a reading outside the expected range. Before replacing, it is recommended to perform a multimeter test to confirm the failure.

Is the same sensor suitable for all three devices?

Yes. The 7017320 sensor is a standard original part that Miele uses in dryers, washing machines and dishwashers. The reason is that the monitoring mechanism works on the same principle in all three appliances. Please check the E-Nr for compatibility with the specific series.

Is it possible to check the sensor before replacing it?

Absolutely. With a simple multimeter set to ohms, measure the resistance between two pins. At room temperature, the normal value is 8,000-12,000 ohms. A value that is too high, too low, or infinite – the sensor has failed and should be replaced.
