Frigidaire Washer Code E75 – Troubleshooting Guide

Reading and understanding the error codes on your Frigidaire washer can be quite challenging, especially if you don’t have the user manual nearby. Not to worry, though! If you’re experiencing the E75 error code, this guide will have everything you need to know.

The E75 error code on a Frigidaire washer means that the water temperature sensor circuit has failed. The most likely trigger behind this error code is a failed Negative Temperature Coefficient (NTC) Thermistor (a type of temperature sensor), or a faulty electronic control board. Replacing the problematic part will resolve the issue, allowing you to clear the code.

In the following sections, we’ll dive deeper into the possible causes for this error code and the solutions you can use to resolve them.

On a Frigidaire washing machine, the E75 error code means that the water temperature sensor circuit has failed. The water temperature sensor that this code refers to is the NTC Thermistor, which is a part of the water inlet valve assembly.

The Negative Temperature Coefficient (NTC) Thermistor is a temperature sensor that’s built into the water inlet valve assembly. As the name suggests, this sensor is designed to measure the temperature of the incoming water flow into the washer.

As the NTC Thermistor detects the water temperature, it’ll communicate that information to the electronic control board. From there, the washer can then decide whether or not the water is at the correct temperature based on the wash program you’ve selected.

For example, if the water isn’t hot enough, the washer will then turn on its heating element to raise the temperature as needed.

The most likely triggers for the E75 error code are a failed temperature sensor and a faulty electronic control board. Unfortunately, neither of these parts can be repaired. So, whichever one is causing the E57 error code to appear must be replaced entirely.

Let’s take a closer look at each part and the purpose they serve your Frigidaire washing machine.

Failed Temperature Sensor (At The Water Inlet Valve Assembly)

What it is: The temperature sensor located in the water inlet valve assembly is the Negative Temperature Coefficient (NTC) Thermistor. This sensor is typically made of ceramic material. That material helps the sensor to continuously measure the temperature of the water that flows into your washing machine.

The NTC Thermistor measures temperature with the help of electrical resistance. As the temperature increases at the sensor, its resistance decreases. As a result, it sends a stronger signal to the washer’s electronic control board.

On the other hand, when the NTC Thermistor detects a lower temperature, its resistance will increase.

In both cases, the electronic control board on your Frigidaire washer will interpret the signals and understand the exact water temperature.

How it fails: The NTC Thermistor can fail due to an internal fault, heat damage, or excessive wear.

For example, the resistor element and lead material inside the NTC Thermistor might have physically separated from each other. When that happens, the sensor can no longer react to heat like it’s designed to.

Besides that, excessive heat can also cause damage to the sensor as well. Remember: the sensor’s materials were chosen because they are sensitive to heat and can provide an accurate temperature reading. 

However, repeated exposure to excessive heat can damage the sensor and prevent it from working correctly.

Lastly, excessive wear could also be the culprit here. That’s especially true if your Frigidaire washer has been in use for many years. Simply put, the sensor stops working correctly when it’s been used for far too long.

How to fix it: In this case, the temperature sensor must be replaced. Unfortunately, the temperature sensor cannot be replaced on its own like most other components. That’s because it’s built into the water inlet valve assembly. As such, you’ll have to replace the entire assembly to fix this issue.

The water inlet valve assembly is located inside your washer towards the rear of the frame. You can identify it quickly as it’s the only washer component attached to the incoming water supply hose.

Firstly, remove the washer’s top or back panel to access the water inlet valve assembly. From there, remove all hoses attached to it and remove its electrical wiring.

Once there’s nothing connected to the assembly, you can unthread the screws that mount it to your washer’s frame. Then, finally, remove that assembly and mount the new one in its place.

Lastly, work your way backwards: replace the electrical connectors and wire hoses, and replace the panels you removed earlier.
