E8
Whirlpool Washing Machine
Severity: ModerateWhat Does This Error Mean?
The E8 error on a Whirlpool washer indicates a problem with the water temperature sensor or the heating system. The washer cannot confirm that the water has reached the required temperature for the selected cycle. This is especially common on warm and hot wash cycles. You may notice the washer pausing during the fill or wash phase, or clothes not getting properly cleaned.
Affected Models
- Whirlpool Duet WFW9200SQ
- WFW9400SW
- WFW94HEXW
- WFW96HEAW
- Select Whirlpool front-load washers with internal heating
Common Causes
- NTC temperature sensor (thermistor) has failed and is giving incorrect temperature readings
- Heating element has burned out and cannot warm the water
- Wiring to the temperature sensor or heater is loose or damaged
- Incoming water supply temperature is far below normal — cold water supply only
- Control board fault causing incorrect temperature management
How to Fix It
-
Check that both the hot and cold water supply faucets behind the washer are fully open. Cold-only water supply can prevent the washer from reaching required temperatures on heated cycles.
Turn both faucets fully counterclockwise to open them completely. A partially closed hot water valve dramatically reduces wash water temperature.
-
Make sure your home's hot water heater is working and producing hot water. Run the hot water tap at a nearby sink and confirm it gets hot within 30 seconds.
If the water heater is set below 120 degrees Fahrenheit, the washer may not receive water hot enough to satisfy the temperature sensor.
-
Unplug the washer for 60 seconds, plug it back in, and run a cold-water cycle. If E8 does not appear on a cold cycle, the issue is specifically with the heating circuit.
This test confirms whether the problem is temperature-sensing, heating-element, or water supply related.
-
If E8 appears consistently, have a technician test the NTC thermistor. They will measure resistance across the sensor at different temperatures. A failed thermistor reads outside the normal range.
The thermistor on most Whirlpool front-loaders is located near the heating element at the bottom-rear of the drum.
-
If the thermistor tests fine, have the heating element tested. A burned-out element will show as an open circuit on a multimeter. Replace the element if it has failed.
Heating element failure is common on machines used with hard water, as scale deposits reduce its efficiency and eventually cause it to burn out.
When to Call a Professional
The thermistor and heating element require disassembly to access and test. A technician can diagnose and replace these components in one to two hours. A thermistor costs $15 to $30. A heating element costs $30 to $80. Total repair is typically $150 to $300.
Frequently Asked Questions
Does my Whirlpool washer have a built-in heater?
Many Whirlpool front-load washers include an internal heating element for sanitize and allergen cycles. Top-load washers typically rely entirely on the home's hot water supply. Check your manual to confirm whether your model has a built-in heater. Models with a steam or sanitize cycle almost always have one.
Will E8 prevent my clothes from getting clean?
On cold-water cycles, probably not — E8 mainly affects heated wash cycles. However, if the error stops the cycle entirely, clothes will sit in unfinished soapy water. For normal laundry, switching to a cold wash cycle avoids E8 while you arrange a repair.
Can scale buildup cause E8?
Yes. Hard water scale on the heating element acts as an insulator. The element heats up but cannot transfer that heat efficiently to the water. It may overheat and fail, or simply be unable to reach target temperatures. Using a descaling treatment every 3 to 6 months in hard water areas helps prevent this.
