The F08 error on your Hotpoint Washing means the heating circuit has failed or the heater relay is stuck. This indicates a problem with water heating components, preventing your machine from reaching the correct temperature for the wash cycle.

Error code F08
Meaning Heating circuit fault or heater relay stuck on main control board
Severity Medium — Machine may run cold cycles but cannot heat water properly
Time to fix 30–90 minutes
Tools needed Multimeter, screwdrivers (Phillips and flat-head), pliers, socket wrench set

What the F08 error means

The F08 error code indicates a malfunction in your Hotpoint washing machine’s heating system. This error typically appears when the control board detects either a faulty heating element, a stuck heater relay, or wiring issues in the heating circuit. When this error occurs, the machine cannot properly heat water to the temperature required for the selected wash program, which compromises cleaning performance and may prevent the cycle from completing.

Common causes

  • Defective heating element with open circuit or short to ground
  • Stuck or faulty heater relay on the main control board
  • Damaged or corroded wiring connections between the control board and heating element
  • Faulty NTC thermistor (temperature sensor) sending incorrect readings
  • Main control board failure affecting the heating circuit management
  • Water level sensor malfunction preventing heating activation for safety reasons

How to fix the F08 error

  1. Unplug the machine and access the heating element — Disconnect power from the outlet and turn off water supply. Remove the back or front panel (model-dependent) to access the heating element located at the bottom of the tub. Check all wire connections to the heating element for corrosion, burns, or loose terminals and repair as needed.
  2. Test the heating element with a multimeter — Disconnect the wires from the heating element terminals. Set your multimeter to resistance (ohms) mode and test across the two element terminals. A working element should read between 20-30 ohms. If you get infinite resistance (open circuit) or zero ohms (short circuit), the element is faulty and needs replacement. Also test from each terminal to the metal casing—this should show infinite resistance; any continuity indicates a short to ground.
  3. Inspect and test the NTC thermistor — The thermistor is usually located near or attached to the heating element. Disconnect its wiring connector and test resistance with a multimeter at room temperature (approximately 68°F). It should read around 10,000-12,000 ohms. Values far outside this range indicate a faulty sensor that needs replacement. Check the wiring harness for damage as well.
  4. Check the heater relay on the control board — Access the main control board (usually behind the control panel). Visually inspect for burnt components, particularly around the heater relay. If you have electronics experience, you can test the relay operation, but control board issues typically require professional diagnosis or board replacement. Look for signs of overheating, discoloration, or damaged relay contacts.
  5. Examine all wiring in the heating circuit — Trace all wires from the control board to the heating element, checking for damaged insulation, pinched wires, or corroded connectors. Pay special attention to wires that may rub against sharp metal edges or moving parts. Repair or replace any damaged wiring with appropriate heat-resistant wire rated for appliance use.
  6. Replace the faulty component and test — Install the new heating element (typically $25-$60), thermistor (typically $15-$35), or control board (typically $150-$300) as identified during testing. Ensure all connections are secure and properly insulated. Reassemble the machine, restore power and water, and run a hot water cycle to verify the error is cleared and water heats properly.

FAQ

Can I still use my Hotpoint washing machine with the F08 error code?
You can run cold water cycles, but the machine cannot heat water with this error present. Hot and warm wash cycles will either fail to complete or wash in cold water only, significantly reducing cleaning effectiveness for heavily soiled items, sanitization cycles, and stain removal. It’s best to repair the issue promptly to restore full functionality.

How much does it cost to fix an F08 error on a Hotpoint washer?
DIY repairs typically cost $25-$60 for a heating element, $15-$35 for a thermistor, or $150-$300 for a control board, plus your time. Professional repair service ranges from $200-$450 depending on the required part and labor rates in your area. The heating element is the most common culprit and relatively affordable to replace yourself with basic tools.

How can I prevent the F08 error from happening again?
Use the appropriate amount of high-efficiency (HE) detergent to prevent excessive suds and residue buildup on heating components. Avoid overloading the machine, which can stress electrical components. Periodically run a maintenance wash with hot water and a washing machine cleaner to remove mineral deposits from the heating element. Ensure proper grounding and stable electrical supply to protect the control board from voltage spikes.
