How to Fix Error Htt — Step by Step

  1. 1

    Quick Reset and Check

    Before starting any repairs, try resetting the dishwasher by turning it off and on. Check the power cord and ensure it's securely plugged in. If the issue persists, proceed to the next step.

    💡 Pro Tip: Make sure the dishwasher is properly installed and levelled to prevent any issues.

  2. 2

    Check the Heating Element

    The heating element is responsible for warming the water during the wash cycle. To check it, locate the heating element at the bottom of the dishwasher tub. Use a multimeter to test for continuity. A reading of around 10-20 ohms is normal. If the reading is significantly different or shows no continuity, the heating element may be faulty.

    💡 Pro Tip: Be careful when handling electrical components to avoid shock or injury.

  3. 3

    Inspect the Thermistor

    The thermistor monitors the water temperature and sends signals to the control board. Check the thermistor for any signs of damage or corrosion. Use a multimeter to test its resistance. A normal reading is around 10-20 kilohms at room temperature. If the reading is abnormal, consider replacing the thermistor.

    💡 Pro Tip: Make sure to clean the thermistor and its surroundings to ensure accurate readings.

  4. 4

    Check the Control Board

    The control board regulates the dishwasher's functions, including the heating element. If the control board is faulty, it may not send the proper signals to the heating element. Check the control board for any signs of damage or burn marks. If you suspect a control board issue, consider consulting a professional.

    💡 Pro Tip: Avoid touching any electrical components to prevent shock or injury.

  5. 5

    Verify the Wiring and Connections

    Inspect the wiring and connections between the heating element, thermistor, and control board. Make sure all connections are secure and not damaged. Check for any signs of wear or corrosion on the wires.

    💡 Pro Tip: Use a wire stripper to remove any insulation and inspect the wires.

When to Call a Professional

If you've checked all the above steps and the issue persists, or if you're not comfortable with DIY repairs, consider hiring a professional. Additionally, if you notice any signs of electrical shock or water damage, shut off the power and water supply immediately and call a pro.

Diagnostic Flowchart

Follow this visual guide to systematically diagnose Error Htt:

If you’re seeing the GE Dishwasher error code Htt, it means your appliance is experiencing a heater timeout issue. This error can cause your dishwasher to malfunction and not complete the wash cycle, leaving you with dirty dishes and a puzzling error message. The Htt error code typically appears during the wash cycle when the dishwasher is unable to heat the water properly.

What GE Dishwasher Error Htt Actually Means

The GE Dishwasher error code Htt indicates that the water in the dishwasher is not heating properly. This issue is usually related to the heating element or the thermistor that monitors the water temperature. When the dishwasher is unable to heat the water to the required temperature within a certain timeframe, it throws the Htt error code. The heating element is responsible for warming the water during the wash cycle, while the thermistor ensures that the water temperature is within the optimal range.

The Htt error code is often caused by a faulty heating element or a malfunctioning thermistor. However, it can also be triggered by issues with the control board, wiring, or connections. In some cases, a simple reset or cleaning of the dishwasher’s filters may resolve the issue.

Quick Checks Before You Repair

Before calling a professional or diving into complex repairs, try these quick diagnostic checks:

  • Check the power cord and ensure it’s properly plugged into the outlet.
  • Verify that the dishwasher’s circuit breaker hasn’t tripped.
  • Check the water supply and ensure it’s turned on.
  • Run a cleaning cycle with a dishwasher cleaner to remove any debris or grease buildup.

To perform a power cycle, which is specific to GE dishwashers:

  • Press the “Cancel” or “Reset” button on your GE dishwasher.
  • Unplug the dishwasher from the power outlet.
  • Wait for 30 seconds to allow any residual power to drain.
  • Plug the dishwasher back in and restart it.
