What E:06 means on a Viking dishwasher

The E:06 error code on a Viking dishwasher indicates a fault with the NTC (Negative Temperature Coefficient) thermistor, which is the sensor responsible for monitoring wash water temperature. The control board reads resistance values from this sensor continuously during operation. When the measured resistance falls outside the expected specified range, or when the circuit reads as fully open (no continuity) or fully shorted (zero resistance), the board logs the E:06 fault. Because the thermistor provides the temperature feedback the dishwasher needs to regulate heating, the software is programmed to skip the heating step entirely when this fault is active and continue the cycle without it.

The NTC thermistor is a passive resistive component whose resistance changes predictably with temperature. An open circuit reading typically indicates a broken wire, a failed thermistor, or a disconnected connector. A short circuit reading points to damaged wiring where conductors are contacting each other, or an internally failed sensor. Resistance values outside the specified range can also result from a thermistor that is degrading but not yet completely failed, or from poor connector contact introducing erratic readings.

Diagnosing E:06 requires inspecting the NTC sensor itself, the cable harness running between the sensor and the control board, and the control electronics. Corroded or loose connector pins in the harness are a common source of intermittent or out-of-range readings. If the harness and connectors check out, the thermistor should be tested directly with a multimeter to confirm its resistance is within spec. If both components test correctly, a faulty control board may be misreading the signal.

Common causes of E:06

  1. 01

    Failed NTC thermistor

    Part replacement

    The thermistor itself has failed internally, producing an open circuit, short circuit, or out-of-range resistance reading. Testing the sensor with a multimeter and comparing the reading to the specified resistance range will confirm this.

  2. 02

    Damaged or disconnected wiring harness

    Wiring / connection

    The cable harness connecting the NTC thermistor to the control board may have a broken wire, a loose connector, or corrosion on the terminals. Visually inspect the harness and connectors and use a multimeter to check for continuity along each wire.

  3. 03

    Corroded or loose connector pins

    Wiring / connection

    Connector pins at either the thermistor end or the control board end can corrode or back out, causing intermittent or erratic resistance readings. Inspect both connectors carefully and reseat or clean them as needed.

  4. 04

    Shorted wiring in the harness

    Part replacement

    Two or more conductors in the harness may be contacting each other due to chafed insulation, causing the board to read a short circuit on the NTC circuit. Inspect the full length of the harness for worn or pinched insulation.

  5. 05

    Faulty control board

    Part replacement

    If the NTC thermistor and the entire harness test correctly, the control board itself may be misinterpreting the sensor signal. This is the least common cause and should only be considered after ruling out the sensor and wiring.

Frequently asked questions about E:06

What does E:06 mean on a Viking dishwasher?
E:06 indicates an NTC thermistor fault, meaning the dishwasher's temperature sensor is producing a resistance reading that is outside the expected range, or is reading as a fully open or shorted circuit. The NTC thermistor is the sensor the dishwasher uses to monitor water temperature during the wash cycle. When this fault is detected, the control software skips the heating step and completes the cycle without heating the water.
Will resetting the dishwasher clear the E:06 error?
A reset may temporarily clear the E:06 code, but the fault will return if the underlying problem with the NTC thermistor, wiring harness, or control board has not been repaired. Because the dishwasher skips the heating step when this fault is active, the unit will continue to underperform until the root cause is addressed. A reset is useful for confirming whether the fault is intermittent, but it is not a fix.
Is it safe to keep using the dishwasher with an E:06 error?
The dishwasher will continue to run cycles with an E:06 fault active, so there is no immediate safety hazard in most cases. However, because the heating step is skipped, the water will not reach the temperatures needed for effective cleaning and sanitation. Running the dishwasher in this condition means dishes are not being properly sanitized, which is a hygiene concern, particularly for households with young children or immunocompromised individuals.
How much does it cost to fix an E:06 error on a Viking dishwasher?
Repair costs depend on the failed component. Replacing the NTC thermistor is typically the least expensive fix, with parts generally ranging from around $15 to $60 and labor adding to that total. A wiring harness repair or replacement can range from $50 to $150 or more depending on the extent of the damage. If the control board is at fault, parts alone can range from $150 to $400 or higher, plus labor, making board replacement the most costly scenario.
How do I diagnose an E:06 error on a Viking dishwasher?
Start by inspecting the NTC thermistor and the cable harness connecting it to the control board. Look for damaged wiring, corrosion on connector pins, or loose connections. Use a multimeter to test the thermistor's resistance and check for continuity through the harness. If the sensor resistance is out of range or the harness has a break or short, those components should be repaired or replaced. If both test correctly, the control board may be the source of the fault.
