What Er:06 means on a Vision washer

Er:06 on a Vision washer indicates a short circuit condition in the NTC (Negative Temperature Coefficient) thermistor circuit. The NTC thermistor is a temperature-sensing resistor responsible for monitoring water temperature during the wash cycle. When the control board detects a short circuit in this circuit, it triggers Er:06 and halts operation to prevent damage from uncontrolled heating or incorrect temperature regulation.

A short circuit in the NTC circuit means the resistance has dropped to near zero, which the control board interprets as an impossibly high temperature reading. This can result from a wiring fault where two conductors in the NTC harness make direct contact, a pinched or damaged cable, or a failed NTC thermistor itself. The thermistor body can fail internally, creating a short between its terminals regardless of actual water temperature.

Diagnosing this fault requires isolating whether the problem lies in the wiring or the thermistor component. Inspecting the cable run from the NTC to the control board for visible damage, pinch points, or melted insulation is the recommended first step. If the wiring is intact, the NTC thermistor should be tested with a multimeter. A shorted NTC will show near-zero resistance rather than the expected resistance value that changes with temperature. Rectifying the cable fault or replacing the NTC thermistor will clear this error.

Common causes of Er:06

  1. 01

    Damaged or pinched NTC wiring harness

    Wiring / connection

    The cable connecting the NTC thermistor to the control board may be pinched by the drum, worn through at a routing point, or have two conductors touching. Inspect the full length of the harness for visible damage, melted insulation, or exposed wires.

  2. 02

    Failed NTC thermistor

    Part replacement

    The NTC thermistor itself can fail internally, creating a short circuit between its terminals. Testing with a multimeter will show near-zero resistance on a shorted unit instead of the expected temperature-dependent resistance.

  3. 03

    Corroded or contaminated connector terminals

    Wiring / connection

    Moisture or detergent residue can cause corrosion or bridging between connector pins at the NTC plug or control board connector, creating a short circuit condition. Inspect connectors for discoloration, buildup, or moisture.

  4. 04

    Chafed wiring from drum movement

    Part replacement

    Repeated drum movement during spin cycles can cause the NTC cable to rub against the tub or chassis, wearing through insulation over time and creating a short. Check areas where the cable passes near moving components.

Frequently asked questions about Er:06

What does Er:06 mean on a Vision washer?
Er:06 means the control board has detected a short circuit in the NTC thermistor circuit. The NTC is the temperature sensor that monitors water temperature during the wash cycle. A short circuit can come from a damaged wiring harness or a failed thermistor component. The washer halts operation when this fault is detected to prevent unsafe conditions.
Can I fix Er:06 myself on a Vision washer?
A knowledgeable DIYer can attempt to diagnose this error by visually inspecting the NTC wiring harness for damage and testing the thermistor with a multimeter. If the wiring has a simple pinch or loose connector, that may be correctable without special tools. Replacing the NTC thermistor is a relatively straightforward repair if the wiring is found to be intact.
Will resetting the washer clear the Er:06 error code?
A power reset may temporarily clear the displayed error, but Er:06 will return as soon as the control board checks the NTC circuit again if the underlying short circuit has not been repaired. The root cause, either the wiring fault or the failed thermistor, must be corrected to permanently resolve the code.
Is it safe to use my Vision washer while it shows Er:06?
No, you should not operate the washer while Er:06 is active. A short-circuited temperature sensor means the control board cannot accurately monitor water temperature, which could lead to improper heating or loss of thermal control. The washer is designed to stop when this fault is detected, and running it in a fault state is not recommended.
How much does it cost to repair Er:06 on a Vision washer?
If only the wiring harness needs to be repaired or rerouted, costs may be limited to labor time alone. If the NTC thermistor requires replacement, parts typically range from a modest to moderate cost depending on availability. Total repair costs including professional labor generally range from around $75 to $200, though this varies by region and service provider.
