What E6 means on a ADC washer
The E6 error code on an ADC washer indicates that the water temperature inside the drum has exceeded 95 degrees Celsius (203 degrees Fahrenheit) during a wash cycle. This is a thermal protection event triggered by the machine's temperature monitoring system, which continuously tracks wash water temperature through a thermistor or temperature sensor. When the measured temperature crosses the 95C threshold, the control board registers this condition and halts or interrupts normal cycle progression to prevent damage to fabrics, internal components, or the heating system.
The most likely culprits behind an E6 error are a malfunctioning heating element that fails to shut off when the target temperature is reached, a faulty thermistor or temperature sensor providing inaccurate readings to the control board, or a defective control board that is not correctly regulating the heating circuit. A stuck relay on the control board can cause the heater to remain energized past the programmed setpoint, driving temperatures beyond the safe limit.
When E6 appears, the operator is given two immediate options: pressing START to allow the program to continue, or pressing ESC to terminate the cycle. Continuing the program may be appropriate if the error was caused by a transient sensor anomaly, but if the error recurs consistently, further diagnostic work on the heating element, temperature sensor, and control board is necessary before returning the machine to service.

Common causes of E6
- 01
Faulty thermistor or temperature sensor
Part replacementA defective thermistor can send incorrect temperature readings to the control board, causing it to either allow the heater to run too long or falsely register an over-temperature condition. Check the sensor for resistance values outside the expected range for your water temperature.
- 02
Malfunctioning heating element
Part replacementA heating element that does not cycle off correctly can drive water temperature beyond the 95C threshold. Inspect the element for continuity and check whether it is receiving power at times when it should not be.
- 03
Stuck relay on the control board
Part replacementA relay on the main control board that is welded or stuck in the closed position will keep the heating element energized regardless of temperature feedback. This results in uncontrolled temperature rise and a persistent E6 fault.
- 04
Control board software or hardware fault
Part replacementThe control board may fail to properly regulate the heating circuit even when sensor input is accurate. If the heating element and thermistor both test correctly, the control board itself may need replacement.
- 05
Transient electrical or sensor anomaly
Wiring / connectionIn some cases a momentary voltage spike or brief sensor glitch can trigger the E6 code without an underlying component failure. If the error appears only once and does not return after pressing START, the cause may have been a one-time anomaly rather than a failed part.
