Electrolux Dishwasher Error Code i6B

The i6B code means the dishwasher's heating phase timed out because the water did not reach the required target temperature within the allowed time period. The fault involves the heating system, specifically the heating element, the NTC temperature sensor, or the wiring connecting them to the control board. On some displays, the 'B' character may appear as 'H', so i6H is the same code. After triggering, the heater shuts off for 5 minutes and the dishwasher attempts to auto-recover before continuing the cycle without heating.

The dishwasher will continue running in a degraded mode without heating if the fault does not clear, so there is no immediate safety hazard from using it. However, washing without heated water significantly reduces cleaning effectiveness and does not provide proper sanitization. It is best to address the fault before relying on the dishwasher for regular use.

Repair costs depend on which component has failed. Replacing an NTC temperature sensor is generally the least expensive fix, with parts typically ranging from $15 to $50 and labor costs varying by region. A heating element replacement usually costs more, with parts in the $30 to $100 range depending on the model, plus labor. If the control board is at fault, costs can be considerably higher. Getting a diagnostic quote from a technician before authorizing repairs is advisable.

Some causes of i6B, such as loose or corroded wiring connections, can be addressed by a knowledgeable DIYer who is comfortable working inside an appliance after disconnecting power. However, testing and replacing the heating element or NTC sensor requires a multimeter and basic electrical knowledge. If you are not comfortable with these tasks, a qualified appliance technician is recommended to safely diagnose and repair the fault.

The dishwasher includes a built-in auto-recovery function that shuts the heater off for 5 minutes and then attempts to resume normal operation. A manual reset may temporarily clear the code, but if the underlying fault, such as a failed heating element or bad sensor, is still present, the error will return during the next heating phase. A reset alone is not a repair.
