Electrolux Dishwasher Error Code iB1

The iB1 code means the dishwasher has lost communication with the turbidity sensor, which is the component that measures how dirty the wash water is. When this connection is interrupted, the control board cannot receive soil level data from the sensor. The dishwasher will continue to operate but will default to treating every cycle as a heavily soiled load. Note that some display panels may show this code as iH1 due to how the letter B is rendered on the screen.

Yes, the dishwasher is designed to continue running cycles when this code is active. It compensates for the lost sensor data by defaulting to a high soil level setting. However, running in this mode may use more water and energy than normal since the machine cannot optimize the cycle based on actual load conditions. It is best to address the fault when convenient rather than leaving it unresolved long-term.

If the fault is only a loose connector or minor corrosion, the repair may cost very little beyond your time. Replacing a wiring harness section typically runs between $20 and $60 for parts. A new turbidity sensor generally falls in the $30 to $80 range for the part alone. If a professional technician is needed, expect to add $100 to $200 or more in labor costs depending on your area.

Yes, in many cases this fault can be resolved without professional help. Start by inspecting the turbidity sensor wiring and connector in the sump area for loose, corroded, or damaged connections. Reseating a loose connector or cleaning corroded pins is a straightforward repair. If the wiring and connector are in good condition, the sensor itself may need to be replaced, which requires some disassembly of the sump area.

A power reset may temporarily clear the code from the display, but the fault will return if the underlying wiring or sensor problem is not fixed. The iB1 code is triggered by an active communication failure, so the error will reappear as soon as the control board attempts to read the turbidity sensor during the next cycle. A permanent fix requires resolving the wiring, connector, or sensor issue.
