Electrolux Dishwasher Error Code i43

The i43 code means the analog pressure sensor is producing a signal that is too high, either exceeding the allowed range or holding above it for more than 2.5 seconds. The dishwasher interprets this as an unreliable water level reading and aborts the wash program as a precaution. The fault points to the pressure sensor, its connecting wiring, or the air pressure hose and chamber that feed data to the sensor.

The dishwasher stops the cycle automatically when the i43 code triggers, so there is no immediate flooding risk. However, you should not attempt to bypass or repeatedly restart the machine without diagnosing the fault, since the water level sensor is a critical safety input for the control system. Leave the dishwasher off until the sensor or wiring issue is identified and corrected.

Performing a reset may clear the code temporarily, but the error will return if the underlying fault with the pressure sensor or its wiring has not been resolved. The control board triggers i43 whenever the sensor signal exceeds the threshold for more than 2.5 seconds, so any subsequent cycle will likely abort again. A reset is a reasonable first step to confirm whether the fault is intermittent, but it is not a substitute for proper diagnosis and repair.

Some causes of the i43 error are approachable for a confident DIYer, such as inspecting and reseating the sensor wiring connector, checking the pressure hose for kinks, or cleaning out the air chamber. However, testing the sensor's output signal requires a multimeter and some familiarity with reading electrical values. If the sensor or control board needs replacement, a qualified appliance technician is recommended to ensure the repair is done correctly.

If only the wiring or pressure hose needs attention, out-of-pocket costs may be minimal. Replacing the pressure sensor typically runs in the range of $30 to $80 for the part, plus labor if a technician is doing the work. A full service call including diagnosis and a sensor replacement generally falls between $100 and $250, depending on your location and the technician's rates. If the main control board is at fault, costs will be higher, often ranging from $200 to $400 or more.
