Electrolux Dishwasher Error Code rA

The rA code means the control board has detected a problem with the reed switch in the rinse aid dispenser. The reed switch monitors rinse aid level by responding to a magnet or float inside the dispenser, and the control has received an unexpected or invalid signal from it. The dishwasher will alert you to this fault so the dispenser circuit can be inspected and repaired before rinse aid dispensing is affected.

The rA code indicates a sensor fault rather than a water leak or electrical hazard, so the risk of immediate damage is low. However, the dishwasher may not dispense rinse aid correctly while the fault is active, which can result in spotty or streaky dishes. It is best to address the fault before continuing regular use.

Repair costs depend on whether the issue is a simple wiring fix or a full component replacement. If only a connector needs to be reseated or a wire repaired, costs can be minimal. Replacing the rinse aid dispenser assembly typically costs between 30 and 80 dollars for the part, with professional labor adding another 80 to 150 dollars depending on your location and service provider.

Start by inspecting the reed switch and its wiring inside the rinse aid dispenser compartment. Check the wiring connectors for corrosion or loose connections and reseat them if needed. Test the reed switch with a multimeter for proper continuity. If the switch is faulty or the wiring is damaged beyond repair, replacing the affected component will clear the fault.

A reset may temporarily clear the rA code from the display, but the code will return if the underlying fault with the reed switch or its wiring has not been corrected. Resetting without repairing the cause is not a permanent solution. The control will re-detect the problem once it cycles through and checks the dispenser circuit again.
