Frigidaire Dishwasher Error Code rA

The rA code means the control board has sensed a problem with the reed switch in the rinse aid dispenser. The reed switch is a small magnetic sensor that communicates dispenser status to the control. The code is triggered when the control receives a signal from that switch that is absent or outside of the expected range. Checking the wiring connections at the dispenser is the first step in diagnosing this fault.

The rA code is related to the rinse aid dispenser sensor and does not indicate a water leak, electrical hazard, or heating system problem. Your dishwasher will likely still run, but rinse aid dispensing may not function correctly, which can result in spots or film on dishes and glassware. It is best to address the fault before continued long-term use.

If only the wiring connections need to be cleaned or reseated, the repair may cost nothing beyond your time. If the reed switch or the full rinse aid dispenser assembly needs to be replaced, parts typically range from around $20 to $80 depending on the specific model, with professional labor adding $75 to $150 or more depending on your area and the technician.

In some cases, yes. Start by inspecting the wiring harness connector at the rinse aid dispenser for loose, corroded, or damaged pins and reseat the connector firmly. If the connections look good, testing the reed switch for continuity with a multimeter is the next step. If the switch has failed, replacing it or the dispenser assembly requires basic disassembly skills and the correct replacement part.

A reset may temporarily clear the code from the display, but if the underlying fault with the reed switch or its wiring is still present, the code will return once the control runs its diagnostic checks again. A reset is not a fix and should only be used to confirm whether the fault is intermittent or persistent after a repair has been made.
