What rA Means
rA on Frigidaire-built dishwashers is a rinse aid dispenser reed switch failure — the control cannot read the rinse aid level correctly. Washing is not the issue; the level sensing is.
Common Causes of rA
- Faulty reed switch in the dispenser
- Dispenser assembly failure
- Wiring fault to the dispenser
🔧 One Safe Check You Can Try
Make sure the rinse aid reservoir is filled and the cap is fully closed, then run a cycle. If rA persists, the dispenser or its switch needs replacement, which is a service call.
⚠ Why You Shouldn't Go Further Than That
- The dispenser is mounted in the inner door and removing it requires separating the door panels and resealing the dispenser gasket.
- Damage caused during a repair attempt may not be covered by your warranty — check your warranty terms first.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
