What RE / RF Means
RE and RF are rinse aid reed switch codes on Frigidaire-built dishwashers: RE indicates the switch reads closed and RF indicates it reads open. Both point to the rinse aid level sensing, not to washing itself.
Common Causes of RE / RF
- Reed switch stuck closed or open
- Dispenser float fault
- Wiring issue at the dispenser
🔧 One Safe Check You Can Try
Fill the rinse aid reservoir and close the cap securely. Run one cycle to see if the code clears. If it persists, book service for the dispenser.
⚠ Why You Shouldn't Go Further Than That
- The switch is part of the in-door dispenser assembly, which requires door disassembly and a new gasket seal to replace.
- 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.
