Frigidaire Dishwasher dP, FL and rt Test Mode Displays

dP (drain pump active), FL (water valve open) and rt (relay/triac test) are service test-mode displays on Frigidaire-built dishwashers. They show a diagnostic test in progress and do not indicate a fault on their own.

What dP / FL / rt Means

dP (drain pump active), FL (water valve open) and rt (relay/triac test) are service test-mode displays on Frigidaire-built dishwashers. They show a diagnostic test in progress and do not indicate a fault on their own.

Common Causes of dP / FL / rt

  • Service test mode entered by a technician
  • Key combination pressed accidentally

🔧 One Safe Check You Can Try

If you did not enter test mode intentionally, press Cancel or turn off the breaker for a few minutes and restore power to return to normal operation.

⚠ Why You Shouldn't Go Further Than That

  • None — these are test displays, not faults. Call only if the dishwasher cannot leave test mode after a power reset.

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.

Press Cancel. If water keeps entering with the door closed and power off, shut off the water valve under the sink and book service.

Test mode is intended for diagnostics; running components individually without knowing the sequence can leave water in the tub.
