What FC Means
FC is the drying fan error on the DW80T5040US-series service manual: the control checks the drying fan motor speed and expects it to reach around 3,000 RPM; after repeated retries fail to reach that, the control stores FC. This applies to fan-assisted-drying dishwasher models with a drying fan, not older models without one.
Common Causes of FC
- Drying fan motor not turning at the speed the control expects
- Drying fan wiring or the fan motor has failed
🔧 One Safe Check You Can Try
Switch the dishwasher off at the breaker for about a minute, then restart and run a Normal cycle. If FC keeps returning, the drying fan itself — not a setting or a clog — is the likely cause.
⚠ Why You Shouldn't Go Further Than That
- The drying fan sits inside the tub housing behind panels a technician opens to test and replace it.
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.
