IFB Searchable Fault & Error Code Guide
| Code | Condition / Symptom | Engineering Diagnosis & Fix |
|---|---|---|
| dOOR | Door lock switch not engaged / safety latch failure | Inspect door hook alignment, measure door lock PTC solenoid resistance, replace latch. |
| tAP | Water tap closed or inlet valve screen blocked | Verify water pressure >1 bar, clean inlet filter screen, replace solenoid valve. |
| dEF | Drain pump error / water not draining within 6 minutes | Open front drain filter, clear coins/threads from pump impeller, replace drain pump. |
| PF | Power failure / unstable input voltage detected | Test mains wall socket AC voltage 230V ± 10%, verify grounding and neutral. |
| Error 01 | Water level pressure switch (hydrostat) malfunction | Check pressure transducer air tube for lint blockage, replace level sensor. |
| Error 08 | Drum motor drive inverter fault or motor overcurrent | Check motor harness wiring, inspect main PCB motor drive IGBT transistors. |
