Part 6: The "Hard Reset" – Clearing Fault Memory & Calibration

6. Common Fault Codes and Diagnostics

• E:18 / F18 (Drain fault) — pump clogged, filter obstructed, drainage hose kinked, pump failed, or PCB not detecting pump rotation. Service action: check filter, clear debris, test pump with direct 230V (if safe), inspect wiring.
• E:15 / F15 (Water inlet fault) — inlet valve blocked, water supply off, faulty pressure switch. Service action: check water supply/valves, measure valve coil resistance (~2–3 kΩ typical), inspect pressure tube for blockages.
• E:09 / F09 (Heating fault) — open/shorted heater or NTC sensor issue. Service action: measure heater resistance (typically 20–40 Ω depending on model), test NTC resistance vs temperature.
• E:03 / F03 (Motor tachometer/drive fault) — motor or inverter problem, check motor connections, measure hall sensors, inspect PCB for burnt components.
• E:17 / F17 (Pressure sensor/overfill) — blocked pressure line or defective pressure switch; inspect and replace as needed.
• Door lock errors — check interlock continuity and connector, replace latch assembly if defective.
