Ignis E9

Ignis error code E9 indicates: Ignis ADL & TuttoinUno Platinum Compact Dishwasher: Overfill chamber safety trip E9; water pressure transducer senses water level beyond maximum safety mark during fill..

The primary root cause for Ignis code E9 is: On Ignis dishwashers: Short-circuited triac feeding constant 230V to inlet solenoid valve, or mineral sediment preventing valve armature closure..

To resolve error code E9: Isolate mains power immediately. Check if water continues filling tub unpowered (valve mechanically failed). If stops, replace shorted power board. Press and hold Start button for 5 seconds to force drain cycle, wait 60s, then switch off power switch.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Ignis code E9 persists, the physical component causing On Ignis dishwashers: Short-circuited triac feeding constant 230V to inlet solenoid valve, or mineral sediment preventing valve armature closure. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Mechanical Pressure Switch Contacts / Inductive Frequency Sensor across Across switch spade contacts with harness unplugged; electronic output: 40Hz–50Hz frequency signal. Expected nominal reading is Mechanical: Continuity 0.0Ω–0.2Ω (Empty: 11-12, Full: 11-14). Electronic: 20Ω–45Ω coil resistance.. Tolerance: Mechanical switch contacts must transition cleanly on gentle breath pressure. Coil ~22Ω ±5%..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
