Indesit F8

Indesit error code F8 indicates: Indesit Push&Go & Extra Hygiene DFP Series Dishwasher: Sump water level inconsistency or diverter fault F8; OWI sensor optical reading conflicts with pressure calculation..

The primary root cause for Indesit code F8 is: On Indesit dishwashers: Fat or grease film coating the optical sensor lens, heavy detergent foaming, or motorized diverter valve (MDV) stuck mid-position..

To resolve error code F8: Clean optical OWI sensor face in sump bottom with warm soapy water and soft sponge. Verify diverter motor resistance (6.0–7.5 kΩ). Recalibrate optical sensor. Press and hold Start/Reset for 5 seconds until drain pump runs, wait 60 seconds, then power cycle ON/OFF.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Indesit code F8 persists, the physical component causing On Indesit dishwashers: Fat or grease film coating the optical sensor lens, heavy detergent foaming, or motorized diverter valve (MDV) stuck mid-position. 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.
