Indesit F18

Indesit error code F18 indicates: Indesit Innex & Push&Go MyTime Washing Machine: Excessive foam overdosing warning F18; pressure transducer senses suds accumulation preventing drain pump priming..

The primary root cause for Indesit code F18 is: On Indesit washing machines: High-foaming non-HE detergent used, massive overdose of liquid soap, or partially restricted drain hose trap..

To resolve error code F18: Allow suds to settle naturally for 30 minutes. Run cold rinse cycle without detergent. Clean drain filter and adjust future detergent dosing. Press and hold Start/Pause for 5 seconds until LEDs sequence, rotate selector to '0', and disconnect power for 60s.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Indesit code F18 persists, the physical component causing On Indesit washing machines: High-foaming non-HE detergent used, massive overdose of liquid soap, or partially restricted drain hose trap. 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.
