Indesit E4

Indesit error code E4 indicates: Indesit Push&Go & Extra Hygiene DFP Series Dishwasher: Drain evacuation timeout E4; sump pressure switch or virtual sensor indicates tub holds water past 240 seconds drain attempt..

The primary root cause for Indesit code E4 is: On Indesit dishwashers: Clogged sink spigot connection, kinked discharge pipe, foreign object jamming synchronous drain impeller, or worn magnetic motor rotor..

To resolve error code E4: Clean sink drain barb. Unclip drain hose and test flow into bucket. Remove debris around drain pump impeller. Measure motor coil resistance (160–185 Ω). 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 E4 persists, the physical component causing On Indesit dishwashers: Clogged sink spigot connection, kinked discharge pipe, foreign object jamming synchronous drain impeller, or worn magnetic motor rotor. 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.
