Ariston E2

Ariston error code E2 indicates: Ariston Hotpoint-Ariston 3D Zone Wash MaxiSpace Dishwasher: AquaStop base pan float switch closed E2; emergency drain activated to prevent residential water flooding..

The primary root cause for Ariston code E2 is: On Ariston dishwashers: Sump seal failure, loose hose clamp on circulation pump volute, split water matrix air-break, or leaking door lower gasket..

To resolve error code E2: Unplug unit. Sponge dry base tray. Inspect circulation motor and sump gaskets for active drips. Replace defective hydraulic joint or hose. Hold Start/Reset key for 5 seconds until cycle cancel chime sounds and drain pump completes sump evacuation.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Ariston code E2 persists, the physical component causing On Ariston dishwashers: Sump seal failure, loose hose clamp on circulation pump volute, split water matrix air-break, or leaking door lower gasket. 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.
