Whirlpool E2

Whirlpool error code E2 indicates: Whirlpool 6th Sense PowerClean Pro & MaxiSpace Dishwasher: AquaStop base pan float switch closed E2; emergency drain activated to prevent residential water flooding..

The primary root cause for Whirlpool code E2 is: On Whirlpool 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 Cancel/Drain button for 5 seconds until drain cycle begins, allow 60s for sump evacuation, then power off and on.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Whirlpool code E2 persists, the physical component causing On Whirlpool 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.
