Hotpoint E1

Hotpoint error code E1 indicates: Hotpoint ActiveCare & MaxiSpace 3D Zone Wash Dishwasher: Electronic temperature sensing disconnect E1; microcomputer detects sensor resistance above open-circuit limit (> 200 kΩ)..

The primary root cause for Hotpoint code E1 is: On Hotpoint dishwashers: Wire fractured in door hinge flex loom, corroded terminals on sump NTC probe, or broken sensor internal connection..

To resolve error code E1: Test wiring harness continuity from control board to NTC probe terminals. Measure NTC thermistor resistance (nominal ~48 kΩ at 25°C). Repair broken wiring loom. Press and hold Start/Cancel for 4 seconds until the active program cancels and completes drain cycle.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Hotpoint code E1 persists, the physical component causing On Hotpoint dishwashers: Wire fractured in door hinge flex loom, corroded terminals on sump NTC probe, or broken sensor internal connection. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..

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.
