Symptom / Description

FAULT

Castor CIE Series / Piano Cottura Induzione Cooktop: Induction coil overheating alarm E2; induction zone temperature sensor exceeds allowable safety cutoff limit (> 240°C).

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Castor (Castor CIE Series / Piano Cottura Induzione Cooktop) models: Empty pan boiled dry at maximum boost power, non-induction pan with thin base concentrating extreme heat, or degraded silicone heat-sink paste on coil NTC.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Switch off cooking zone and allow hob to cool down for 20 minutes. Inspect cookware suitability with a magnet. Verify coil NTC resistance (~100 kΩ at 25°C). Hold Start and Reset keys for 5 seconds until the display clears the alarm code and restores standby status.

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Disconnect 230V electrical mains power before removing appliance side or rear panels.
!Ensure tub water or heating chamber has cooled below 30°C before unclipping thermistor probe.
!Use CAT III 600V/1000V insulated test probes when tng at PCB edge connectors.

3. Preliminary Mechanical & Visual Checks

Inspect sensor immersion sleeve for calcification, limescale scale, or thermal paste degradation.
Check wiring harness for pinch points, chafing against chassis metal, and terminal pin oxidation.
Verify probe is firmly seated in its rubber grommet or bracket inside the water/air circuit.

Frequently Asked Questions: Castor E2

FAQ TREE

What does error code E2 mean on a Castor appliance?

Castor error code E2 indicates: Castor CIE Series / Piano Cottura Induzione Cooktop: Induction coil overheating alarm E2; induction zone temperature sensor exceeds allowable safety cutoff limit (> 240°C)..

What is the root cause of Castor error code E2?

The primary root cause for Castor code E2 is: On Castor (Castor CIE Series / Piano Cottura Induzione Cooktop) models: Empty pan boiled dry at maximum boost power, non-induction pan with thin base concentrating extreme heat, or degraded silicone heat-sink paste on coil NTC..

How do I fix or resolve Castor error code E2?

To resolve error code E2: Switch off cooking zone and allow hob to cool down for 20 minutes. Inspect cookware suitability with a magnet. Verify coil NTC resistance (~100 kΩ at 25°C). Hold Start and Reset keys for 5 seconds until the display clears the alarm code and restores standby status.

Is it safe to clear Castor error code E2 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Castor code E2 persists, the physical component causing On Castor (Castor CIE Series / Piano Cottura Induzione Cooktop) models: Empty pan boiled dry at maximum boost power, non-induction pan with thin base concentrating extreme heat, or degraded silicone heat-sink paste on coil NTC. must be inspected or replaced.

How do I test electrical resistance for Castor code E2 using a multimeter?

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..

What safety protocol must be followed before servicing Castor code E2?

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.
