Symptom / Description

FAULT

Water is not heating up, resulting in poor wash performance and wet dishes.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

The heating element has failed, the NTC temperature sensor is faulty, or there's a problem with the wiring or control board relay for the heater.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Test the heating element for continuity. Check the NTC sensor's resistance. Inspect wiring. If components are good, the control board may be the issue.

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: Bompani E3

FAQ TREE

What does error code E3 mean on a Bompani appliance?

Bompani error code E3 indicates: Water is not heating up, resulting in poor wash performance and wet dishes..

What is the root cause of Bompani error code E3?

The primary root cause for Bompani code E3 is: The heating element has failed, the NTC temperature sensor is faulty, or there's a problem with the wiring or control board relay for the heater..

How do I fix or resolve Bompani error code E3?

To resolve error code E3: Test the heating element for continuity. Check the NTC sensor's resistance. Inspect wiring. If components are good, the control board may be the issue.

Is it safe to clear Bompani error code E3 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bompani code E3 persists, the physical component causing The heating element has failed, the NTC temperature sensor is faulty, or there's a problem with the wiring or control board relay for the heater. must be inspected or replaced.

How do I test electrical resistance for Bompani code E3 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 Bompani code E3?

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.
