Root Cause

ROOT CAUSE

The flow meter (reed sensor) is not detecting water pulses entering the machine, or NTC heating sensor fault.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Check the water tap is fully open and inlet hose is clear. 2. Inspect the flow meter reed switch connected to the side matrix. 3. Measure NTC sensor resistance if on washer-dryer.

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: Bosch E14

FAQ TREE

What does error code E14 mean on a Bosch appliance?

Bosch error code E14 indicates: Water Fill Error / Reed Switch Fault.

What is the root cause of Bosch error code E14?

The primary root cause for Bosch code E14 is: The flow meter (reed sensor) is not detecting water pulses entering the machine, or NTC heating sensor fault..

How do I fix or resolve Bosch error code E14?

To resolve error code E14: 1. Check the water tap is fully open and inlet hose is clear. 2. Inspect the flow meter reed switch connected to the side matrix. 3. Measure NTC sensor resistance if on washer-dryer.

Is it safe to clear Bosch error code E14 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bosch code E14 persists, the physical component causing The flow meter (reed sensor) is not detecting water pulses entering the machine, or NTC heating sensor fault. must be inspected or replaced.

How do I test electrical resistance for Bosch code E14 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 Bosch code E14?

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.
