Symptom / Description

FAULT

De Dietrich Prestige / DWF Inverter Washing Machine: Condenser drying NTC thermistor fault d23; temperature sensing on the condensation duct fails verification.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On De Dietrich washer-dryers featuring Prestige DWF brushless inverter drive, optoelectronic water metering, and anti-vibration cabinet damping: Open or shorted condenser NTC thermistor probe (~20 kΩ at 20°C, ~5 kΩ at 60°C), or moisture ingress in harness plug.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Disconnect sensor plug on condensation duct. Measure resistance (~20 kΩ at 20°C). Replace NTC sensor probe if reading is open or zero ohms. Touch the Power button off, touch and hold Option and Start keys together for 6 seconds until 'rSt' illuminates, then cycle mains power.

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: De Dietrich D23

FAQ TREE

What does error code D23 mean on a De Dietrich appliance?

De Dietrich error code D23 indicates: De Dietrich Prestige / DWF Inverter Washing Machine: Condenser drying NTC thermistor fault d23; temperature sensing on the condensation duct fails verification..

What is the root cause of De Dietrich error code D23?

The primary root cause for De Dietrich code D23 is: On De Dietrich washer-dryers featuring Prestige DWF brushless inverter drive, optoelectronic water metering, and anti-vibration cabinet damping: Open or shorted condenser NTC thermistor probe (~20 kΩ at 20°C, ~5 kΩ at 60°C), or moisture ingress in harness plug..

How do I fix or resolve De Dietrich error code D23?

To resolve error code D23: Disconnect sensor plug on condensation duct. Measure resistance (~20 kΩ at 20°C). Replace NTC sensor probe if reading is open or zero ohms. Touch the Power button off, touch and hold Option and Start keys together for 6 seconds until 'rSt' illuminates, then cycle mains power.

Is it safe to clear De Dietrich error code D23 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if De Dietrich code D23 persists, the physical component causing On De Dietrich washer-dryers featuring Prestige DWF brushless inverter drive, optoelectronic water metering, and anti-vibration cabinet damping: Open or shorted condenser NTC thermistor probe (~20 kΩ at 20°C, ~5 kΩ at 60°C), or moisture ingress in harness plug. must be inspected or replaced.

How do I test electrical resistance for De Dietrich code D23 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 De Dietrich code D23?

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.
