Scholtès A13

Q: What does error code A13 mean on a Scholtès appliance?

Scholtès error code A13 indicates: Scholtès LTE / LPE Maxi Plate 14-Place Integrated Dishwasher: Diagnostic fault code A13 registered by the microcomputer controller. Turbidity sensor optical measurement out of calibration range.

Q: How do I fix or resolve Scholtès error code A13?

To resolve error code A13: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: clean turbidity sensor optic lens in sump and check 5V DC supply. Inspect contacts for pin oxidation or loose terminals. Replace defective part if out of tolerance, re-energize and clear error: Press and hold the P (Program) and Start buttons simultaneously for 4 seconds until all LEDs illuminate and the machine emits a beep, then turn selector to 0 to cancel the error.

Q: Is it safe to clear Scholtès error code A13 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Scholtès code A13 persists, the physical component causing On Scholtès appliances engineered with EVO-3 / Arcadia hydraulic control platform with variable-frequency wash pump, active siphonage detection, and calibrated NTC immersion thermistor: infrared lens coated with detergent film Metrological tolerance verification: clean rinse voltage > 4.2V DC; dirty < 1.5V DC.. must be inspected or replaced.

Q: How do I test electrical resistance for Scholtès code A13 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..

Q: What safety protocol must be followed before servicing Scholtès code A13?

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.

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.
