Oven

Symptom / Description

FAULT

Core temperature probe (meat thermometer) circuit fault detected on the oven.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

Corroded or loose plug connector, wire break in the harness, defective core temperature probe, or faulty evaluation module on the oven control unit.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Disconnect mains power, inspect the plug socket and wiring harness between the probe jack and the evaluation module, and measure the core temperature sensor resistance with a multimeter. Replace the probe, harness, or evaluation module if out of specification.

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 E516

FAQ TREE
What does error code E516 mean on a Bosch appliance?

Bosch error code E516 indicates: Core temperature probe (meat thermometer) circuit fault detected on the oven..

What is the root cause of Bosch error code E516?

The primary root cause for Bosch code E516 is: Corroded or loose plug connector, wire break in the harness, defective core temperature probe, or faulty evaluation module on the oven control unit..

How do I fix or resolve Bosch error code E516?

To resolve error code E516: Disconnect mains power, inspect the plug socket and wiring harness between the probe jack and the evaluation module, and measure the core temperature sensor resistance with a multimeter. Replace the probe, harness, or evaluation module if out of specification.

Is it safe to clear Bosch error code E516 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bosch code E516 persists, the physical component causing Corroded or loose plug connector, wire break in the harness, defective core temperature probe, or faulty evaluation module on the oven control unit. must be inspected or replaced.

How do I test electrical resistance for Bosch code E516 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 E516?

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.
