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: Atlantic ER 24

FAQ TREE
What does error code ER 24 mean on a Atlantic appliance?

Atlantic error code ER 24 indicates: Inaccurate temperature control.

What is the root cause of Atlantic error code ER 24?

The primary root cause for Atlantic code ER 24 is: Fault detected with the upper temperature sensor (NTC)..

How do I fix or resolve Atlantic error code ER 24?

To resolve error code ER 24: The temperature sensor needs to be tested and replaced if it is out of specification.

Is it safe to clear Atlantic error code ER 24 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Atlantic code ER 24 persists, the physical component causing Fault detected with the upper temperature sensor (NTC). must be inspected or replaced.

How do I test electrical resistance for Atlantic code ER 24 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 Atlantic code ER 24?

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.
