DISPATCHAlways disconnect appliance from 230V/400V mains before opening panels. Use CAT III multimeter for circuit testing.
Frequently Asked Questions: Samet H21
FAQ TREEWhat does error code H21 mean on a Samet appliance?
Samet error code H21 indicates: Samet Enamelled Vitroceramic & Induction Cooktop with Safety Gas Burners: Operational diagnostic fault code H21 signaled by internal electronics. Pan detection failure or insufficient magnetic permeability of cookware base (<0.7 relative).
What is the root cause of Samet error code H21?
The primary root cause for Samet code H21 is: On Samet kitchen suites engineered with resonant induction generator inverter stage, 100 kΩ coil thermistor, 10 kΩ heatsink NTC, 12V DC fan with tachometer, and fast gas safety thermocouples: Non-ferromagnetic aluminum or copper cookware base, concave distorted pan base, or resonant circuit frequency error Multimeter diagnostic parameter: pan base must attract permanent magnet with strong pull; minimum base contact diameter must be >=120 mm..
How do I fix or resolve Samet error code H21?
To resolve error code H21: Safely de-energize the appliance at the electrical distribution board. Unplug wiring connector from the affected component and verify with a digital multimeter: test cookware with permanent neodymium magnet; verify flat base contact with straightedge across pan bottom. Inspect spade lugs for signs of heat discoloration. Replace defective component, restore electrical supply, and perform system reset: Switch off electrical isolator switch for 60 seconds. Restore power, touch Key Lock key for 7 seconds continuously until lock icon turns off.
Is it safe to clear Samet error code H21 by resetting power?
Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Samet code H21 persists, the physical component causing On Samet kitchen suites engineered with resonant induction generator inverter stage, 100 kΩ coil thermistor, 10 kΩ heatsink NTC, 12V DC fan with tachometer, and fast gas safety thermocouples: Non-ferromagnetic aluminum or copper cookware base, concave distorted pan base, or resonant circuit frequency error Multimeter diagnostic parameter: pan base must attract permanent magnet with strong pull; minimum base contact diameter must be >=120 mm. must be inspected or replaced.
How do I test electrical resistance for Samet code H21 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 Samet code H21?
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.
