Popping or Crackling During Heating

Signs: See our descaling guide — this is the most preventable noise cause.
Rs 300 - 500 (descaling)Rumbling or Bubbling Sound
Sediment settled at the tank bottom can create a rumbling sound as it's disturbed by heating currents.
Signs: Sound most noticeable during active heating cycles.
Rs 300 - 500 (tank flush)Hissing or Whistling
Often points to the PRV valve, either releasing pressure normally or indicating an internal issue — see our PRV valve problems guide.
Rs 300 - 600Buzzing or Humming Without Heating
An electrical component (relay, thermostat contact) drawing power without successfully heating — worth checking alongside a no-heating symptom.
Signs: See our not heating guide if paired with cold water.
Diagnosis neededFrequently Asked Questions
Is popping/crackling sound dangerous?
Not immediately dangerous, but it's a clear sign of scale buildup that will worsen heating efficiency and can shorten element life if left unaddressed.
Can I keep using the geyser with unusual noise?
For mild popping, yes in the short term, but it's worth scheduling a descale soon since the underlying cause tends to compound over time.
How does the technician diagnose noise remotely?
We can't fully diagnose over the phone, but describing when the noise happens (during heating vs standby, popping vs hissing) helps us come prepared with the likely fix.
Is a sudden loud noise an emergency?
A single loud bang followed by a hissing sound could indicate a PRV or pressure issue worth checking promptly — described further in our PRV guides.
