Water Heater Problems We Repair & Service
Water Heater Not Heating At All
A geyser that turns on — power light glowing — but delivers no hot water at all is one of the most common complaints, especially with storage water heaters after a year or two of hard-water use.
Common Causes
- Heating element (rod) burnt out
- Thermostat failed in the off position
- Thermal cut-out (safety fuse) tripped and not reset
- Loose or damaged internal wiring connection
- No power reaching the unit despite the indicator light
Our technician checks the element, thermostat, and wiring at your home before recommending a part replacement.
Water Running Too Hot / Thermostat Not Cutting Off
Water that comes out scalding hot regardless of the temperature setting is a safety concern, not just a comfort issue — it usually means the thermostat isn't cutting power to the element when it should.
Common Causes
- Thermostat stuck closed / not cutting off
- Wrong or faulty replacement thermostat fitted previously
- Sediment coating the thermostat sensor, causing a delayed reading
- Safety thermal cut-out itself faulty
⚠️ If water is dangerously hot, switch off the geyser at the power point and avoid direct use until it's checked.
Water Heater Leaking
Water dripping from the bottom of a storage geyser, from the pipe connections, or from the pressure relief valve all point to different faults — the location of the leak matters for diagnosis.
Common Causes
- Corroded or cracked inner tank (common in older storage geysers)
- Faulty or worn pressure relief valve
- Loose inlet/outlet pipe connections
- Damaged tank gasket or seal
- Excess pressure build-up due to a blocked outlet
A leaking pressure relief valve is often a simple, low-cost fix — a leaking tank usually means the unit needs replacing rather than repairing.
Water Heater Tripping MCB / Electrical Fault
A geyser that trips the MCB or ELCB the moment it's switched on has a genuine electrical fault — this should not be ignored or repeatedly reset, since it usually means current is leaking somewhere it shouldn't.
Common Causes
- Heating element damaged and leaking current to the tank body
- Moisture inside the terminal/wiring box
- Faulty ELCB/MCB unrelated to the geyser itself
- Damaged internal wiring or insulation
⚠️ Don't keep resetting the breaker and using the geyser — a current leakage fault is an electric shock risk until it's fixed.
Rumbling Noise / Slow Heating (Sediment Build-Up)
A popping, rumbling, or knocking sound during heating, along with water taking longer than usual to heat, is a classic sign of sediment and mineral scale build-up inside the tank — very common in hard-water areas.
Common Causes
- Mineral/scale build-up coating the heating element
- Sediment layer at the bottom of the tank
- Reduced heating efficiency from scale insulation on the element
- No periodic tank flushing done since installation
A descaling service restores heating speed and reduces strain on the element, extending its life.
Water Heater Not Turning On / No Power
No indicator light, no sound, nothing at all when switched on usually means the fault is in the power supply or an internal safety cut-out rather than the heating element.
Common Causes
- Tripped MCB or faulty wall switch
- Blown thermal fuse / safety cut-out not reset
- Damaged power cord or internal wiring
- Faulty indicator light only (unit may still be heating)
Check the switch and MCB first. If those are fine, the fault is internal and needs a technician visit.
