Common Geyser Problems and How to Fix Them
A geyser in a house is like a side character in a movie that no one remembers until it starts doing things out of character (starts malfunctioning). Whether the water remains cold, starts leaking, or makes strange noises, every issue points to signals that it needs attention.
In this article, we will analyse some of the most common geyser problems and their possible fixes to avoid unnecessary replacement costs, and you will get consistent hot water when you need it.
Below are some of the most frequently reported issues in domestic gijar units, with explanations on what causes them and what you can do about it.
Common Problems in Geysers
1. Geyser Not Heating
The most common issue users face is when the water remains cold despite the indicator light working.
- Possible Causes: Burnt-out heating element, faulty water heater coil, or a malfunctioning thermostat. Sediment accumulation can also insulate the element from heating the water properly.
- Fix: Check the thermostat’s temperature setting and reset it if needed. If there’s still no heat, the element may require replacement. This is a task best handled by professional geyser repair services. Regular descaling helps prevent this from recurring.
2. Leaking Geyser
A leaking geyser looks like a minor issue, but it can be something major as well:
- Possible Causes: Corroded storage tank, worn-out gaskets, or loose pipe connections. Constant pressure fluctuations can also cause hairline cracks.
- Fix: Tighten all visible pipe fittings and inspect the inlet and outlet valves. If leakage continues from the tank body, it usually signals corrosion inside the unit. It means the part might need a replacement. Avoid ignoring even small drips - they worsen over time and waste electricity as the heater keeps reheating lost water.
3. Geyser Making Noise
Humming, popping, or crackling sounds during heating can be unsettling.
- Possible Causes: Sediment or limescale buildup at the bottom of the tank or around the heating element. The trapped water bubbles inside the deposits produce noise.
- Fix: Drain and flush the geyser tank to remove sediment. Installing a softener in areas with hard water can reduce scale formation. If the noise persists, a technician needs to replace the element or inspect for mechanical faults.
4. Water Too Hot or Not Hot Enough
Temperature fluctuations can stem from calibration errors in the geyser thermostat or faults in the heating element itself.
- Possible Causes: Incorrect thermostat settings, damaged sensor, or short-circuited wiring.
- Fix: Turn off the power before checking the thermostat setting. The ideal range is between 55°C and 60°C for daily use. Persistent inconsistency means the thermostat needs replacement. Having this component inspected during annual geyser service prevents abrupt breakdowns.
5. Discoloured or Rusty Water
If your tap releases brown or rust-tinted water, it means your geyser tank is corroded.
- Possible Causes: Rusting of the tank’s inner lining or a failing anode rod that no longer protects the metal surface.
- Fix: Flush out the tank and check if the anode rod has degraded. Replacing this rod every two to three years can extend the geyser’s lifespan. Using stainless-steel tanks reduces this risk in the long term.
6. Low Water Pressure from the Geyser
When water flow weakens, it may look like a plumbing problem, but the geyser can also be the issue.
- Possible Causes: Sediment buildup in the outlet pipe, clogged filters, or partially blocked valves.
- Fix: Turn off the power and water supply, then remove and clean the outlet filters. In some cases, a plumber may need to flush the internal pipes. Maintaining the geyser regularly doesn’t lead to sediment buildup and water blockage.
7. Water Leaking from the Pressure Relief Valve
The safety valve is meant to discharge water when internal pressure rises excessively. If it’s constantly dripping, it is not working properly.
- Possible Causes: High water pressure from the main supply or a malfunctioning valve spring.
- Fix: Check the pressure levels in your main line. If the reading exceeds recommended limits, install a pressure-reducing valve. Otherwise, have the relief valve replaced to maintain safe operation.
8. Geyser Trips the Power Supply
Frequent circuit trips when the geyser is switched on point to electrical faults.
- Possible Causes: Damaged heating element insulation, moisture ingress, or short circuits within the thermostat assembly.
- Fix: Never attempt to open electrical parts without proper tools or experience. Turn off the mains and contact a qualified electrician. Regular inspection of wires and plugs keeps your home safe, especially in older homes where sockets are not properly grounded.
9. Water Taking Too Long to Heat
When it feels like the geyser is running slower than usual, it is not efficient.
- Possible Causes: Mineral buildup on heating elements, reduced power supply, or aging of the unit itself.
- Fix: Descale the tank and element periodically. Verify the power supply voltage, as fluctuating current can slow down heating. If the unit is older than seven years, upgrading to a new electric water heater is more energy-efficient.
10. Burning Smell of Smoke from the Unit
This is an emergency sign and should never be ignored.
- Possible Causes: Short-circuited wiring, melted insulation, or internal overheating due to prolonged use without maintenance.
- Fix: Immediately disconnect the power and water supply. Do not attempt to restart the system. Allow a technician to examine the internal wiring and replace damaged parts. Prevent this by keeping the area around the geyser dry and ensuring no loose connections exist near switches or sockets.
How To Maintain Your Geyser?
To keep your geyser working efficiently and avoid most breakdowns, follow this basic upkeep routine:
- Flush the tank every few months to remove sediment buildup.
- Inspect the heating element at least once a year for signs of scaling or corrosion.
- Schedule regular geyser service to have electrical and plumbing connections checked.
- Monitor for leaks around the tank, valves, and pipe joints.
- Check thermostat settings to maintain the ideal temperature range.
- Clean outlet filters to prevent blockages and maintain steady water flow.
- Use quality components such as thermostats, safety valves, and corrosion-resistant tanks for durability.
- Install a water softener or use descaling agents if you live in a hard-water area.
When to Seek Professional Help?
Even though many minor fixes, like thermostat resetting or flushing the tank, can be done at home, not every issue is safe for DIY. Electrical faults, persistent leaks, or system overheating must be inspected by trained service personnel.
If you neglect professional help, it can be dangerous for your home and also lead to high electric bills.
Authorized service ensures genuine parts replacement, proper sealing, and recalibration. For reliable geyser repair, choose a service center that is reliable and knows how to repair geysers well.
Conclusion
A geyser is a long-term investment that deserves regular maintenance and care. Most failures arise from mineral deposits, corrosion, or skipped maintenance cycles, which strain internal components. Taking time to inspect for leaks, noise, and heating delays saves you from larger repair costs later.
