How to troubleshoot Geyser Service issues at home

Quick answer (read this first)

• No hot water? Verify power/gas supply and thermostat settings first.
• Geyser leaking? Inspect all pipes, connections, and the tank for visible drips.
• Low water pressure? Clean clogged aerators and ensure the geyser’s inlet valve is fully open.

Safety first

• Always turn off the main electricity breaker or gas supply to the geyser before any inspection or work.
• Do not attempt complex electrical wiring or gas line repairs yourself; these require professional expertise.
• Ensure proper ventilation, especially when working with gas geysers, to avoid gas buildup.
• Wear protective gloves and eye protection when dealing with hot water or tools.
• Be cautious of extremely hot water when draining or inspecting components.

Tools you may need

• Screwdriver set (flathead and Phillips)
• Adjustable wrench
• Pliers
• Flashlight
• Bucket and towels (for potential water spills)

Step-by-step

Step 1

Step 1: Prioritize Safety. Completely turn off the electricity supply at the main breaker or close the gas valve to the geyser before proceeding.

Step 2

Step 2: Verify Power or Gas Supply. For electric geysers, confirm the power switch is on and the circuit breaker is not tripped. For gas geysers, ensure the main gas valve is fully open and the pilot light is lit (if applicable).

Step 3

Step 3: Inspect for Leaks. Visually check all pipes, connections, and the geyser tank itself for any signs of water leakage or drips. Gently tighten any visibly loose fittings.

Step 4

Step 4: Examine Thermostat or Regulator. If there’s no hot water, gently check and adjust the thermostat on electric geysers or the gas regulator on gas geysers. Do not force adjustments; refer to your manual.

Step 5

Step 5: Address Low Water Pressure. If water flow is weak, unscrew and clean showerheads or faucet aerators for mineral buildup. Also, confirm the geyser’s main water inlet valve is completely open.

Step 6

Step 6: Flush Sediment (Electric Geysers Only). If you hear rumbling noises or notice reduced efficiency, carefully drain a small amount of water from the geyser’s drain valve. Caution: Drained water will be very hot; wear protective gloves and ensure a safe disposal method.

Step 7

Step 7: Check Overload Protector (Electric Geysers). Locate and press the red reset button, often found near the thermostat, if your electric geyser isn’t heating. Consult your geyser’s manual for its exact location if needed.

Common mistakes

• Forgetting to turn off electricity or gas supply before starting any work, risking serious injury.
• Attempting to repair complex electrical wiring or gas line issues without proper training or certification.
• Over-tightening connections, which can strip threads, damage pipes, or cause new leaks.
• Ignoring minor leaks, as they can quickly escalate into larger, more costly problems.
• Adjusting the thermostat too high, which can be inefficient, increase energy bills, and pose a scalding risk.

When to call a professional

• If there are persistent leaks from the geyser tank itself (not just external pipes or connections).
• Any signs of electrical sparking, burning smells, repeated circuit breaker trips, or visible damage to wiring.
• Strong gas odors, gas leaks, or persistent pilot light issues you cannot safely resolve after basic checks.
• A complete lack of hot water even after performing all basic troubleshooting steps listed above.
• Unusual loud banging, rumbling, or whistling noises coming from inside the geyser tank that persist after flushing sediment.
