With over 20 years of experience repairing geysers, we’ve encountered every common issue. Here are some of the most frequent geyser problems we fix, along with their usual causes and how we resolve them:
No Hot Water
Cause: Faulty heating element or thermostat.
Solution: Replace the heating element or thermostat to restore hot water.
Water Temperature Too Hot or Too Cold
Cause: Malfunctioning thermostat or incorrect settings.
Solution: Adjust or replace the thermostat for proper temperature control.
Water Leaking from Geyser
Cause: Corroded tank, loose fittings, or faulty pressure relief valve.
Solution: Tighten fittings, replace valves, or replace the geyser tank if necessary.
Geyser Making Loud Noises
Cause: Sediment buildup causing popping or rumbling sounds.
Solution: Flush the tank to remove sediment or replace damaged heating elements.
Geyser Switch Trips Frequently
Cause: Electrical faults, damaged thermostat, or grounding issues.
Solution: Inspect wiring, replace faulty components, and ensure proper grounding.
Water Pressure Drops When Using Hot Water
Cause: Blocked pipes or faulty pressure relief valve.
Solution: Clear blockages or replace the valve.
Rusty or Discolored Water
Cause: Corrosion inside the tank or old pipes.
Solution: Replace the anode rod, flush the tank, or replace the geyser if severely corroded.
Water Takes Too Long to Heat
Cause: Faulty heating element or thermostat.
Solution: Repair or replace faulty parts to restore heating efficiency.
Geyser Overflows or Drips Water
Cause: Faulty pressure relief valve or excessive pressure buildup.
Solution: Replace the valve and check pressure levels.
Geyser Not Switching On
Cause: Faulty electrical connections or damaged thermostat.
Solution: Inspect and repair wiring or replace the thermostat.
Pilot Light Keeps Going Out (Gas Geysers)
Cause: Faulty thermocouple or gas supply issues.
Solution: Replace thermocouple or fix gas supply.
Geyser Smells Strange or Burning Odor
Cause: Electrical faults or sediment overheating.
Solution: Inspect wiring, replace heating element, and flush tank.
Water Heater Tank Rusting
Cause: Old age and corrosion.
Solution: Replace the geyser tank to avoid leaks.
Faulty Thermostat
Cause: Wear and tear or electrical failure.
Solution: Replace the thermostat.
Heating Element Short Circuits
Cause: Damage from sediment buildup or electrical fault.
Solution: Replace the heating element and clean the tank.
Temperature Fluctuates During Use
Cause: Defective thermostat or mixing valve issues.
Solution: Repair or replace the faulty parts.
Water Dripping from Temperature and Pressure Relief Valve
Cause: Valve malfunction or excess pressure.
Solution: Replace the valve and check system pressure.
Leaking Pipe Connections
Cause: Loose or corroded fittings.
Solution: Tighten or replace pipe fittings.
Low Hot Water Flow
Cause: Blocked pipes or sediment buildup.
Solution: Clear pipes and flush the tank.
Geyser Tank Crack
Cause: Rust and wear over time.
Solution: Replace the entire geyser tank.
Water Heater Not Filling Properly
Cause: Faulty inlet valve or blockage.
Solution: Repair or replace the inlet valve.
Electricity Bills Rising Suddenly
Cause: Inefficient geyser operation due to faulty parts or poor insulation.
Solution: Service the geyser and replace worn parts to improve efficiency.
Water Heater Trip Switch Keeps Clicking
Cause: Electrical overload or faulty wiring.
Solution: Inspect and repair wiring and components.
Leaks from Drain Valve
Cause: Loose valve or damaged seal.
Solution: Tighten or replace the drain valve.
Pilot Light Won’t Ignite (Gas Geysers)
Cause: Blocked gas line or faulty ignition system.
Solution: Clear blockage or repair ignition.
Geyser Tank Overheating
Cause: Thermostat failure or sediment buildup.
Solution: Replace thermostat and flush tank.
Cold Spots in Hot Water Supply
Cause: Partial heating element failure.
Solution: Replace the faulty heating element.
Water Heater Makes Hissing Sounds
Cause: Water leaking onto hot surfaces or pressure issues.
Solution: Inspect for leaks and check pressure relief valve.
Water Contamination
Cause: Corroded tank or damaged anode rod.
Solution: Replace anode rod or geyser tank.
Geyser Takes Too Much Time to Reheat After Use
Cause: Sediment buildup or thermostat issues.
Solution: Flush the tank and replace the thermostat if needed.
