Common Solahart Faults & Solutions
We specialize in diagnosing and repairing the most common issues found in Solahart systems across the Gold Coast.

Lukewarm or No Hot Water
"Water isn't getting hot enough or you have no hot water at all."
Potential Causes
- •Failed solar sensor or thermostat
- •Element or booster not heating
- •Pump failure (split systems)
- •Cloudy weather combined with a bad booster relay
- •Scale build-up on the element
Our Repair Solution
- Test sensors, thermostat, element, booster, and wiring
- Check solar absorption on the roof panels
- Ensure proper heat transfer
- Replace faulty components with genuine parts

Leaking Roof Panels or Tank
"Water dripping from the roof or rust stains appearing around the solar panels."
Potential Causes
- •Corrosion in the tank
- •Cracked or damaged solar collectors
- •Faulty pipework or loose compression fittings
- •Weather damage from storms or hail
Our Repair Solution
- Isolate the leak and pressure-test the lines
- Repair or replace damaged components
- Check for heat-related expansion issues
- Replace perished rubber unions and seals

Booster Not Kicking In
"Electric booster fails to heat water during cloudy periods or high demand."
Potential Causes
- •Faulty booster element
- •Burnt-out thermostats
- •Wiring or relay failure
- •Off-peak tariff timing issues
Our Repair Solution
- Test electrical continuity
- Verify tariff configuration
- Replace the element if required
- Reset the system so it reliably heats

Temperature Pressure Relief (TPR) Valve Constantly Dripping
"Constant flow of water from the drain line even when not heating."
Potential Causes
- •System overheating during summer
- •Scale buildup preventing valve from seating
- •Valve degraded from UV exposure
- •Tank overpressurized from thermal expansion
- •Valve exceeded 5-year service life
Our Repair Solution
- Replace degraded TPR valves with genuine parts
- Test for over-pressurization causes
- Install TRV (over-temperature relief) tanks if needed
- Adjust system to prevent summer overheating

System Not Heating Despite Sunny Weather
"Solar panels failing to heat water even on bright, sunny days."
Potential Causes
- •Shaded roof panels
- •Air lock in the solar circuit
- •Pipe insulation failures
- •Collector sensor failure
Our Repair Solution
- Check solar absorption
- Remove air locks
- Reinsulate lines and test collectors
- Restore proper flow to roof panels

Circulation Pump Failure (Split Systems)
"Solar pump isn't circulating water to the roof collectors on sunny days."
Potential Causes
- •Scale buildup clogging impeller
- •Impeller vanes damaged or corroded
- •Pump seized from lack of use
- •Controller not activating pump
- •Air lock preventing pump from priming
Our Repair Solution
- Remove circulation pump and inspect
- Clean or replace with genuine parts
- Descale pipework if needed
- Test controller operation

Leaking Solar Collectors & Cracked Glass Panels
"Water running down the roof, pooling in gutters, or dripping from panel connections."
Potential Causes
- •Frost damage from rare cold nights
- •Cracked collector glass from hail or stress
- •Failed O-rings at collector connections
- •Cone seal leaks on closed circuit systems
- •Over-pressurization during summer
Our Repair Solution
- Isolate the leak and pressure-test lines
- Repair or replace damaged components
- Check for heat-related expansion issues
- Replace deteriorated O-rings and seals

Sacrificial Anode Depletion & Premature Tank Rust
"Tank rusting from the inside out due to neglected sacrificial anode replacement."
Potential Causes
- •System installed 10+ years ago, anode never replaced
- •Hard water areas accelerating depletion
- •System serviced but anode skipped
- •Softened water causing rapid deterioration
Our Repair Solution
- Drain the tank and remove access panel
- Extract the depleted anode
- Install a new magnesium anode if tank is sound
- Assess whether tank replacement is necessary

Thermostat Failure & Incorrect Temperature Settings
"Electric boosting running constantly but water stays tepid, or hot water runs out quickly."
Potential Causes
- •Factory preset to 50°C—too low for winters
- •Thermostat reading incorrectly
- •ECO (safety cutout) tripped at 83°C
- •Thermostat contacts worn out
- •Thermostat probe fallen off tank surface
Our Repair Solution
- Test thermostat calibration
- Adjust settings to 60°C minimum
- Replace faulty thermostats
- Reset tripped ECO switches and secure probe
