POOL HEATER REPAIR SPECIALISTS IN SW FLORIDA

Southwest Florida winters require reliable pool heating.

GAS VS. ELECTRIC HEAT PUMP

Gas heaters heat your pool water faster and perform well regardless of air temperature. Electric heat pumps are more energy-efficient for regular use but require warm ambient air to operate effectively. If your current system is repeatedly failing, we can advise on the best long-term solution for your usage pattern and budget — in writing, with no obligation.

Common Error Codes

HEATER ERROR CODES — WHAT THEY MEAN

Don't guess. These codes indicate specific failures that require professional diagnosis. Call us if you see any of these displayed on your heater.

LOW FLOW / CHECK FLOW
Insufficient Water Flow
Water is not moving through the heater fast enough. Usually caused by a dirty filter, failing pump, or broken pressure switch inside the heater unit.
IGN FAIL / IGNITION
Ignition System Failure
The gas burner is not igniting. Causes include a faulty igniter, gas supply issue, or failed gas valve. Do not attempt to manually ignite — call for service.
HI LIMIT / OVER TEMP
High Temperature Limit
The heater has overheated and shut down for safety. Can indicate a flow restriction, thermostat failure, or damaged heat exchanger.
SENSOR FAULT
Temperature Sensor Error
One or more temperature sensors has failed or disconnected. The heater cannot accurately monitor water temperature and will not operate safely.
SERVICE HEATER
General System Fault
A general fault code indicating the control board has detected an abnormal condition. Professional diagnostic is required to identify the specific failure.
E05 / E06 / AO
AquaCal Heat Pump Codes
AquaCal error codes typically indicate refrigerant pressure issues, sensor failures, or compressor faults. Requires specialized heat pump diagnostic equipment.

Common Questions

POOL HEATER REPAIR — FAQ

A Check Flow or Low Flow error means water is not moving through the heater at the required rate. The most common causes are a dirty or clogged filter restricting flow, a pump that is losing suction, or a failed water pressure switch inside the heater. Our technician will diagnose the exact cause and replace the faulty component on-site.
Pool heater repair in Naples ranges from $150 for minor component replacements to $900 or more for control board or heat exchanger work. Wild Blue charges a $150 diagnostic fee credited to your repair. You receive a written estimate before any work begins — no surprises.
Yes. Wild Blue Pool Repair services AquaCal heat pumps across Bonita Springs, Naples, and Estero. AquaCal units are very common in Southwest Florida's luxury communities and our technician is experienced in diagnosing their specific fault codes and refrigerant-side issues.
Ignition failure in a Pentair MasterTemp is typically caused by a faulty electronic igniter, a failed gas valve not opening properly, or a failed pressure switch preventing the system from confirming proper water flow. Our technician will test each component systematically to isolate the fault.
If your heater is under 10 years old and the repair is under 40–50% of replacement cost, repair usually makes sense. Heaters over 12–15 years with recurring failures may be better replaced. We will give you an honest, written recommendation after the diagnostic — our goal is to give you the right solution, not the most expensive one.
