Never work on electrical components with wet hands or while standing in water
Equipment-Specific Troubleshooting
Pool Pump Troubleshooting
Pump Won't Start:
- Check power at breaker panel
- Test GFCI outlet with test/reset
- Inspect for tripped overload switch
- Verify timer settings if applicable
- Check for loose electrical connections
- Test motor capacitor if accessible
Pump Runs But No Flow:
- Check if pump has lost prime
- Clean skimmer and pump baskets
- Verify adequate water level
- Inspect for air leaks at pump lid
- Check valve positions
- Look for blockages in suction lines
Pool Heater Troubleshooting
Safety Warning: Gas heater problems can be dangerous. If you smell gas, turn off gas supply immediately and call professional.
Basic Checks (Safe for Homeowners):
- Verify thermostat setting and operation
- Check for error codes on display
- Ensure adequate water flow through heater
- Inspect for blocked air intake or exhaust
- Verify electrical connections are secure
Professional Required:

DFW-Specific Equipment Challenges
Extreme Heat Impact
DFW's intense summer heat (100°+ for weeks) creates unique stresses on pool equipment not found in milder climates.
Heat-Related Equipment Stress:
- • Motor overheating and premature failure
- • Plastic components becoming brittle
- • Electrical connections expanding/contracting
- • Seals and gaskets drying out rapidly
Heat Protection Strategies:
- • Shade structures over equipment
- • Proper ventilation around equipment
- • More frequent seal/gasket replacement
- • Professional summer equipment checks
Storm and Weather Damage
DFW's severe weather patterns including hail, high winds, and electrical storms frequently damage pool equipment.
Common Storm Damage:
- • Electrical surge damage to motors/controls
- • Hail damage to equipment housing
