Quick Answer
Pool timer issues are common after power outages or with aging equipment. First, verify the timer has power and shows the correct time. Check timer pins or digital settings, ensure they're properly positioned for your desired schedule. Test manual override to confirm equipment works. For mechanical timers, bent or missing pins are the most common issue. Digital timers may need reprogramming after power loss. Most timer problems are simple DIY fixes.

Timer Troubleshooting Steps
Step-by-Step Diagnosis
Check Power Supply
Verify timer has power. Look for display or clock movement.
Test Manual Override
Try manual on/off switches to verify equipment works independently.
Inspect Timer Pins/Trippers
Check for bent, missing, or loose timer pins on mechanical timers.
⚠️ Warning: Turn off power before adjusting timer mechanisms
Verify Current Time
Ensure timer shows correct time. Power outages often reset timers.
Check All Connections
Look for loose wires at timer terminals and equipment connections.
⚠️ Warning: Always turn off power before checking electrical connections
Test Timer Motor
Listen for timer motor running (mechanical) or check digital display.
Fixing Common Timer Issues
Mechanical Timer Problems
Timer Not Keeping Time
Clock gains or loses time daily
Solution: Timer motor likely worn out. Replace timer motor or entire timer.
Equipment Won't Turn On/Off
Timer dial turns but nothing happens
Solution: Check pins/trippers are firmly in place. Test manual lever. Check wire connections.
Timer Making Noise
Grinding or clicking sounds
Solution: Lubricate gears with timer lubricant. If noise persists, replace timer.
Digital Timer Problems
Display Blank or Dim
Can't see timer display
Solution: Check power supply. Replace battery if equipped. May need new timer.
Lost Programming
Settings erased after power outage
Solution: Replace backup battery. Reprogram all schedules. Document settings.
Buttons Not Working
Can't change settings
Solution: Clean button contacts. Check for moisture damage. May need replacement.
Timer Wiring Problems
No Power to Timer
Timer completely dead
Solution: Check breaker. Test voltage at timer. Look for burned wires.
Timer Has Power But Equipment Won't Run
Manual override works but timer doesn't
Solution: Check load side connections. Test timer contacts with meter.
Intermittent Operation
Sometimes works, sometimes doesn't
Solution: Tighten all connections. Look for corrosion. Check for loose pins.
Timer Programming Tips
Optimal Pool Equipment Schedules
🏊 Pump/Filter Schedule
Summer: 8-12 hours daily (peak: 6am-10am, 4pm-8pm)
Winter: 4-6 hours daily (mid-day when warmer)
Tip: Run during off-peak electric rates for savings
🧂 Salt System Schedule
Run Time: Same as pump (cannot run without flow)
Production: Adjust percentage based on demand
Note: Reduce runtime in winter, increase in summer
🤖 Cleaner Schedule
Frequency: 2-3 hours, 3-4 times per week
Best Time: Early morning before swimming
Tip: Stagger with pump schedule for efficiency
💡 Pool Light Schedule
Evening: Sunset to 10-11 PM
Safety: Motion sensor for late night
Energy: LED lights use 80% less power
Programming Best Practices:
- • Always overlap pump and accessory schedules
- • Avoid running high-draw equipment simultaneously
- • Consider your utility's time-of-use rates
- • Adjust seasonally for temperature and usage
- • Keep written backup of all settings
