Fusion 44 X Troubleshooting Guide

​🔌ISSUE #1: System Won’t Power On

​Possible Causes:
 

  • Power supply interruption or tripped breaker

  • Loose power cord or connection

  • Internal fuse or circuit issue

  • Timer not sending power to unit

Step-by-Step Troubleshooting:
 

  1. Verify the outlet or breaker is supplying power.

  2. Ensure all cables are securely connected and not damaged.

  3. Check timer settings to ensure power is being sent to the unit.

  4. If no signs of power (no lights/display), contact technical support.

Resolution:
 

Once power is restored, the display should light up and begin cycling. If it doesn’t, internal servicing may be required. +most issues can be resolved with making sure you replace the acid at 150 working hrs.
 

  • 4hrs of daily runtime of unit = 5weeks of acid usage (then replace).

  • 6hrs = 4weeks of acid usage

  • 8hrs = 3weeks of acid usage 

  • 10hrs = 2weeks of acid usage (we recommend using 1gal of Acid Magic) or Testing for and using a phosphate remover. 

💧 ISSUE #2: Water Appears Cloudy or Dirty

​Possible Causes:
 

  • Inadequate system runtime or pump circulation

  • Low hydrogen ion output

  • Incorrect water chemistry (pH, alkalinity, phosphate levels)

  • High organic load (sunscreen, sweat, debris)

  • Clogged filters or poor filtration

  • Fusion 44X not operating at full capacity (display under “11”)

  • Timer settings are too short or are not activating system properly

Resolution:
 

Water should clear in 12–48 hours once chemistry, flow, and runtime are corrected. If not, check other related issues.

Step-by-Step Troubleshooting:
 

  1. Check Fusion 44 X display; if reading is low or “0”, refer to other issues.

  2. Ensure pump is running 2850–3000 RPM* with suction at black hose.

  3. Run system 6–12 hrs/day depending on pool size and usage.

  4. Backwash or clean filters and clear pump baskets.

  5. Balance water: pH 7.2–7.6, TA 80–120 ppm, Phosphates ≤ 100 ppb.

  6. Run system 24–48 hours continuously to hydrogen shock.

  7. Brush and inspect dead zones in pool for trapped debris or algae.

⚡ ISSUE #3: Low Hydrogen Ion Output

​Possible Causes:
 

  • Water flow is restricted or too low

  • System not running long enough

  • Timer improperly set

  • Digital monitor shows low or zero value

  • Incorrect water chemistry (e.g., pH imbalance)

Resolution:
 

If display shows 11–22 and water clears in 24–48 hrs, system is operating correctly. If not, refer to related issues. 

Step-by-Step Troubleshooting:
 

  1. Check digital monitor for output between 11–22.

  2. Verify pump is at 2850–3000 RPM with suction at black acid hose.

  3. Ensure system runs 6–12 hours/day depending on pool size.

  4. Test and adjust pH (7.2–7.6) 

  5. Power cycle system and observe display.

  6. Consider increased pool load; extend runtime if needed.

🚫 ISSUE #4: Flow Issues / No Suction at Black Feed Hose Detected

​Possible Causes:
 

  • Pump not running at correct RPM

  • Suction side blockage

  • Air in the line or system not primed

  • Hose kinked or disconnected

  • Dirty filter causing back pressure

  • Internal obstruction in Fusion 44X intake

Resolution:
 

Once suction is restored, hydrogen ion delivery resumes. If still no suction, see related power or output issues.

Step-by-Step Troubleshooting:
 

  1. Check for suction at black hose while system is on.

  2. Ensure pump is running at 2850–3000 RPM*.

  3. Check hose for kinks or obstructions.

  4. Empty pump and skimmer baskets.

  5. Backwash or clean filter.

  6. Prime pump and remove air in system.

  7. Inspect Fusion 44 X chamber intake for blockage.

🧪 ISSUE #5: pH or Other Chemical Parameters Out of Range

​Possible Causes:
 

  • pH not in optimal range

  • Total alkalinity is too high or low

  • High phosphate or cyanuric acid levels

  • Recent chemical additions

  • Poor test kit accuracy or expired reagents

Resolution:
 

Proper water balance allows the Fusion 44 X to perform optimally. If issues persist, revisit runtime and output readings. 

Step-by-Step Troubleshooting:
 

  1. Use fresh, accurate test kit; avoid expired reagents.

  2. Adjust pH to 7.2–7.6 and TA to 80–120 ppm.

  3. Check phosphates ≤ 100 ppb, CYA 30–50 ppm.

  4. Use phosphate remover if necessary.

  5. Avoid excessive CYA (>70 ppm); dilute if needed.

  6. Retest 12–24 hours after adjustments with full circulation.

🧼 ISSUE #6: Algae Growth Persists

​Possible Causes:
 

  • Low hydrogen ion output

  • Poor circulation or dead spots

  • High phosphate levels

  • Imbalanced water chemistry

  • Insufficient runtime

  • Organic contamination

Resolution:
 

Algae should clear within 24–72 hours with proper hydrogen output and circulation. Contact support if unresolved.

Step-by-Step Troubleshooting:
 

  1. Check that display reads 11–22 and suction is present.

  2. Run unit and pump 24–48 hours continuously if algae is present.

  3. Brush all walls, corners, and steps to release algae.

  4. Use phosphate remover if levels > 100 ppb.

  5. Balance water chemistry (pH, TA, CYA).

  6. Backwash or clean filters; empty baskets.

  7. Vacuum to waste if algae is heavy.

⏲️ ISSUE #7: Timer Not Working Properly

​Possible Causes:
 

  • Incorrect programming

  • Power loss or reset

  • Not synced with pump

  • Digital timer malfunction

  • External automation conflict

  • Settings not saved

Resolution:
 

Timer should activate unit consistently once programmed. Replace or bypass timer if issues persist.

Step-by-Step Troubleshooting:
 

  1. Ensure timer has power and is not on a switched outlet.

  2. Confirm digital display is responsive and time is correct.

  3. Reprogram start/stop times, confirm AM/PM, and save.

  4. Verify no external automation system is overriding.

  5. Switch to manual ON to confirm unit runs.

  6. Inspect for moisture or loose wires inside timer housing.

🔢 ISSUE #8: Digital Monitor Display Reads “0” on Power Cord

​Possible Causes:
 

  • Acid needs to be replaced

  • Probe is damaged

  • Probe has reached end of life cycle

Resolution:
 

Algae should clear within 24–72 hours with proper hydrogen output and circulation. Contact support if unresolved.

Step-by-Step Troubleshooting:
 

  1. Check and refill acid reservoir if empty.

  2. Run pump at 2850–3000 RPM* and wait 3–5 min.

  3. Inspect probe for damage, corrosion, or buildup.

  4. Replace if older than 6 months (standard) or 12 months (small unit).

  5. Restart system and monitor for output between 11–22.

❗ ISSUE #9: Digital Monitor Reads “11–22” But Pool Is Still Cloudy or Algae Persists

​Possible Causes:
 

  • Water chemistry is out of balance

  • Phosphate levels are too high

  • Circulation dead spots

  • Not enough runtime for current conditions

  • Organic contamination

  • Dirty filters

Step-by-Step Troubleshooting:
 

  1. Test and balance pH, TA, phosphate, and CYA levels.

  2. Increase runtime to 24–48 hrs continuously.

  3. Brush all surfaces and stir dead spots.

  4. Backwash or clean filters and baskets.

  5. Evaluate pool usage, debris, or weather factors.

  6. Repeat hydrogen shock protocol and retest water.

Resolution:
 

If hydrogen is active but water stays cloudy, balance chemistry and extend runtime. Contact support if no improvement.

*60GPM=2900-3000rpm depending on what type of pump your using +most issues can be resolved with making sure you replace the acid at 150 working hrs.
 

  • 4hrs of daily runtime of unit=5weeks of acid usage(then replace).

  • 6hrs=4weeks of acid usage

  • 8hrs=3weeks of acid usage 

  • 10hrs=2weeks of acid usage (we recommend using 1gal of Acid Magic) or Testing for and using a phosphate remover.
