Navigating the display usually involves a combination of buttons – often labeled ‘Menu,’ ‘Select,’ and ‘Up/Down arrows․’ These buttons allow you to access and modify programming parameters such as regeneration time, salt dosage, and water usage settings․ Pay close attention to the icons displayed, as they represent specific functions or conditions․ A flashing icon often indicates an active process or a potential issue requiring attention․
Understanding the display’s language is key to proactive maintenance and troubleshooting․ Regularly checking the display can help identify potential problems before they escalate, ensuring consistent water quality and extending the lifespan of your Fleck 5600 system․
Basic Programming: Time Clock & Regeneration
Setting the correct time is the foundational step in Fleck 5600 programming, ensuring accurate regeneration cycles․ Access the ‘Time Clock’ setting via the ‘Menu’ button and use the ‘Up/Down’ arrows to adjust the hour and minute․ Confirm your changes using the ‘Select’ button․
Regeneration programming dictates when the system cleans itself․ The most common method is ‘Timeclock Regeneration,’ where you set a specific time for regeneration – typically during low water usage hours (e․g․, 2:00 AM)․ Alternatively, ‘Demand Regeneration’ initiates a cycle based on water usage․
To program regeneration time, navigate to the ‘Regeneration’ settings in the menu․ Input your desired time and frequency․ Proper programming optimizes salt consumption and maintains consistent water softening performance․ Regularly review these settings to adapt to changing water usage patterns․
Advanced Programming: Customization Options
Beyond basic settings, the Fleck 5600 offers extensive customization․ ‘Backwash Time’ adjusts the duration of the backwash cycle, impacting cleaning efficiency․ ‘Brine Draw Time’ controls how long the system draws brine from the tank, influencing salt usage․ ‘Fast Rinse Time’ determines the rinse duration after backwash․
‘Slow Rinse Volume’ is crucial for resin bed compaction, ensuring optimal performance․ Adjusting ‘Brine Refill Volume’ fine-tunes the amount of water used to replenish the brine tank․ Explore ‘Salt Dosage’ settings to precisely control salt consumption based on water hardness․
Experienced users can modify ‘Regeneration Delay’ to postpone cycles under specific conditions․ Remember to document all changes for easy reversion if needed․ Incorrect adjustments can affect water quality and system efficiency; consult a professional if unsure․
Regeneration Cycle Explained
The Fleck 5600’s regeneration cycle restores the resin’s ion exchange capacity․ It begins with ‘Backwash’, removing accumulated sediment and debris․ Next, ‘Brine Draw’ pulls salt-rich brine from the tank, replenishing the resin with sodium ions․ ‘Slow Rinse’ carefully compacts the resin bed, optimizing performance․
‘Fast Rinse’ then flushes remaining brine and loose particles to drain․ Finally, the system returns to service, providing softened water․ Cycle duration depends on settings and water hardness․ Monitoring brine tank levels is crucial for consistent regeneration․
Understanding each stage ensures optimal system function․ Irregular cycles can indicate issues with valve operation or brine supply․ Proper regeneration maintains water quality and extends resin life․ Regular checks and adjustments are key to long-term efficiency․

Maintenance and Troubleshooting
Regular maintenance ensures peak performance․ This section covers filter replacements, brine tank care, error code resolution, and addressing low water pressure issues effectively․
Filter Replacement Procedures
Replacing the filter media in your Fleck 5600 is crucial for maintaining water quality․ Begin by shutting off the water supply to the system and bypassing the valve if necessary․ Carefully remove the control valve head, noting the position of the riser tube and any internal components;
Slowly extract the old filter media – gravel, sand, or resin – ensuring minimal disturbance to prevent media from entering the plumbing․ Thoroughly clean the filter tank, removing any accumulated sediment or debris․ Inspect the underbed collector for damage and replace if needed․
Refill the tank with the appropriate media, following the manufacturer’s recommended fill levels and layering sequence․ Reinstall the riser tube and control valve head, ensuring a secure and watertight seal․ Restore the water supply and initiate a slow backwash cycle to settle the new media before normal operation․ Always consult the full manual for specific media types and procedures․
Brine Tank Maintenance
Regular brine tank maintenance is essential for efficient regeneration․ Periodically, typically every few months, inspect the brine tank for salt bridging – a hard crust forming on the salt surface․ Break up any bridges with a tool, ensuring salt can freely dissolve․ Remove any debris, such as sand or sediment, that accumulates in the tank bottom, as this reduces brine capacity․
Clean the brine tank thoroughly at least once a year, using warm water and a mild detergent․ Avoid harsh chemicals that could contaminate the water supply․ Check the brine well and float valve for proper operation; ensure the float moves freely and the well isn’t clogged․
Verify the brine line isn’t kinked or blocked, allowing unrestricted brine flow to the resin tank․ Maintaining a clean and functional brine tank optimizes system performance and extends the life of the resin bed․
Common Error Codes and Solutions
The Fleck 5600 control valve displays error codes to indicate system malfunctions․ A “Low Salt” error signals insufficient salt in the brine tank; replenish the salt level immediately․ “Brine Draw Error” suggests a problem with the brine line or well – inspect for blockages or kinks․ “Regeneration Error” indicates an issue during the regeneration cycle; check the motor assembly and valve operation․
“Flow Error” often points to low inlet water pressure or a restricted flow path; verify adequate pressure and inspect for obstructions․ If a “Bypass Valve Error” appears, ensure the bypass valve is fully open or closed, not partially engaged․ Consult the full error code list in the manual for detailed explanations․
For persistent errors, power cycle the valve or contact a qualified water treatment professional for assistance․ Addressing error codes promptly prevents further damage and maintains water quality․
Troubleshooting Low Water Pressure
Low water pressure can significantly impact the Fleck 5600’s performance․ First, verify that the main water supply to your home is adequate․ Check for partially closed valves upstream of the water softener․ Inspect the inlet screen within the control valve housing for sediment buildup; clean it thoroughly if necessary․
A clogged filter media bed can also restrict flow; schedule a backwash regeneration cycle․ Examine the plumbing connections for kinks or obstructions․ Ensure the bypass valve is fully open, allowing water to flow through the system․ If pressure remains low, investigate potential issues with your well pump or municipal water supply․
Consider a professional pressure test to pinpoint the source of the problem․ Addressing low pressure ensures optimal softening and extends the lifespan of your Fleck 5600 system․
