Troubleshooting Table

Problem	Cause	Correction
No LEDs are illuminated on the display panel.	The power cord is not plugged in. The power cord is plugged into an outlet controlled by a switch.	Make sure that the power cord is plugged in. Plug the power cord into an outlet that is not controlled by a switch.
Water shortage light on the display.	The water supply to RO system is turned off. Water pressure to RO system is below the minimum specification (20 PSI).	Make sure that the water supply is above the minimum pressure specification (20 PSI). Visit our Water Shortage Warning Light (eflow) article for more information.
Water leak light on the display panel.	Water has been detected inside the bottom of the cabinet.	If water was spilled inside the cabinet during filter cartridge replacement, dry up the spilled water. Otherwise, locate and correct the leak. Visit our Water Leak Warning Light (eflow) article for more information.
Lights flashing on display panel and beeper sounding.	System has gone into fail-safe mode after 1 hour of continuous booster pump operation.	If flushing the system, clear the fail-safe mode. Otherwise, determine the reason for continuous pump operation before proceeding. Visit our Flushing the System (eflow) knowledge article for more information.
Water leaking from quick connect fittings for supply, product and/or drain.	Tubing not inserted all the way into fittings.	Properly insert and seat the quick connect fittings. Instructions can be found in the Owner’s Manual (pg. 7).
Water spewing from the product water faucet base.	The drain tubing is connected to the product water faucet’s air gap, which is not able to handle the flow.	Do not connect drain tubing to the RO faucet’s air gap. The drain flow rate from this system is too high for it.
Chlorine taste and/or odor in the RO product water.	The amount of chlorine in your water supply exceeds maximum limits and has destroyed the RO membrane. The prefilter is no longer removing chlorine from the water supply.	If the water supply contains more than 2.0 ppm of chlorine, additional filtering of the water supply to the RO is needed. Correct this condition before doing maintenance on the RO system. Replace the prefilter, post filter and RO membrane cartridges.
Other Taste and/or odor.	Post filter expended. Ro membrane cartridge expended. Contamination of the system.	Replace the post filter cartridge. If taste and odor persist, replace the prefilter cartridge and RO membrane cartridge. Use sanitizing procedure. Instructions for sanitizing can be found in our Sanitizing Instructions knowledge article.
System makes product water too slowly.	The water supply to the Ro system is not within specifications. Prefilter or RO membrane cartridges plugged with sediment or fouled.	Precondition the water supply as needed to conform before doing maintenance on the RO system. Replace the prefilter cartridge. If the rate does not increase, replace the postfilter cartridge and RO membrane cartridge.
High total dissolved solids (TDS) in product water.	Water supply to the RO system is not within specifications. RO membrane cartridge expended.	Precondition the water supply as needed to conform before doing maintenance on the RO system. Replace the prefilter, postfilter and RO membrane cartridges.
Water leaking from airgap opening.	The drain side of airgap tubing plugged, restricted, or incorrectly connected to drain point.	Inspect and eliminate the restriction or plug. Refer to air gap installation instructions for proper drain connection.
