What does 'Optical Sensor Undesired change detected by the Optical Sensor' mean on my MARLO NXT2?
If your MARLO Water Dispenser displays 'Optical Sensor Undesired change detected by the Optical Sensor', it means that the motor is off but additional encoder pulses are detected. To resolve this, trigger a manual regeneration.
What does 'Over-Current Motor Over-Current is Detected' mean on my MARLO NXT2?
If your MARLO Water Dispenser displays 'Over-Current Motor Over-Current is Detected', it indicates that the motor current exceeds thresholds. To resolve this, trigger a manual regeneration.
What does 'Motor Run-On No CAM Switch Change Detected' mean on my MARLO Water Dispenser?
If your MARLO Water Dispenser shows 'Motor Run-On No CAM Switch Change Detected', it means that the motor is on but no encoder pulses are detected or CAM Switches change state within a given duration. Verify correct valve type is chosen and trigger a manual regeneration.
Why is my MARLO Water Dispenser softener failing to draw brine?
If your MARLO Water Dispenser softener fails to draw brine, it could be due to a plugged drain line flow control (clean it), a plugged injector (clean it), a plugged injector screen (clean the screen), line pressure being too low (increase line pressure to 20 P.S.I), an internal control leak (change seals, spacers, and piston assembly), or the service adapter not cycling (check drive motor and switches).
What causes excessive water in the brine tank of my MARLO Water Dispenser?
Excessive water in the brine tank of your MARLO Water Dispenser can be caused by a plugged drain line flow control (clean flow control), a plugged injector system (clean injector and screen), the timer not cycling (replace timer), foreign material in the brine valve (replace brine valve seat and clean valve), or foreign material in the brine line flow control (clean brine line flow control).
Why does the drain of my MARLO NXT2 Water Dispenser flow continuously?
If the drain of your MARLO Water Dispenser flows continuously, it could be due to several reasons: the valve is not programming correctly (check timer program and positioning of control, replace power head assembly if not positioning properly), foreign material in the control (remove power head assembly and inspect bore, remove foreign material and check control in various regeneration positions), or an internal control leak (replace seals and piston assembly).
