TROUBLESHOOTING
Problem H
No Flow light on
CAUSE1: Insufficient water flow through the cell.
REMEDY:
Ensure sufficient water flow through chlorinator cell. Verify that the filter and pump 
are on. Flow may be restricted if the filter needs backwashing. A pocket of air 
trapped in the top of the cell confirms low water flow through the cell.
WARNING: Operating Clearwater Salt Chlorinator LM2 without water flow through 
the cell can cause a build up of flammable gases which can result in 
FIRE OR EXPLOSION.
CAUSE 2: Sensor disconnected.
REMEDY:
Make sure that the sensor lead from the power pack to the cell is attached at the cell 
(small clip lead).
Problem I
Chlorinator stops working, all lights OFF
CAUSE 1: Unit turned off.
REMEDY:
Push ON/Off button. A yellow light in the ‘Chlorine Output’ indicator window is 
present when the unit is on.
CAUSE 2: Mains power removed or blown fuse.
REMEDY:
Check mains power source and fuse.
Resetting the Fuse
Turn off all power to the Clearwater power pack. The resettable fuse is located 
above the power cord on the bottom rear of the unit. If the fuse is blown (popped 
with white area exposed), push to reset. Restore power to unit.
Mains power supply
Your Clearwater chlorinator must be connected to a properly grounded electrical 
power socket, or power source.
