NO SOFT WATER – Most Common Problems:

Check the following before calling for service:

•Not enough salt—brine tank should be at least 1/3 full.

•Bypass valve in “Bypass” position—flange on knobs should be in line with pipes (see page 6).

•Hardness setting too low. Check hardness setting and adjust. Verify hardness of supply water—from local water company, water test or call the GE Answer Center.

•Salt Bridge—salt solidifies above water level so that brine water is not in contact with salt. See the Breaking a Salt Bridge section.

Problem Possible Causes What To Do

No soft water	Faucet or fixture where sample was
	taken not plumbed to soft water.
	NOTE: Be sure sample is from a faucet
	that does not mix soft and hard water.
	For example, a single lever kitchen faucet,
	if the cold side is plumbed to hard water.

•To conserve salt, the installer may have isolated some fixtures (outside faucets, toilets, etc.) from soft water. From the outlet of the water softening system, trace the water flow path, in house plumbing. If soft water is not directed to a faucet or fixture where wanted, consult a plumber.

No salt in the brine tank or salt bridged

•Check for a salt bridge or, if the tank is empty, refill with recommended salt. Press (for 3 seconds) the REGEN button to start an immediate regeneration and restore soft water supply. See page 17, Breaking a Salt Bridge.

Transformer unplugged at wall outlet or power cable to softener not connected. Fuse blown or circuit breaker popped on circuit to electrical outlet.

Electrical outlet on a circuit that can continuously be switched off

•Check for a loss of electrical power to the water softening system, due to any of these conditions and correct as needed. With the power supply restored, observe the faceplate time display and read Programming the Control section.

NOTE: The electrical outlet for the softener should be live so it cannot be accidentally switched off.

Manual bypass valve in bypass position • Be sure the flange on the bypass valve knobs are in line with the pipes.

Valve drain hose pinched, plugged, elevated too high or otherwise restricted

•Any restriction in this drain hose may prevent proper operation of the nozzle and venturi and reduce or prevent brine draw during regeneration.

Injector and injector screen dirty, incorrectly assembled or damaged

•This will be evident by a high level of water in the brine tank. Water level will be greater than 4″ when the system is in the service position.

•Refer to Cleaning the Injector and Screen instructions.

With water pressure to the water softening system off, remove the injector and injector screen. Thoroughly clean and flush. Check for any damage. Reassemble to valve assembly.

If resin bed is fully exhausted, for example, after a malfunction, one regeneration cycle may not fully restore capacity

•Complete “back to back” regenerations. Initiate Regeneration cycle, wait 1 minute, then press REGEN again.
