ELECTRONIC DIAGNOSTICS

The faceplate has a self-diagnostic function for the electrical system (except input power). The faceplate monitors electronic components and circuits for correct operation. If a malfunction occurs, an error code appears in the faceplate display.

The Error Code Chart shows the error codes that could appear, and the possible defects for each code.

While an error code appears in the display, all faceplate buttons are inoperable except the SET button. SET remains operational so the service person can perform the Manual Advance Diagnostics below to further isolate the defect.

Electronic Diagnostic Error Codes

Problem:
Error code E1, E2, E3 or E4 appears.

	POSSIBLE CAUSES	SOLUTIONS	REPAIR KIT(S) NEEDED
1.	Wiring harness or connection to position switch.	Replace wiring harness or connection to position switch.	Motor/Switch Kit
2.	Switch.	Replace switch.	Motor/Switch Kit
3.	Valve defect causing high torque.	Replace rotor seal.	Rotor/Seal Kit
4.	Motor inoperative.	Replace motor.	Rotor/Seal Kit

Procedure for removing error code from faceplate:

1. Unplug transformer
2. Correct defect
3. Plug in transformer.
4. Wait for 6 minutes.

The error code will return if the defect was not corrected. Press and hold the VAC/RCHG button for 3 seconds as an alternative way to clear an error code.

Problem:
Error code E5 appears.

	POSSIBLE CAUSES	SOLUTIONS	REPAIR KIT(S) NEEDED
1.	Faceplate.	Replace electronic control board.	Electronic Control Board Kit

Procedure for removing error code from faceplate:

1. Unplug transformer
2. Correct defect
3. Plug in transformer.
4. Wait for 6 minutes.

The error code will return if the defect was not corrected. Press and hold the VAC/RCHG button for 3 seconds as an alternative way to clear an error code.

Manual Diagnostics

• Press and hold the (Set / Clear) button for 3 seconds until 18:88 shows in the display.

• Press the (Recharge Day) button to display the position switch open or closed indicator.
• The letter P and a dash or dashes indicate position switch operation. The letter shows if the switch is closed. A dash shows when the switch is open.

NOTE: The position switch is closed when the plunger is depressed, open when extended.

CORRECT SWITCH DISPLAYS	VALVE CYCLE STATUS
- -	Valve in soft water, backwash or fast rinse position.
- P	Valve rotating from one position to another.

To enter FILL cycle, press and hold the (VAC/RCHG) button for 3 seconds to start the motor.

• If the motor does not run, check the motor and all wiring connections.
• Check for fill water flow to the salt storage tank. If water does not enter the tank, look for an, obstructed nozzle and venturi fill flow plug or brine tubing.

After verifying fill, press the (VAC/RCHG) button to move the valve into brining (if the DOUBLE BACKWASH option is set, the valve will enter backwash and fast rinse before brining). A slow flow of water to the drain will begin. Verify brine draw from the brine tank by shining the flashlight into the brinewell and observing a noticeable drop in the liquid level after several minutes. Remove brine lline from the nozzle and venturi by loosening the ferrule nut. Place a finger on the nozzle and venturi opening and feel for suction.

NOTE: Be sure water is in contact with the salt, and not seperated by a salt bridge.

• If the unit does not draw brine, check for (most likely to least likely):

  • Dirty or defective nozzle and venturi.
  • Nozzle and venturi not seated on the gasket, or gasket defective.
  • Restriction in valve drain, causing a back-pressure (bends, kinks, elevated too high, etc.).
  • Obstruction in brine valve or brine tubing.
  • Inner valve failure (obstructed outlet disc, wave washer defective, etc.).

Again press the (VAC/RCHG) button to move the valve into backwash. Look for a fast flow of water from the drain hose.

If flow is slow, check for a plugged drain hose, backwash flow plug or top distributor.

• Press the (VAC/RCHG) button to move the valve into fast rinse position. Again, look for a fast flow of water from the drain hose. Allow the unit to rinse for several minutes to flush out any brine that may remain from the brining cycle test.
• To return the valve to soft water position, press the (VAC/RCHG) button once again.
• Press the (Recharge Day) button to display 18:88.
• Press the (Set / Clear) button to return the present time.
