Circuit Board Troubleshooting

Most circuit board problems are caused by outside influences and it is not the board itself. Replacing the board may seem to work

only because the cause hasn’t been reproduced.

Let’s start with what to check when you come upon a circuit board problem:

1. Are those switches aligned too far away to the cam?

There should be a small as possible gap between the switches and the cam so that a “wobbling cam” doesn’t accidentally open

the switch.

2. Has the seal pack been checked for free movement?

Feedback and experience has demonstrated that seal packs that are over-tightened create drag on the motor and delays that

would result in an error code: If the motor never stops (still runs after the desired position is sensed, causing unexpected

switch closures) OR if the motor gets stuck “timing out” and the control never sees any switch action.

3. Are all the wiring terminals tightly connected?

Sometimes a loose or poorly connected wire can give feedback to the board that would result in an error code or default.

4. After checking all of these possibilities you should run the diagnostics (test mode) on the board.

Listed below are some other rare circuit board behaviors and their explanations:

Board skips the service position or only stops for a second in service before advancing to the backwash position

Board has been armed for regeneration. Let the board time out of the last cycle OR reset and reprogram the board.

Motor goes round and round

Only one of two things can happen when this is the case; it can find its desired position or it gives you an error code. So, LET IT

RUN until you find out which will occur.

• If the motor still runs or there is power to motor after the error code is displayed, then the triac is likely bad – change the

board.

• If the error code is displayed and the motor is stopped (no power to the motor), check switches, cam and wire harness

– the board got a signal it wasn’t supposed to or a connection failed.

The board repeatedly defaults, resets or gains time

Look at the power supply or source. Most of these issues are caused by the power source, so-called “dirty power” having noise

interference or incorrect voltage. This could be erratic fluctuations caused by other heavy power draws, poor wiring, low voltage

wiring running along high voltage, having active electrical storms that causes “corruption” of the EEPROM. Consider the use of a

surge protector or an uninterruptible power supply after you see this repeatedly.

If you suspect the power source is causing problems, take a voltage reading at the outlet, at the power connection on the board,

and on the motor leads while the motor is running. We are looking for a consistent range of 108-132 volts at the receptacle and 22-

28 volts on the board. Also, the wall transformer is only used to step down the voltage; it is not used for protection or filtering the

power source.
