I have a 2001 Dimension One Chairman that has 3 blinking lights and a message to clean filters and reset. I have replaced the filters and still have the message. Any ideas of what would cause the message to be displayed and the blinking lights. I see it suggests to call for service if this doesn't fix the problem. I am trying to avoid this and it is getting cold here. I am not sure if I have reset the system properly any help would be great.

Thanks

To reset the tub, turn the power off at the breaker for about 10 seconds and then turn back on.

Does the error show up as soon as it resets or does it behave normally for a few seconds? Try disconnecting the flow/pressure with the error on and see what difference it makes. If you have a volt meter handy, test continuity on the flow switch line to be sure it is closed when the pump is on, open if the pump is off.
