Welcome to our forum.
I have a 2001 Sundance Altamar 850 series hot tub that is defying my error diagnostic skills. I need help please. I know that the subject of FLOW error has been discussed many times but the problem I have is strange.Normally the flow error is caused by either clogged filters or flow switch. I replaced both the fine and coarse filters and bought a new flow switch. I still get the same FLOW error. Following an old post, I pulled out and re inserted the Sensor Loom (top middle of board) and with a click the motors stated working again as if something needed resetting but when they timed out, I got the FLOW error again.So, the filters are clean, the flow switch is new and positioned correctly, why am I still getting this error?
Thank you T Man and Pers.The Circ pump was replaced on 7/2016 and the two-speed pump replaced on 9/2016. I strongly believe in maintenance and do take care of my hot tub and water.Pers, resetting with main power off did not solve the issue. When I pull the Sensor Loom off and then plug it back in, the pumps come on and the display does not show FLOW. When the pumps are manually turned off or as they time out, FLOW raises its ugly head. Also I would hate to spend replacing the circuit board and find the problem unrelated to the board.Is there a way to test flow switch in or outside the tub?
....Also I would hate to spend replacing the circuit board and find the problem unrelated to the board....
I would not recommend replacing perfectly working equipment just because the parts are "old."
I am a pretty good handyman and will attempt any repair that's thrown at me. ...Control Pac.....is there such a thing on the market available as a bundle?
...Edited to add - if you change out the control pac you will have to reinsert the main wiring connection, and redo pump wiring connections. However, the control pad is provided with a plug in harness. I had to use a provided adapter plate for the control pad. Other than it was just a bolt-in replacement where the heater is.
