I have a flow recirc error 1 during heat disinfect. I replaced Dear Motor, & brushes on the flow motor but still getting flow recirc error 1. Troubleshooting guide recommended checks but they all passed them. Could it be a valve issue, heat exchanger or actuator board issue.
Thanks

I usually see V29 the culprit for that.

do you have flow at the flow indicator when you get the error ? check v24 if not

I went through the entire troubleshooting guide and I didn't seem to fail any of the test they told me to run. All pressures are normal. NO valve errors. I got this error before when replacing brushes and just moving tubes around deaeration clears it. I'm assuming it might be valve 29 or a kink somewhere in the system.

need some more info ... what kind of machine and hours helps and does the error happen when you first put into heat or during the circulation phase ? physically open the valve solenoid see if the plunger assembly is locked up (rusted closed )

2008T Fresenius machine no bibag, 25,141 for hours. Brushes were done last year but once I got the error I decided to replace the brushes on both motors. It takes about 8-10 seconds before it goes into an error. The remaining rinse time is 0:00 so it doesn't even run a rinse.

Motor brushes are seated? motors turning full speed? vent tubing kinked? Deair restrictor open?

Are the motors running CCW?

NO luck on the valve 29 or 24 replacements. Any idea where to look for a kink in the system.

Ended up being the entire flow & deration pump that's both went bad.

Was it the pump heads that were bad or the complete assemblies?
