I have two K2 machines (approx. 38K hours) that run spectacular in Dialysis mode. During the heat cycle it runs as it should... up until about 7 minutes left until the end of the cycle. Then it throws a Flow Recirc 1 error.
Pumps pressures. Checked and good
Valve 24, 25, 26, 27/41, 29 & 39... Checked and rebuilt. The valves all ohm out good while cool. Would it be worth ohming when the valves are warm? If I run the valve leak test at the start up it all passes. When I attempt the valve leak test when the recirc error happens, it fails ISO.
I have seen the IC chip 26 burn up on the actuator board cause this problem on a few occasions but the error would show as soon as the rinse portion of the heat cycle is completed and transitions to the heat cycle. That tells me I am not dealing with a board issue.
I know that was a mouthful, but at this point I am just baffled.
