Can someone please tell me how to manually put the machine through the online PHT test. I have a 2008k machine. Thanks in advance.

Ok, I got the machine to manually go into online PHT test. It passed the first couple times, as well as both alarm and pressure test and diasafe test. I have already replaced the diasafe because it was due 10/12. Dear pressure is -24, loading is +24. Now I have an intermintent high flow error, and the third time it did fail online PHT. On the valve test, all valves passes. Any suggestions????

If anybody has any suggestions, I would be very grateful. I plan on working on the machine tomorrow. Also temp and coonductivity have been calibrated with no problems

Online PHT failures are associated with valves 24, 25, and 26
It is one of those three valves that is failing.

I just fixed my pht problem and could visibly see it was valve 25 leaking. easy to notice for me but i would check those 3 valves first.. good luck
