Dead Flow Switch within 6 m

Were they visibly damaged?
Not the flow switch. It looks good. I will take my multi-meter to it tomorrow.
The temp switch: Looks like someone rocked the filter creating a space that the wire from the temp sensor slipped under. The wire was crushed and I will check for continuity tomorrow. I shut off the system. Too bad. It was off for 48 hours prior to my repair. I've never cleaned a swg. The rattle seems to be near the cord side.
 
The pressure guage on the filter seems quite low. (needle only 10% deviation from starting point) Being new at this I don't know if too low represents any issue when all else seems ok (except for the rattle I mentioned)
 
You said it James the Chinese Crud is no good we use Harwil. Their reps are nice and very knowledgeable.View attachment 553971
Thank you for this info: I now have a theory why both my temp sensor and flow sensor went at same moment. Here is the theory. I suspect the check light came on when the temp sensor cord was crushed by the scissors like effect of the filter trapping the wire beneath the cement below and the base of the filter. Leaning against the filter allows just enough space for the cord to slip under it if kicked or something. I believe in the process of checking out the problem of the lit check light , the tech probably turned off or turned down the variable speed motor. The reason I believe this is (1) I found the crushed temp wire under the filter base and (2) after replacing the wire and after replacing the flow sensor the pump did not start. The pump did not start despite all check lights being off and the filter light and the pool lights were lit on the PS-8. When i manually turned on pump all was well. . I suspect that if I put my old flow switch back in, it would work. But I am not going to bother as they are temporary until I get quality ones.
