Low Pressure reading; also low salt reading

They may be related?

Pump and Skimmer baskets clear--no bubbles out of the return--I do the pressure gauge rotate--water comes out in about 1 second. Shut off the main drain still low pressure. There is a small occasional drip from the backwash line.

Aqua-Rite salt level reads 2300-2600--then I recalibrate doing the switch flip and it reads -3100. Drip tested and the lowest reading I got was 3200.

When pump was running 24/7 the salt readings were fine, but when I use the timer, I have to recalibrate every morning.

Is it possible my multi-port valve is malfunctioning and the low flow is messing with the SWG unit?

Does your SWCG completely power down when the pump is not running? It needs to be connected to the same timer as the pump.
