Flow Sensor with Cable
The flow sensor uses a magnetic reed switch and a hinged paddle to detect water movement. Over time, the magnetic hinge can become fouled by calcium deposits or the internal reed switch can fail, causing the system to provide a false 'low flow' signal to the control board even when the pump is physically moving water.

Intake Strainer Grid
This is the primary physical filter on the suction side of the system. Ingress of organic debris like grass or leaves clogs the grid apertures, significantly increasing vacuum pressure and reducing the mass flow rate below the threshold required to actuate the flow switch paddle.

L-Shape O-Ring and Seal Kit
The flow switch relies on a pressurized, air-free stream to maintain consistent paddle displacement. Degraded seals on the strainer housing or hose connections allow atmospheric air to enter the suction side (cavitation), creating air pockets that cause the flow switch to fluctuate and trigger Error 90.
