  If your Franklin Electric Water Pump doesn't start when the tank is full, it could be due to several reasons. The pump may not be connected to electrical power; ensure it is connected to a dedicated GFCI circuit. The circuit breaker might be off, or the fuse removed; turn on the circuit breaker or replace the fuse. Debris accumulation on the float can also cause this issue; clean the float. Check for any obstructions in the float movement path and remove them. In some cases, a defective switch or motor may be the cause, requiring pump replacement.

  If your Franklin Electric Water Pump won't shut off, there are a few potential causes. Check for any obstructions in the float movement path and remove any debris. It's also possible that the liquid inflow matches or exceeds the pump's output capacity, requiring a larger pump. In this case, the high level switch should shut off the A/C unit or signal an alarm if connected in the circuit correctly. A defective switch may also be the reason, requiring pump replacement.

  If your Franklin Electric Water Pump runs but doesn't discharge liquid, the check valve might be stuck or plugged; remove the check valve and inspect for proper operation. The lift may be too high for the pump; check the rated pump performance. The inlet to the impeller could be plugged; pull the pump and clean it. Also, the outlet flow may be obstructed; check the outlet tubing to ensure that it is not kinked or blocked, clear blocked tubing of slime and debris, and clean the inlet and outlet piping.

  If your Franklin Electric Water Pump isn't delivering its rated capacity, it could be due to a few reasons. The check valve might be stuck or plugged; remove it and inspect its operation. The lift might be too high for the pump; check the rated pump performance. Low voltage could also be the issue; check that the supply voltage matches the nameplate rating. Additionally, the impeller or discharge pipe might be clogged; pull the pump and clean it, and check the pipe for scale or corrosion.
