What to do if Whale orca auto 1300 runs but does not pump water / pulses?

If your Whale Water Pump runs but doesn't pump water or pulses, it might be due to a blockage or airlock in the hose. Clear any blockages and make sure the outlet hose runs upward to the thru-hull connector without any dips. Another reason could be a restricted impeller. In this case, remove the pump housing from the base, clear any debris from the chamber and impeller, and ensure the impeller is firmly attached to the shaft and isn't cracked or broken.
