H20 error on Coyote Drifter Hot Tub
Air locks are a common occurrence after a drain and refill.
An air pocket gets trapped right in the pump volute, where the impeller is housed. So, the impeller sits in a pocket of air. It will spin there all day long, or until the cows come home, if they ever do? And you will never have water movement.
anyway, what needs to happen, is that air pocket needs to be pushed out of there! And the atmospheric pressure on the water in the tub will be your friend.
If you have isolation valves before and after your equipment, close the valve on the discharge side of the pump. Leave the suction side valve open.
loosen the union a couple of turns, on the discharge side of the pump, or one of the unions at the heater assembly, it doesn't matter which of the three.
You will get water, then the HISS of Air!
Let all the air come out, then water again, for about 3-5 seconds, then tighten. Open the closed valve. Start system. It should take off.
Good luck.
