Arctic Spas Pulsing Water Pressure

[DigitalMan]

So I've noticed lately when I have pump 1 on high (ie pressing Pump 1 twice) the water pressure pulsates. Is this air trapped or something worse?

There could be something wrong with the pump itself, but I would check a few simple things first. Make sure your water isn't too low. Even if you think it isn't too low, maybe add a little bit of water to the spa. If the water gets too low, it can cause surging at the filter canister, which will cause the pump to cavitate and cause the pulsation you are describing as well. When the water gets topped off, it should stop that if the water was too low. Also, clean/and or replace your filter if it has been a while since you have done either of those. Check those things and report back if that doesn't.

Well thank you very much. Although the water appeared to be down only about 1/2 inch once I topped it up the pulsating stopped.

Thanks again.

Good deal! Glad to hear it is working good again!

My tub just started this and the water levels are high, like topped right up and I haven’t changed the water in a month! So why is this happening to me is it the pump then?  It pulsates and then stops for a minute and then starts again!
