Pool pump question

[Dima]

Good day, I have 1HP HAWARD pump and I noticed the water flow is really bad . Pump been running for a 2 years in my above ground pool. Couple of weeks ago, my kid was able to manage let it run dry for about an hour. Would that can caus the damage to it ? I can understand it it does not work at all, but it looks like working but not enough flow compare what it used to be. Or maybe should I look at something else ?

Thanks!

Have you checked your filter pressure? When was the last time your backwashed the filter? Does the water return have air bubbles in it?

No air bubbles. How do I check filter pressure ? I usually backwash once a month. Should I just open Sand Filter and check it out ?

Your sand filter does not have a pressure gauge on it? It should.

Thank you it looks it started to work. Appears I was using Rinse option of the filter instead of backwash. I just switched to backwash for a minute and water flow increased as it should be. Will buy pressure gauge now. Thanks again!
