Hello, I have a skimz SK181 for a while now and am very happy with its performance. Recently I have noticed a strange behavior in term of current draw. I have it plugged in an EB8 and usually the amp reading for that EB8 is averaged around 2A. Then suddenly it will jump to 2.5A and stay there until I restart the skimmer. The same thing will cycle again after the skimmer has been running for a week or two. Is it time to replace the pump of the skimmer? The pump is rated for 18W so technically the max current draw should be ~ 1.5A. Right now its only using 0.5A according to the EB8. When total current draw jumps to 2.5A, the skimmer is still using only 1A. I just dont understand why the jump and a restart will fix it. I appreciate all the helps!
