BRAND NEW maxi jet burnt out

[rusty shackleford]

j&l replaced the pump, no questions asked.
i cant say im 100% sure nothing got into it, but its in a section of my sump with no snails, sand only thing in that section is my skimmer.
and my over flow box has a filter sponge on it, never see any solids in there.
i didnt think restricted flow could do it either, i thought it was more likely it burnt out the motor

sisters bringing the new one out tomorrow and ill give it a try again, hopfully there will be no issues but im never gonna have full confidence in it after the first POS crapped out.
