Is your spacing correct? If let's say you have a 1/4" glass and your spacer is set for a 5/8" you will burn them out. Check your spacing. Also, it's unnecessary to have your pump at 100% jmo.
Frank looks like you were right!
everybody should check spacing on dry side...these things to expensive to be changing all. the time it's 75 plus shipping and tax. 100 bucks.
They said to put to 3/8 to play on safer side. That way no stress. They also said some dry side are stronger than others which us why is caused my problem.
I had same issue and they replace them with no questions asked, the best customer service ever, including the circuit board they replaced once already. My concern is when I have no warranty what they are going to do. Time will tell
