Two cutler –hammer advantage starters are doing the same thing:
. \& r3 i6 U/ _$ { After start 2-3 times, they will quit working, if you toggle the start and stop buttons on DCS screen , you will get another 2-3 running before they quit working again. 5 q. P( X( u0 ]8 B& s7 ?% v- C
It is a cycle.

The problem should be inside the bucket.

Use a terminating screw divers to push in the contactor, it will not seal either.1 F$ O! Z. n/ W4 X1 L; S
Confirm with TECH support this should be a problem with the control circuit board inside the advantage starter, we bought two new control circuit boards and replaced the old ones, the problem is still the same.1 T. c- S% z' U/ U
