Cat Lift Trucks (& Caterpillar) 2EC30:
Cat 2EC30 , Code 33 returns in week

I repaired a code 33 with new transistors, pump driver board and an used logic board. The lift ran for just over a week and the code returned. One year ago we had the same code with this lift and replace the transistors, pump driver board and capacitors. Any thoughts on other possible causes? Thanks!
