How do I replace dishwasher door hinge spring?

SOURCE: LG dishwasher model lds5811st error

per instructions in other's posts, I removed door panel, but no wires broken, so called LG and local authorized LG repair and they tell me motor sub-assembly needs replacement, cost $160 for parts, $200 for labor, which is making a new dishwasher look attractive.

There is no adjustment to the door hinges. If your hinges are failing they will need to be replaced.

hi
The most common cause of an OE error code on a modern LG dishwasher is:
1. Blocked drain hose
2. Obstruction in the sump area (beneath the filter, which needs to be removed to check for onstruction)
3. Failing drain motor. 
else you need to REPLACE THE PCB POWER CONTROL BOARD
