Product review (5 stars): DIY and save versus replacing your dishwasher
Our LG dishwasher failed after 5 years and was out of warranty.  There was an error code for the motor which was a result of a pin hole leak in the gasket and a sappy liquid that eventually dripped into the motor.  The cost to replace the dishwasher was around $1,000.  A new motor from Sears and some online parts suppliers was around $200 just for the motor.  This unit is the entire guts of the dishwasher.  The hardest part of the repair was removing and re-installing the dishwasher.  The replacement pump and motor was easy.  I used a turkey baster to remove the standing water in the tub and removed the unit from the cabinet.  There are only 2 screws holding in the pump and motor assembly.  I marked the wires and took some digital photos before I disconnected everything.  The new unit popped right in.  Works like a charm.  Can't beat the price.  For $116 plus my own labor I essentially have a new dishwasher.  If you are reasonably handy, this is an easy job.  Like I said, worst part was removing the unit to get access underneath.  Have some towels handy as there will be some residual water when you tilt it on it's side.
