LDT5678ST LG Dishwasher - Instructions

Replacing this pump is pretty easy. Disconnect the power and drain hose, and pull your dishwasher out from the counter. Lay it on its side on a towel. There WILL be spillage. Disconnecting the pump is simple. There are a couple hoses, one single wire connection (the thermistor) and one multi-wire plug. The pump is held in place by a pair of thick rubber holders which can be pulled off by hand. That's it!

After removing the pump, I disassembled it to find out why these fail so soon. It's a very poor design. I found that the nose of the electric motor, where the bearings are located, sits in a plastic cup formed by the top of the pump body. Any leakage from the pump around the motor shaft will be held in place against the motor bearing. It has no place to go. This causes rusting of the bearing. I expect I'll be replacing this one in a few years. :(

But kudos to PartsSelect for getting the right pump assembly for me, after getting the wrong one from another supplier!

This was my first time repairing a dishwasher. I watched YouTube on how to remove the dishwasher from the cabinet. Afterwards, I removed the bottom of the dishwasher while it was laying flat to get to the motor and micro switch. The only difficulty I had was getting to the motor which required taking the bottom section off of the dishwasher. I could not get an appliance repair company to work on an LG dishwasher. My only option was to repair the dishwasher or bought a new dishwasher. Therefore, my wife and I decided to , make an attempt to repair this one with a backup plan of buying a new one. Luckily, we were able to fix this one within two hours.

This was a $999 dishwasher. We saved the cost of a new dishwasher by taking the time to fix this one.

Ordered the roller from Parts Select, slid the roller over the little spindle sticking out of the bottom rack and snapped it in place. Job done in less than one minute.

Was not able to see where the Stopper, Rollers ( Part # PS3523062) could be attached to the back of the bottom tray, to fix the problem. So the parts were useless.

you need to carefully apply a little pressure to the rail moving it back towards the back of the tub, this will let it unhook from the tub, then just slide the new rail into place.
