LDPN454HT (ASSESNA) 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!

The inside gasket deteriorates over time - However replacement is easy. the main thing you have to remember is after you remove the old gasket, install the new one starting at the middle top of the tub and work your way down both sides. Also, don't push the gasket all the way in...only enough to hold in place. When you close the door the gasket will form a better seal around the door.

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.

Ordered the top rack only. had to install all the other parts that were attached to the rack. The adjustment handles were the hardest to install b/c you need to take them apart and they have springs that support the adjustment buttons. It took me about 2 hours to remove and reinstall the handles......they were a pain to work with. I would recommend purchasing the complete top rack that has the complete rack that you just need to remove the bad one from the tracks and replace with the new one.

Saw a YouTube video that explained the problem was the pump. Removed dishwasher from under the counter, flipped it on its side, and unplugged the unit. Removed bottom cover and the pump is right there. Used pliers to lose and move 3 hose clamps. Unplugged 3 wires and unscrewed the ground. Unhooked rubber hold downs and removed. Installed new pump. Parts Select pricing was best I found and shipping was fast. Nice to have a quiet house again when running the dishwasher. Cost in total was less than $100.

I am 77 years old and got it all on but the corners did not want to go in so I had to call my grandson and he got them in. It still leaked on the bottom left side. It is getting old (11 yrs) so I decided to get a new one. It is actually pretty simple to install, but it does take a little strength.

Snapped the rollers on.

Took off the broken one and snap on the new one.

The parts are wrong and am trying to return them. There was no return information included with delivery. Calling the Customer Service number for assistance did not work.

I would just like to return these rollers and would like a return address.

Thank you!

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.

I ordered four wheels to replace the two that were broken and to have two as spares. The wheels are to be snapped onto the bottom of the lower basket. The new wheels broke upon being installed. My extra wheels came in handy. I put them in very hot water for a few minutes to soften the plastic. I put a little Vaseline on the post they were to be attached to. The wheels then slid on and snapped correctly.

Snap off old broken holder . Snap new holders in. No issues.

Took a picture of damaged part and searched internet. Found exact match at partsselect.com. Received parts in a reasonable amount of time. Snapped parts into place. Job complete.

snapped on new axel-wheel assembly

The replacement racks fit perfectly and my wife doesn't use the vertical adjustment feature on the top rack so I didn't need to transfer it from the old rusted rack to the new one.
When I cleaned the filter there was alot of rust flakes. I'm thinking about pitting a rare earth super magnet in the filter basket to keep the flakes away from the water pump impellar and pump seals. I also created a corrosion anode by wrapping aluminum foil around a tennis ball and putting it in the rack utensils holder. When the foil turns black I replace it.

Thanks partselect to the MAX.
