Question about LG Dishwashers

Open Question

Hello, I have an LG-2120WHU and it has been making strange loud noises when washing for some time now. Then I tried running some anti-lime through a washing program and gradually, after several washes, it seemed to lessen the noise, but yesterday the dishwasher suddenly made a very loud noise and the I decided to try a special cleaning liquid from Neophos. Strangely it seemed as if the loud noises would slowly diminish, but in stead loud sqeaking noises started to appear and after I had run the dishwasher cleaning cycle with the Neophos liquid the machine suddenly made several rapid beeps and stopped with an E1 error after which it drained the dishwater. Now I can't get it to work again. What could be the problem? There doesn't seem to be any leakage of any kind, so why the E1 error? Thanks in advance for your help... Regards, René Park Triolo

How deep do you want to get into this?It sounds like the wash pump motor bearings that are worn.You can pull the unit out flip it over and wd40 the bearings in the motor or you can replace the bearings.Try to lube them first.

SOURCE: Dishwasher Making Loud High Pitched Noise.

A loud high pitch whine while running the dishwasher means that there is something caught in the chopper assembly. To get to the chopper assembly you need to take the racks out and take the pump apart from the inside of the dishwasher. The chopper assembly looks like a metal grate with holes in it. And it might not even be stuck in the grate but somewhere in the pump area due to the water being pumped out, so the best idea is to take the whole thing apart and clean everywhere. However I do not recommend doing this unless you are completely certain you will remember where the screws and gaskets go, otherwise you risk damaging your pump or house from a leak or improper installation. You have been warned.

SOURCE: LG Dishwasher making grinding noise then blinking E1 code 10 minutes later

Ive got an LG LD1204w1 model dishwasher, the grinding sound started about a week before the E1 error code and incessant dinging began. I found FixYa the best site for LG solutions, the wiring had fused to the lining on the door as suggested, so a bit of electrical tape has done the trick as far as the E1 error and dinging is concerned (thankfully no broken wires)
However I still have the grinding sound during the wash cycle. Drainage and fill hoses are to specifications stated by LG, there is no wear on inspection, the unit isnt losing water during wash so the air/water issue I dont think is relevant to my situation. Is there anything else that could possibly be causing the awful noise its making? The noise seems to be coming from the bottom/underside of the dishwasher.

Why is my LG TROMM frontloader dryer making a loud noise when running?


If the washer is making a loud noise the rear drum with bearing might need to be replaced. On this washer the bearing might not be sold separately, the entire rear drum might have to be replaced. This is a very involved repair and will require disassembling most of the washer. However, the problem is going to get worse very quickly and so either the drum and bearing will need to be replaced or the washing machine.

LOUD NOISES IN MACHINE;

LOT OF THINGS TO CHECK, THE BELT LOOSE OR WORN, THE CLUTCH, THE TRANNY, THE BEARINGS BOTH TUB SEAL AND BEARING, THE REAR DRUM BEARING,
THE DRIVE PULLEY- If the washer is making a loud noise the drive pulley might be worn out, cracked, loose or bent. Remove the drive pulley and inspect it carefully. If it is damaged or defective replace it.
THE TRANSMISSION, THE MOTOR COUPLER, THE MOTOR DRIVE BEARINGS,
THE DRIVE MOTOR- If the washer is making a loud noise the drive motor bearings may have worn out. Washer motors are normally almost silent when they run. If the motor is run without a belt hooked up to it and it's loud it will have to be replaced.

Have you check the pump, all front load washer drain before filling. If you have coins or foreign object inside pump the can be the cause of scraping noise. I would also check the tub for nails or object that can poke through and tub on the outer tub during rotation. Most of the time its a foreign object in the pump issue. Good luck..

LG dishwasher LD-2120WHU I get the


This happens to my LG dishwasher every 6 months or so. It also makes a groaning sound as if the system is starved for water. The resolve the problem by removing the dishwasher and laying it over on it's right side. I then remove the two plastic assemblies that are on the left side and I remove them from the dishwasher (you will need a vice grips to remove the hose clamps from behind them, you will also need to remove the round circular water intake plastic disk that is on the inside of your dishwasher on the left hand side right in the middle of the left wall) and clean them. Once the water can run freely through these plastic parts you will get a good water flow and you should be fine. Until you have time to do this I recommend putting a few quarts of hot water into your dishwasher once you start to hear the groaning problem. This solution should be very easy for anyone who is comfortable doing their own oil change. Oh, and turn off the power supply first.
