Lg dishwasher LDF model one week old makes a lot of noise

When first cycle runs sometimes it sounds like a moaning noise but not every time we use it. the display on the top has the 2H displayed but this is not in the owners book? almost sounds like its trying to overcome something or is not getting enough water?? any ideas

    Your help and response are apreciated, I think the 2H is the time as you said since once the cycles begin it changes to digets and counts down, the washer is only 2 weeks old and when I installed it I replaced the shitoff valve (brass sing lever) and the ss braided supply hose. I did notice that the last time we ran it we used the heavy duty/power scrub cycle and sani mode when this was noticed so I am now trying a normal cycle no sani to see if there is a diff. Hard to tell because it seems only to happen during the very first cycle for the most part . Any ideas please advise and I can respond.

Not real sure about the 2H display , I'm inclined to believe it is showing the estimated time for the cycle. As far as the noise, I believe you are on the right track with the water theory, but without hearing it myself I'm not real sure. If it is in the very beginning of the cycle most dishwashers start the cycle with a drain or initial pump out cycle. This is designed to remove any leftover water etc from any previous cycle. Depending on how much water is left over it can make different sounds at the beginning of the cycle. If you have had the unit installed for a while, depending on water conditions(hardness,sediment silt etc.) it is possible that the screen on the inlet valve is clogged or your house water pressure to the valve may not be high enough to completely open the valve. It can be a little tricky to check these yourself, but you would have to turn off the water to the dishwasher check the screen in the valve and then check to see if you have enough water pressure and volume . If you have times when your water pressure might be lower(like when I am filling our koi pond at my house) the water pressure in the rest of my house is lower. At those times it might make some wierd noises while it is filling or might not fill to the proper level. I think I would check on those things before digging into disconnecting water lines and checking screens and stuff. Good Luck and reply back if you have more info that might help us narrow it down for you!

    Unles the noise is very loud I tend to think that the noise may be normal. Without hearing it I can't be positive. If the unit is only 2 weeks old, I would suggest calling the repair center where you purchased it or if they don't have a service dept. , I would just contact the manufacturer to be refered to the nearest Authorized service center. Trying differenet cycles should only change wash time, water temp etc. Let me know if you find a problem with it if you decide to call a tech. Thank You!

it's probably your pump starting. has it always made this noise or just started. or does the noise start then go away? if it stays on all the time i'd say your pump is getting ready to go out this is something you could change yourself save $$$ just get the make and model # of the side of door. then call an appliance store see if they can get one first before you take it apart if it's an old model might be best to get a new one (dishwasher) if and you get a pump the water shut off should be under you sink just the hot then pop the cover off bottom of dishwasher (TURN OFF POWER FIRST TO DISHWASHER!!!) it would easier if you pulled the unit out then tilt it back and you'll see the pump the rest is pretty easy. good luck

LG Dishwasher LDF7811 Making Growling Noise

-Switch to a brand name detergent powder - like Electrosol or Cascade and do not fill the dispenser cup full. You will notice the difference immediately.
-Remove the filter assembly one more time and inspect underneath with a flashlight. Look closely for debris and also inspect the impeller to look for damage and that it is spinning freely.
Reassemble and listen for the growling sound. It should not happen. If it continues, you may have a a failing wash motor / motor bearing.
Please report back what you find. OK?

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

Well done by resolving this problem. The other way to avoid the siphoning problem through the drain hose is adding an air gap valve/connector (available at any hardware store). You can use it even if you don't have a garbage disposal in your kitchen sink. That will assure that you have the proper height of the drain hose.
Hope this helps!
