New LG LFXS30766S refrig. Water disp.not putting out full stream of water despite doing what the manual said to do. Old Maytag refrig. I had put full stream of water with no problem.Any suggestions?

That model number appears to be a refrigerator and not a cell phone.

read your operators manual
the machine is not designed to put all of your clothes in at once to start with and second the water level for a full load is high not normal
the normal refers to a normal mix of clothes and not water level
special wash is for delicates ( undies , silk etc ) or heavy wash is for heavy soiled clothes --coveralls , jeans , heavy jackets

Hello Kay Campbell,

You need to pull (ROLL) out the refrigerator from the wall...

Typically will expose but the POWER & WATER
supplies. You will need to find the control valve
BEFORE disconnecting the "water" hose/pipe...
(A small wrench will be required
(preferably a tubing wrench)).

You will need to disconnect BOTH...

Refrigerator ROLLERS on "old vinyl" flooring...
is not advised... On new VINYL... can cause ripping
and serious damage...

You should get out your OWNERS manual & follow
the instructions (precautions to PROTECT your floors.

Typically a bit of cardboard is sufficient to protect
new vinyl flooring ... but it is BEST TO FOLLOW
MANUFACTURES INSTRUCTIONS...

Refrigerator "ROLLERS" are always a PROBLEM...

Put the old one back in and if water works, then the new filter is blocked. Buy another filter.......

The new energy efficient LG dishwashers take 2 hours from start to finish depending on water temp. Run your hot water at the sink prior to starting the unit.

I see all the time inproper loading of the dishwasher blocking the sray arms.

Put 1 teaspoon of detergent in the soap dish.
Run the unit without anything in it.
If the soap washes out the unit is ok.

Also here some improtant info. that often gets overlooked when a new dishwasher is installed.

Replace the water supply valve under the sink and water supply line to dishwasher.
Over time minerals deposit in the valve and restrict the water flow to the dishwasher.
This is especially inportant on todays water saving units.
Many people replace an old dishwasher and hate the new unit due to a white film left on dishes.

Although you may have paid for a professional installation a new shut off valve is almost never replaced even though the waterline may have been at an additional cost to you..

Pull disp out. Check to see if its clean. Put into sink and run a sead stream of water into bleach cup till overflows and syhpon tube begins to drain water. Turn of spicket while holding disp steady and level. If the water drains cold water valve is faulty or screen is restriced reducing water preasure. Poor water preasure will prevent proper syhponing. If disp doesn't syphon or drain water out while in sink its either faulty or dirty.

the filter for this unit is located in teh upper right hand corner of the refrig ceiling. there is a thumb latch on the cover release teh cover and you will expose the filter. turn the filter 1/4 turn counter clockwise to release. then reinstall new filter. be sure to run approx. 1/2 gallon of water thru the dispenser after replacing filter to purge air from the lines. 
p.s the icemaker and water disp will not work without the filter in place. Have a Great Day! peyton

a possibility is that the water tank has frozen up in the refrig side. what i do is remove the middle crisper drawer and put a hair dryer blowing on the water tank in the back. do this for about 5 mins then start trying to get water out of the disp and it will clear it out. peyton

1) Electric Water valve check up.
2) Water/Ice dispenser control check up
3) frozen plastic pipe inside door or/and chilled water container frozen
4) old water filter (clogged)

disconect water line and make sure you have water pressure.
