LG Water Frequency
« on: May 20, 2010, 12:55:09 PM »
LG WM2277HW Washer. In class we are trying to figure out what LG is talking about in the Service Manual in regaurds to water frequency. They give a value but no explination as to what it means?

In the manual page 19 starts talking about it.

Any of you guys know what they are talking about?

Water is overflowing (water level frequency is over 213).
If "FE" is displayed, the drain pump will operate to
drain the water automatically.

When you press the "SPIN SPEED" button and "SOIL LEVEL" button the water level frequency should be above 246. If the water frequency level fails to reach 246 in 8 minutes you will get an IE error or inlet error. You would need to check the water valve, water pressure, etc.
How does the machine know if the water level is complete? Water level switch right? So obviously the control is timing the amount of time it takes till the water level switch kicks off. If it takes more than 8 minutes we have a problem don't we? Therefore if something is partially blocking the tubing from tub to switch that might throw off the water level switch. It is located on the main control assembly and has the rubber tube connected to it. The control board uses this to determine water frequency level. Just blowing the sediment out of that tubing will cure the IE error IF everything else mentioned is all good. I meself would do that first before replacing any parts.

You may prefer simpler design appliances JW but you're demonstrating an understanding of the "computer" models very well.

You'll earn more profit tackling the LG laundry service calls.

************

The WATER PRESSURE SWITCH ASSEMBLY (6601ER1006E) monitors the amount of water entering the washer tub.
This data is sent to the MAIN BOARD.

************************

A very common cause of the "IE" error is from FLOOD CHECK/FLOOD SAFE hoses.

The anti-flood valves often shut off water during normal fill for the washer.

Remove these hoses and install either the factory original hoses or aftermarket hoses without the anti-flood valves.

We found how it works and how its measured. Took 3 of us and our instructor researching it but we figured it out with the help of a LG regional manager and some training manuals.

Pretty slick the way it works because the washer can adjust its water level almost down to the ounce of water it needs to wash a load, depending on what your washing.

When the washer starts and fills with water, the water level switch gets a pressure reading. Instead of either opening or closing a switch, it moves an iron "plug" inside of a coil. This coil is charged and measures how far the iron plug travels based on a magnetic field and inputs the reading to the main control board in KHZ. The main control board takes this info along with the load weight and figures out how much water the load is going to need. For example, if your washing 5 t-shirts, the washer will know it doesnt need as much water as it would need for say 5 beach towels and adjusts the water to a level that best suits the load thats being washed.
