I have a 2008 LG LDS4821ST and am not really happy with it.  

 

A few months ago it started making an intermittent noise.  it was so loud that it could be heard through the whole house.  I replaced the sump assembly.  the noise stopped, but now it does not clean the dishes.  there is no water in the dishwasher, but it is full of dirty dishes.

 

When i installed the new sump, i checked to make sure all of the connections were correct.  the wires are connected to the same terminals that they were removed from.  And the water supply is turned on.

 

it seems like the water will fill at the  beginning of the cycle, but it will immediately drain out before the wash cycle.  when i add a few gallons of water mid-cycle. it seems to wash normally.

 

WTF?

 

How can i fix this?

A few questions...

 

1) What is the Serial Number?

 

2) What is the Part Number of the replacement Sump Assembly?

 

3) What is the *build date* of the replacement Sump Assembly (located at the bottom)?


To eliminate:

Musty odor

L-O-N-G cycle times

Dingy/yellowing whites

Suds error message

Slow spin speeds

Intermittent water leaks (from rear of washer)

And other annoying symptoms which vary brand-to brand.

Read below:

The *correct* amount of HE (High Efficiency) detergent that should be used in any front load or agitatorless top load washer with tub sizes 3.0 cu ft and larger is as follows:

HE: (2) Tablespoons Per Wash Load

HE 2X: (1) Tablespoon

HE 3X: (1) Teaspoon

Perform a TUB CLEAN CYCLE every (4) months.

Use: "Tide Washing Machine Cleaner"

<<<808kwxd00906>>>

<<< seems like the water will fill at the beginning of the cycle, but it will immediately drain out before the wash cycle.>>>

**********

I'd replace the GUIDE ASSEMBLY (4975DD1001A)---verify that the date of build shows February 2011 or newer.

Part number: AP4442244

Part number: AP4442244



The revised Guide Assy corrects several problems (water leaks/poor wash/fill-then-drain/etc)

Additional Info...

For the LG Dishwasher LDS4821 with Serial Numbers in the range of---804KWxxx to 906KWxxx---a Service Bulletin was issued to address infrequent "HE" errors.

The original Main Board is (EBR33469402)

The revised/improved Main Board is (EBR33469404)

Part number: AP4514740

Part number: AP4514740


The new M/B has a software change to be less "sensitive" to slightly higher-than-Target-Temperature (when the heater heats the water)

I don't know but could it be a siphon issue.  Maybe the drain hose is too low and not braking the siphon.  Just thought I'd throw that in as something to check.

If the dishwasher "loses" water due to siphoning (low drain hose)---this will trigger an "E1" error.

 

Any error messages displayed, hunt194?
