LG WM2277HW Water does not shut off

12 posts in this topic

I've just replaced a bad cold water activator and now the water will not shut off when the tub is full.

So far:

Good water pressure.

water contiues to flow when pause or stop is pressed.  Stops when unit is unplugged, and doesn't restart untill a new cycle is started.

Tube to level switch is clear.

Level switch reads 225/81 when soil level/ spin speed is pressed on front panel.

All wires and hoses replaced to proper location / orientation.

 

Thoughts?

Update:

The water DOES shut off Pause or Stop is pushed.  It stops just as the door lock is unlocked.

Further update:

 

Seems the center post of the new cold water activator is the source.  Water shuts off if that connection is pulled.  Bad part out of box?

Further:

 

Just moved the center (#2 connection) to activate the other two connection.  Water flows through the activator.  New part is fine (probably).  #2 connection is staying "hot". 

 

Where do I go from here?

 

Hopefully more troubleshooting!

So final note:  The "main wash" connection on the cold water inlet is not shutting off. 

 

Apologies for all the additional posts.

This post is to replace my previous multi post about this issue.  The center connection on the cold water valve is not turning off.  Everything else works fine (if this connection is left disabled-with the exception of cold water fills during wash).

The service manual shows this wire Wht/blk going into the main board. 

 

Thoughts?  Ideas?  Any help would be great.

 

Thanks,

Steve

Have you checked to see if the center valve is always getting 120vac?  If it's not getting 120vac and it's letting water in all the time, it's a bad valve:  http://www.repairclinic.com/PartDetail/Water-Inlet-Valve/5221ER1003A/1268130?modelNumber=WM2277HW

Thanks for the reply.  The issue is the main wash connection is ALWAYS getting 120 v, even during the spin only cycle.  IF that connection is plugged in, cold water contstantly folws regardless of cycle.   It seems to be a new problem since the cold water valve was replaced.

Old valve may have zapped the main pcb.  Have you run the test mode?

I have during the troubleshooting of this.  Is there somethig specific I should look for?  The cold water main just ran all through the test mode, regardless of what other feature was being activated.

Look, the valve is controlled by the voltage from the main PCB. If the main PCB continues to put out voltage to the valve when it should not be, then is the main PCB is bad. This is not rocket science. If a thing is doing what it ain't awwta be doing, then it's a bad thang, and the fat lady done saying on that one.
