washer overfilling and causing door to open and flood house. I checked for holes in the pressure tube and I had that pressure switch on me but it yielded the same results. I did not have a tech sheet when I was out there but It looks like I need a new pcb board that the switch just signals the board and the board does the switching. Or am I missing something.

I I also noticed that when you turned the unit off and back on the door would unlock regardless weather the tub is full or not. I thought this was because the pcb thinks the tub is empty.

Have you checked the cold water valve set to make sure it isn't filling with water while the unit is not operating? They've been known at times to stick open and continue to fill with water at times.

check air dome for debris, i had one a few weeks ago that a piece of a plastic wrapper was in the white tube, you could blow thru the hose not problem but when the unit filled with water the plastic floated up and blocked the hose.

Thanks I'll check for plastic trash that makes since. It seemed to work on drain and spin as far as filling goes it just did not stop draining.

Ah okay I misunderstood the symptom then, my apologies. Yeah check for a clogged pressure hose. Could be soap buildup in hose as another possibility

<<<washer overfilling and causing door to open and flood house.>>>

 

**********

 

Does the overfilling occur when the washer is NOT being used?

 

**********

 

<<< I also noticed that when you turned the unit off and back on the door would unlock regardless weather the tub is full or not.>>>

 

**********

 

This is normal. The water level never reaches the door opening (except during the Tub Clean Cycle---door remains locked)

 

However---the door WILL remain locked in instances of *overfilling*.

 

The door will also remain *locked*---if the tub is still turning/rotating (Hall Effect Sensor monitors this)

<<<as far as filling goes it just did not stop draining.>>>

You'll need to explain that one better for me

 

What's the Serial Number?


Edited by john63, 19 October 2014 - 06:36 PM.

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"

No it is not over filling unless you start a load the valve is shutting off properly. You can press cancel or power to stop the filling when it starts to over fill. The door lock works but fails when the tub is about 80 - 90% full of water. It just can't hold the weight.

I press normal wash with a load of towels inside the tub and it begins filling. The tub will fill until it has completely filled every bit of air space in the tub if you hold the door or the door will then pop open and flood the house but the lock is working up untill the water is 3/4 the way up the door. I can press pause or power to stop the fill then I change the selection to spin and drain because I can't find a cancel button it will eventually start to drain but it never stopped. the tub never goes into spin. It just keeps draining. No holes or blockage in pressure tube or the air dome. Switch is switching contacts with pressure changes.

Incomplete Serial Number

<<< it will eventually start to drain but it never stopped. the tub never goes into spin. It just keeps draining.>>>

 

**********

 

From this statement---it can be assumed that the washer does the following...

 

1) Overfills with water

 

2) Washer sometimes fails to enter EMERGENCY DRAIN MODE---door pops open and floods laundry room

 

3) Other times---the washer DOES enter EMERGENCY DRAIN MODE---and drains continuously

 

NOTE:

 

The Serial Number helps identify the unique software features of this model washer

It does not have cancel but it does have pause and power they both will stop the filling. I will have to recheck the serial number when I'm out there next.
It never enters emergency drain mode it only drains when I select drain and spin. And wait till the timer gets to about 9 minutes.
