Samsung WF328aaw-02 - Keep Losing Main PCB - OE Error

6 posts in this topic

I had an OE error some time ago on my Samsung WF328aaw-02 front load washing machine. It took a while to get the correct main PCB for this model (02) but I finally got it. After 2 loads, it went down again for the OE error. This time I did not screw around. I replaced every electrical part in the machine except for the motor and the wiring harness. i.e. New level sensor, new silver care pcb, new emi filter and new main pcb. It ran fine for about 3 weeks and then the OE error came back.

It is not the pump, I can dump water in the drum and it pumps it out right away.

It is not suds, I blow through the tube, disconnect the tube etc. and no change.

Once I get the OE error, I know for sure that something has happened to the main PCB because it does not go away until I put a new one in it. As soon as I install a new main PCB the error is gone (at least for a few loads).

The only common denominator that I have is that every time the OE error starts (and I lose the main PCB) it is after a pretty heavy duty load is washed. Usually a quilt or a bath mat or something has been washed. And everytime I am surprised at how heavy the load is when I pull it out (its soaking wet of course).

Do you think there is any chance that when a heavy load is washed that there is excessive current being drawn by the motor (2 years old) and this is somehow either over heating the main PCB or causing some sort of current drain issue that is taking out the level sensor circuit on this machine? I did ohm the motor and it ohms out fine (all 3 legs) But, the first controller Sears sent was the wrong one (for rev .01) and when I ran a load it errored out and when I checked the motor it was smoking hot so I know it had to do some damage to the coils or at least shorten the lifetime.

My next plan of attack is to replace the main pcb and the motor at the same time. This washing machine is costing a fortune to troubleshoot! Not to mention I already had to buy a second washing machine (cheaper top load model) which I keep having to move in and out of the garage to use temporarily when the Samsung fails.

An "OE" error indicates that the MAIN BOARD received data-feedback from the WATER LEVEL SENSOR---that an *overflow condition* occurred (too much water in tub).

When this error is detected---the DRAIN MOTOR will automatically begin pumping/draining the water from the washer until the water level is below the *overflow" level.

Usually the fault will be caused by one of two components:

1) Faulty WATER LEVEL SENSOR.

2) Failing/faulty WATER INLET VALVE---keeps filling water intermittently when valve should be "off".

There are two sets of WATER VALVES---one for Hot Water and one for Cold Water.

<<<I checked the motor it was smoking hot>>>

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

1) Smoke coming from STATOR (motor): Not Normal

2) STATOR & ROTOR (entire motor assy) *very* hot after a heavy load/cycle: Normal

To clear a stored error message from the MAIN BOARD---unplug the washer for 1 minute.

Unplugging the unit for 1 minute does not clear the error. I have left it unplugged for days and it does not clear. The reason the motor was smoking hot was because the first main pcb Sears sold me was for a different revision of the unit that I had. Samsung changed the motor to a different one mid way through the production of this model. So the main pcb that they sent was not compatible with the motor in my unit.

I understand what the OE error is. In my case, it is not actually over full. The unit is completely empty. And the water valves are functioning normally. Thanks for your help, what I am trying to determine is what is causing my main pcb to keep failing (always in the same manor).

I would call the Samsung Parts Dept---for the *correct* MAIN BOARD part number.

There are FOUR different versions of the Samsung WF328 model washer.

Your model (if in the United States) is:

WF328AAW/XAA / 02

You'll need to provide the SERIAL NUMBER as well.

Incorrect part orders are *very* common---even for appliance techs.
