Need Appliance Repair Help? Ask a Technician for Answers ASAP
Hi. I'm Smitty. I am a professional appliance repair consultant here to help you diagnose, and repair, your appliance.
Put it back together but leave access to the pump. Start the unit and let it fill some. Set it to a drain cycle and measure the voltage to the pump. You should have 110vac. If you do not then replace the main conrtrol board. If you have 110vac at the pump see if it actually pumps the water out before you get the error code. If it does then the water level pressur switch is the problem. Pull the hose off of it and blow through it. It should be clear. If not clear it, or replace it. If the hose is clear then replace the presure switch.
If you would like any additional information or have more questions please don't hesitate to ask!

Ok below is the flow chart for the OE error code. Check these items and if all ok please let me know.
This is the formula for the water frequency readings.
Press the CUSTOM and PRE-WASH buttons simultaneously. The digits indicate the water level frequency.For example, if the display indicate 41, the water level frequency is 20+(41X0.1) = 24.1 kHz.
Thanks Smitty. I'm not going to be able to get back on this till tomorrow. It's 11 PM here. I've never used this site before so I have one more question. I feel like you've answered my original question very well. I mentioned that if it got into electronics on the board, I'd probably be in over my head. As a contractor the last thing I want to do is take advantage of your time, so how do I handle this? I want to be sure you get paid for this, but can I come back to you after I've tried some of these steps when I put the washer back together tomorrow or would that be going beyond my original question? I trust your answer on this, your reputation speaks for itself.
Tim, go ahead and do what you feel comfortable doing and then if you want I will walk you through the rest. Rating me now will not close the question. You can ask all the followup questions you like untill we get this resolved.
Im thinking that the pump is not getting voltage from the main control board. If that is the case then testing the pump for proper ohms reading, and then for voltage at the control board is the only way to know.
I agree. I don't see what else it could be but a voltage problem coming from the board. I won't know until tomorrow but I'm assuming I can put everything back together but leave the control panel haning where I can access the board. Thanks again. Job well done!
Good point, I'll do that. Thanks again.
You are welcome Tim. Let me know if you need anything else. Ill be on most of the day tomorrow.
Have a good evening. =)
Hey Smitty, are you online?
I measured the ohms on the motor leads. I'm getting 27.7. The manual page you posted said it should be 10 - 20 ohms. I haven't put everything back together yet. The manual says to replace the pump assembly. Does it sound like that will fix the problem or will I not know until I button it up, put the existing assembly in and check the voltage?
If the ohms reading is high then the motor is probably on the way out. You can button it up and test at the control board, but if the board shows good you will have to tear it apart again to replace pump motor.
This time it is your decission, Tim.
I want to give you an excellent rating but I don't see where to do that.
Nothing to do with your service, but a general complaint about the industry. I'm flustered. I've been pricing that little drain pump and I can't believe that little nothing motor encased in plastic is $60.00. What a racket these appliance parts are. I know they have to make a living, but I compare everything to what I sell and there's no comparison. I'll sell a 125 amp panel for about that price and it will last 30 years.
Sorry, just had to get that out of my system. If you would tell me how to do the rating I'll get right on it.
Thanks again for the help.
I was going to try one more thing and I realized the page you posted from the manual wasn't for my model. I want to try to check the water level frequency using the CUSTOM button and the PRE-WASH button, but my model doesn't have a custom button. Is there any other button I can use to try this?

Tim I am so sorry but this is the first I have seen of your replies!
You have already rated me so dont worry about that.
This is a definate glitch in the system and I will be informing our staff about it.
I have to step out for about an hour or so. I will give your question my complete attention at that time.
Sorry for the inconvienience.
WOW! this is the first time that the drain hose itself turned out to be the problem. If it gets clogged then you bet it affects the drain system.
Of course it is ironic that every drain problem solution starts out with "check that the drain hose is clear and unobstructed".
Sometimes you just gotta go back to the basics and get schooled again.
Glad you got it going, Tim.
