GE Profile machine model WPRE6100G0WT. Water overflows from outer tub flood hose ONLY when set to SUPER load size (no issue on all other load size settings). What appears to be occurring is that the water is being 'sloshed' into the flood hose entrance when the level is at the highest point. This just started about a week ago. I have read through these forums and I have checked the water valve shutoff. That works fine, no issues. My first thought was to just replace the pressure switch and associated hose. The switch seems to be fine (clicks when I apply light air pressure by blowing on it, etc) but still there is the problem w/ highest water level. I also checked the tub dampening straps but these appear to be in OK condition.

I keep seeing comments about the mode shifter and statements that this could be bad if the basket moves during agitation. Is this truly the case? I think that the basket has moved during agitation ever since I have had this washer. I thought that was normal since the agitator is more of a 'passive' device (moves in a locked mode clockwise but rotates freely counterclockwise). I was almost positive that the basket should be moving somewhat during agitation. It rotates clockwise/counterclockwise. Could it be that the mode shifter has been bad ever since I have had this machine and now suddenly it is 'more bad' and causing the water to splash into the flood hose inlet?

So, I have posted a short video here to show the agitation cycle from right after the fill stops (load sensing) through the first few seconds of agitation. I would really appreciate it if anyone knowledgeable on these machines would look at the video and let me know if this movement on the basket is unusual/incorrect. Again, this seems to be consistent with how it has pretty much always operated. I thought this was what it was supposed to do. If it's wrong, it would be awesome if someone could post a vid link of the proper operation for these models.

Just trying to determine if I should replace pressure switch/hose or if I really do have an issue w/ the mode shifter. Also, any links or feedback on the process to replace mode shifter (if this is what is needed) would be appreciated!

Thanks again and I appreciate the input and feedback. This site is extremely helpful.

Eric, thanks so much for your reply and also for posting the vid link. So, I did more testing on the machine tonight now that I found info re: the motor inverter board self diagnostics. I looked closely at that and found that the LED was in fact blinking 4 flashes indicating Mode Shifter Circuit fail. I disconnected the wiring harness to the mode shifter and checked resistance. It shows open (infinity) so something is definitely not right!

I guess at this point I will replace the mode shifter. The machine is in pretty good shape other than this even though it's about 7 - 8 years old. Hate to toss it when I can repair it for < $150 although I don't really relish the prospect of tearing it down completely! Oh well, what else did I have to do this weekend?

Thanks again and if you have any other input or suggestions on things that I should look at while tearing it down, I would welcome the input.
