Guys, (not to offend any Ladies here)
I've been working on a newer GE 27" Stack, from memory it was manufactured in 2011. This Model Does Not Have A Mechanical Timer, it has a control board.
The owner complains that it's taking too long to wash. Pulling the Tech Sheet (which I wish I had a copy with me) the unit has Diagnostics codes. (by a series of LED on the front panel). Checking the Errors it had two, "Over Fill" and "Pump Time Out". With the two errors pulled the Level Sensor. Opening it up it appeared to be working properly. This one reads Resistance from a carbon track on a small circuit board. Putting it back in and Clearing the Error Codes, it stated up normally. Filled the drum to the 1/2 way point with water and stops. Going into the wash cycle, it senses the load by pulsing the agitator. Everything looked OK but it throws the same two errors.
This thing is so new, I've been unable to find anything (problem wise) with it. Running a search on New GE 27 Stack I get back Model Number GTUP270EMWW. This unit looks exactly like the one I'm working on. I have no idea where it was purchased.
Any ideas or Help would be appreciated.
