Shortly after the warranty expired, our Siemens WFXD5201UC Front Load Washer began to stop mid-cycle. At first it was "occationally", now it is "usually". But, it is still random, and happens at odd times in the cycle. It most often stops with about 21-35 min remaining on the 59 min Regular cycle but will go as low as 1 min remaining. Occationally it will complete the cycle and beep but the clothes will still be soaking wet. The times I have caught it in the act, it is after the pump runs to drain the water, the drum doesn't turn to spin out the load.

The problem is with the main control module ( push button spin dial and display) Im in the process of having my second one replaced. The problem is with the start/stop button that will not engage unless you hold it down for more than a minute...or durring a cycle the button will engage an pause your wash cycle. My opinion its a design flaw with the board, maybe moisture is reaching the switch causing corrosion or something like that. But its happened twice good thing i have extended warranty the part alone ranges from 365.00-479.00 on line part# 00661096
