Model: DW 70.1
Art No: 1075122120
Complaint - Drain pump always on.
Last week I went out to this DW and found the microswitch in the basepan float assembly melted out. I replaced the switch and melted wires and the customer was able to use the DW 1 time for a complete cycle. The 2nd time she ran it, the drain motor clicked on again and continued to run until she shut off the power.
I went back today and found the microswitch burnt out again. (See picture.) There is some soap residue in the base but it was dry.
What is causing this switch to burn out and short to closed?
Would love any input at all. Thanks!
