The dial or knob on my GE Profile washer needs to be advanced at least twice midway through the wash or rinse cycle. I don't know if this is because of a faulty timer or defective knob. I bought a replacement knob for $10 but it came with no installation instructions and the original knob doesn't just pop off. Does anyone know how to remove the original knob and install the replacement? The model number is WPSQ416OT2WW and the part number is WH1X2754.
