I just purchased the sump from appliance parts and was told to google the part number and I would find instructions on how to replace the sump which I was told would fix the leak at the bottom of my dishwasher. I watched an excellent video at: that made it looks pretty doable. However, when it get stop the part to take out the base part of the water assembly, over the deserter, it does't look like my unit which has another arm I am not sure how to take off or loosen. Can anyone help with this?
