Ah, you are discovering the joy of the Mark 7 parts system. You are pretty much stuck with them. On some items, like that presoak pump and coupling, you can change it to a regular pump, but on most items you will pay. Their policy in Florida makes it laughable for their techs. When the part leaves Mark 7, they start the warranty on that part. It is common to have a part sit on a shelf or van for several months before being used, but by then half its warranty may be gone. Be sure to ask about that. Because of this the techs I see here don't carry the electricle parts. They troubleshoot and NDA the parts in, so most service calls require two trips. That may not be their policy everywhere, but it is here. You might try Landons in Pennsylvania, he carries parts for their domestic machines and may have some of these.
