No I don't think so.\r\nI have an Americh 6 jet

If you have hard water you will get lots of crud build up in the pipes.

Try soaking the jets in the cheapest vinagar you can find. The weak acid in the vinagar is great for getting crud off plumbing. Let it soak for at least 15 min then give it a try.

If this frees it up a little try the cheapest dishwasher powder you can get. The cheap stuff is a little abrasive and works great at cleaning jets.
