We ordered the bottom sprayer but now it makes a noise and doesn't seem to rotate around as it should does it require something else to fit correctly?
There is nothing that is used to make it fit correctly. The spray arm would just push down into the pump assembly and lock in place. You will want to make sure that it is fully seated.
How do I know if the spray arm is bad? It wobbles around a lot when I touch it.
Answer Hello Vinylgirl60. The spray arm 154568001 is suppose to be loose, but shouldn't come off during the cycle. You can look and see if the spray arm is clogged or cracked. If so, you will need to replace the spray arm. Hope this helps.
