After doing some research through the tech sheets your issue is the water level control, these fail quite often on these machines,
this is located under the top in the back right corner, there are screws along the back of the top you remove and slide the top back and off.
I am giving you the link to your part below, this site has the best return policy on the net, in some cases
the part may be a little more money then other sites but their return policy is unbeatable, if you order a
part from them and install it in the problem still exists they will let you return the part even after it has
been installed . No questions asked. It is well worth the little bit extra you may pay I'm not "saying that's
the case in all instances much of the time it is actually cheaper than other places,
