Not heat

Have you checked the Service Manual?

Edge Biomedical may be able to help you.

is medwrench giving up on it's "medwrench is  aresource of direct questions...." everytime someone asks for a manual?

Jj erick, when you say the liquid comes out from the chamber. Do you mean the water is leaking out from the door? or water is entering the chamber? Are you sure your door switch is being engaged?

I would pull the cover off and check the multipurpose switch.  Make sure the micro switches are engaging. If they are look at your heating element. Ohm it out and check for voltage.
