There are number reasons that your Hot Water System (HWS) is not functioning. It is not possible to provide any helpful diagnostics without more information. We recommend that in the first instance you consult the operating the instructions for the HWS and check the troubleshooting checklist. Failing this your selling dealer is your "home base" and their service team are standing by to assist. Kind regards, Sunliner RV.
