A spill-resistant appliance may be constructed to prevent spilled liquids from entering a control housing and contacting electronics with the use of a first sealant preferably formed out of santoprene and a second sealant preferably formed out of a very high bond, double-sided foam tape. The first sealant and the second sealant may be used in various areas of the control housing that contains electronics for operating the appliance. The first and second sealants may also be used to help attach the control housing to other components of the appliance.
