Dishwashers operate on high-current circuits where residual moisture can increase the risk of a fatal electric shock.

Testing for Ground Faults and Insulation Leaks<\/h2>\n    <p>Even if an element has continuity, it may suffer from a &#8220;leak to ground.&#8221; This occurs when the internal <strong>Magnesium Oxide (MgO)<\/strong> insulation degrades, allowing current to flow from the NiCr wire to the outer <strong>Incoloy 800<\/strong> sheath. This often trips GFCI breakers or creates a safety hazard in the wash water.<\/p>\n    \n    <p>To perform this test, keep the multimeter in the Ohms setting. Place one probe on a terminal and the other on the metal sheath of the element or the dishwasher&#8217;s grounded frame.
