How can I test if my heating element is bad?

You can test a heating element for continuity using a multimeter. After disconnecting power, remove the lower access panel and disconnect the element's terminals. Set your multimeter to the ohms setting and touch the probes to each terminal. A reading of infinity or no continuity typically indicates a failed element.

Is it safe to run my dishwasher with a broken heating element?

While it might still wash, running a dishwasher with a faulty heating element is not recommended. It can lead to inefficient cleaning, dishes not drying properly, and potentially further damage to other components if the element is shorted or causing electrical issues. It's best to replace it promptly.

What causes a dishwasher heating element to fail?

Common causes include regular wear and tear over time, mineral buildup from hard water which can corrode the element, or electrical issues like surges or shorts. Sometimes, foreign objects or harsh detergents can also contribute to premature failure by damaging the element's surface.
