Test the Heating Elements — Test Heating Element and Thermistor
Part of project
Dishwasher Repair · Step 7 of 10
In this video
The final major electrical components to test are the heating elements. Switch your multimeter to resistance mode (ohms, Ω). Carefully place the probes across the terminals of each individual heating element. A healthy heating element should present a specific resistance reading. The video shows readings of approximately 11.8 ohms and 12 ohms for two different elements, indicating they are in good condition. Significant deviation (e.g., very high or infinite resistance) suggests a faulty element.
FAQs
What are the most critical safety precautions I must take before attempting any dishwasher repair?
Always disconnect power to the dishwasher at the circuit breaker and turn off the water supply before starting any work. Use a non-contact voltage tester like the FLUKE 1AC-A1-II to confirm that no power is present at the appliance, preventing electric shock. For tasks involving electrical components, double-check that your hands are dry and you are using insulated tools.
Do I need specialized electrical tools like a multimeter or voltage tester for common dishwasher repairs?
Yes, a non-contact voltage tester (e.g., FLUKE 1AC-A1-II) is crucial for safely verifying power is off before touching internal components. A digital multimeter (like the Klein Tools MM325) is highly recommended for accurately diagnosing electrical components such as heating elements or thermistors, helping you pinpoint issues with precision.
How difficult is it for a beginner to diagnose and repair common dishwasher problems, and what's the estimated time commitment?
This project is rated as beginner difficulty, as many common issues involve simple checks or component replacements. Expect to spend around 4 hours for diagnosis and repair, though complex issues or sourcing specific parts may extend this. Patience and careful observation are key for successful troubleshooting.
My dishwasher isn't draining properly; what are the most common culprits a beginner should check first?
First, check the drain hose for any kinks or blockages, especially where it connects to the sink's air gap or garbage disposal. Next, inspect the dishwasher's filter and drain pump for food debris, glass, or foreign objects. A clogged filter or an obstructed pump impeller can severely impede drainage, often requiring just a thorough cleaning.
