Why Does My Dishwasher Keep Tripping the Breaker?
You load the dirty dishes, close the door, press start—and a few minutes later, the kitchen goes dark. The breaker has tripped again.
This is one of the most inconvenient dishwasher problems. But the good news is, it’s often caused by a few common issues that you can troubleshoot without calling a repair person right away. Let’s walk through why it happens and what you can safely check.
TL;DR
- A tripping breaker can mean a circuit overload, a faulty heating element, or a ground fault .
- Try a simple reset first—turn the breaker fully off, then back on .
- Check if other appliances are on the same circuit—dishwashers often need a dedicated circuit to avoid overloading .
- A damaged heating element is a common cause—it can short out and trip the breaker .
- If the problem persists, stop using the dishwasher and call a qualified technician .
The Most Common Causes and What to Do
1. An Overloaded Circuit
Your dishwasher might be sharing a circuit with other kitchen appliances like the garbage disposal, microwave, or a mini-fridge. When they run simultaneously, the combined draw can exceed the breaker’s safe capacity .
What to do: Check your breaker box and see if other appliances are on the same circuit. Try unplugging the other devices and run only the dishwasher. If the tripping stops, you have found the problem. A dishwasher should ideally be on its own dedicated circuit .
2. A Faulty Heating Element
The heating element is a common culprit when a dishwasher trips breakers. If the element is cracked, shorted, or broken, it can cause a ground fault or a short circuit . Look for signs like burning smells, blistering on the element, or visible breaks . Sparks or arcing from the element are a serious sign—if you see that, cut the power immediately .
What to do: Inspect the element for visible damage. If it looks burned, blistered, or broken, it likely needs replacing. Testing the element for continuity with a multimeter is the next step, but requires some DIY know-how and safely accessing the wiring . If you are unsure, call a pro.
3. A Ground Fault
A tripping breaker can also indicate a “leakage to the ground”—an electrical fault where current is finding an unintended path . This is a safety issue. Modern Arc Fault Circuit Interrupter (AFCI) breakers, which are common in new homes, can be sensitive and trip due to certain motor loads, sometimes called “nuisance tripping” .
What to do: Try the simple reset process first. If your home has AFCI breakers, and the dishwasher worked fine before but trips frequently now, the problem could be a faulty AFCI breaker, not the dishwasher itself. This is a common enough issue that some builders have swapped out AFCI breakers for standard ones . However, AFCI breakers are there for fire protection, so swapping one should only be done by a qualified electrician.
Step-by-Step Troubleshooting Guide
Follow these steps in order. Stop and call a professional if you see any signs of burning, charring, or sparks.
- Perform a power reset: Turn the dishwasher breaker all the way to “off.” Leave it off for a full minute, then turn it firmly back to “on” .
- Check for overload: Unplug any other appliances that share the dishwasher’s circuit. Run only the dishwasher .
- Check the GFCI outlet (if applicable): Some dishwashers plug into an outlet under the sink. If it has a GFCI outlet, press the reset button .
- Inspect the heating element: Look for cracks, blistering, burns, or broken sections on the element at the bottom of the tub .
- Call a professional: If the breaker trips immediately upon reset or after following the steps above, do not attempt to fix the appliance yourself. Electrolux and Bosch both recommend contacting an authorized service center .
Comparison Table: Common Causes and Fixes
| Likely Cause | What It Looks Like | What to Do |
|---|---|---|
| Circuit Overload | Breaker trips when running dishwasher with other appliances | Unplug other devices; give the dishwasher its own circuit |
| Faulty Heating Element | Breaker trips during the cycle; burning smell, visible cracks/blisters on the element | Replace the element or call a technician |
| Ground Fault / Nuisance Trip | Breaker trips sporadically; home has modern AFCI breakers | Try a power reset; consult an electrician about the breaker type |
| Internal Electrical Fault | Breaker trips immediately when you turn the dishwasher on | Unplug and call an authorized service technician |
FAQ
Why does my dishwasher trip the breaker immediately after I turn it on?
This is often a sign of a severe internal electrical fault, like a short circuit or a damaged component . Do not keep trying to run it. Unplug the dishwasher and call a professional.
Is it safe to keep resetting the breaker for my dishwasher?
No. If your dishwasher trips the breaker more than once or twice, there is a problem. Repeatedly resetting a breaker to run a faulty appliance can cause further damage, create a fire risk, or damage the breaker itself.
How do I reset the circuit breaker for my dishwasher?
Find your breaker box. The dishwasher breaker should be clearly marked. To reset it, push the switch all the way to the “off” position, then firmly back to “on.” It should click into place .
What does a burning smell from my dishwasher mean?
A burning smell often points to a shorted heating element. A damaged element can overheat and cause a burning smell as it begins to fail . Stop using the dishwasher immediately and inspect the element.
