Stop the water and power first

A breaker that trips is doing its job. Leave it off, close the supply valve under the sink if there is water in the tub, and do not bypass the GFCI or swap to a larger breaker. If you see scorching, smell burning, or feel a tingle touching the door, keep everyone away from the machine until it is checked.

What it
usually means.

A breaker trips because the circuit sees more current than it should, or because current is leaking to ground. On a dishwasher, the heating element and the motors draw the most, and water is never far from either. When the trip happens is the most useful clue: at the moment the machine starts, when it begins to heat, or only when the disposal on the same circuit runs.

Answer these first

01

Does it trip the instant the cycle starts, or several minutes in when the water heats?

02

Is the dishwasher on a GFCI outlet or a GFCI breaker, or a standard breaker?

03

Does the garbage disposal or another appliance share the same circuit?

04

Was there a leak or water under the machine shortly before this started?

05

Does it trip on every cycle, or only now and then?

Dishwasher tripping breaker: 5 checks, and none of them costs anything.

01

Leave the breaker off after the second trip; resetting it again and again can damage wiring.

02

Check for water under the dishwasher by removing the kick plate once power is off.

03

Find out whether the disposal or another appliance shares the circuit, and whether both were running.

Also worth checking

  • Note the point in the cycle where it trips; heating and startup point to different parts.
  • Check whether the outlet under the sink is a GFCI with its own test and reset buttons.

5 things dishwasher tripping the breaker turns out to be, from shared or undersized circuit to wash or drain motor drawing too much current.

The cost guide
  1. 01 no repair

    Shared or undersized circuit

    A dishwasher and disposal on one 15-amp circuit can trip it when both run. That is a wiring layout question, not a dishwasher repair.

  2. 02 low to moderate

    Heating element shorted to ground

    An element with a cracked sheath leaks current to the tub, which trips a GFCI as soon as heating begins. It is the most common cause.

  3. 03 low to moderate

    Water reaching wiring under the tub

    A leak that drips onto the terminal block or a motor connector creates a path to ground. Fixing the leak and drying the wiring may be all it needs.

  4. 04 low

    Damaged power cord or junction box connection

    A pinched cord or a loose wire nut in the junction box shorts intermittently, which is why the trip can seem random.

  5. 05 moderate

    Wash or drain motor drawing too much current

    A seized or failing motor pulls far more than its rating at startup, which trips the breaker when the circulation or drain step begins.

Questions about
dishwasher tripping the breaker.

Can I just move the dishwasher to a bigger breaker?
No. The breaker size is matched to the wire in the wall, and a larger breaker lets that wire overheat before anything trips. If the dishwasher and disposal genuinely overload a shared circuit, that is a job for an electrician, not a bigger breaker.
It only trips the GFCI, never the main breaker. What does that mean?
A GFCI trips on a small leak of current to ground, not on overload. On a dishwasher that usually means moisture on wiring or an element whose sheath has cracked. It is a useful clue and worth telling the technician.
Is it safe to run the dishwasher with the breaker reset until the visit?
It is safer not to. If it tripped on its own, the condition is still there. Hand-wash for a few days rather than letting a shorted part heat up each cycle.
Could the problem be the outlet rather than the dishwasher?
Sometimes. GFCI outlets wear out and get more sensitive with age, and a damp sink cabinet makes it worse. Plugging a lamp into the same outlet does not prove much; a technician can measure the dishwasher's leakage directly.
