Kenmore Washer Tripping Circuit Breaker — Troubleshooting Guide

A Kenmore washer that trips the circuit breaker has either a short circuit (conductor touching ground/neutral) or a ground fault (current leaking through water or insulation to the cabinet). This is a safety-critical issue — the breaker is doing its job protecting you from electric shock or fire. Do NOT repeatedly reset the breaker and try again.

When Does It Trip?

The timing tells you which component is likely at fault:

• Immediately when plugged in: Short in the power cord, motor winding shorted to ground, or control board dead short. On 796-series, the noise filter can fail as a dead short.
• When the cycle starts (fill begins): Inlet valve solenoid shorted. On 110-series, the timer contact closing the valve circuit may be arcing to ground.
• When the motor starts (agitate/spin): Motor winding shorted to ground or water has entered the motor housing. On 796-series, a failed stator winding that contacts the rotor.
• When the drain pump starts: Pump motor winding shorted (especially if pump housing has leaked and water reached the motor terminals).
• Randomly during cycle: Intermittent short from a chafed wire contacting the cabinet. On 110-series, the motor wire harness underneath the machine can abrade against sharp cabinet edges over years.

Most Common Causes by Platform

Kenmore 110-Series (Whirlpool)

#1: Motor winding ground fault — water from a leaking center tub seal (or pump hose) drips onto the motor below, degrading winding insulation. Trips during agitate or spin.

#2: Power cord damage — the cord exits at the bottom-rear where it can get pinched against the wall. Internal conductor damage creates a short.

#3: Timer contact arcing — a burned timer contact can arc to the timer's metal frame (grounded), tripping the breaker when that contact cycles.

Kenmore 796-Series (LG)

#1: Noise filter (line filter) dead short — the EMI filter component fails short-circuit rather than open. Trips immediately when plugged in.

#2: Stator winding ground fault — water from a failed tub bearing seal reaches the stator windings, creating a path to ground through the tub shell.

#3: Heater element ground fault (models with internal heater) — the heating element develops a crack in its insulation, and water creates a ground path.

Kenmore 417-Series (Electrolux)

#1: Drain pump motor short — these pumps sit at the lowest point and are prone to water ingress from minor leaks.

#2: Door lock PTC element short — the heating element inside the door lock can fail short.

Diagnostic Approach (Professional Level)

1. Unplug the washer.
2. Megohm test: Use a megohmmeter (insulation tester) between each power conductor and the ground conductor at the plug. Should read >1 megohm. Low reading = insulation breakdown.
3. Isolate components: Disconnect the motor, pump, valve, and heater (if present) one at a time, then plug in after each disconnection. The trip stops when the faulty component is disconnected.
4. Visual inspection: Look for scorched wires, melted connectors, water on electrical components, or chafed insulation.

Safety Warning

This is one of the few washer repairs we recommend professional diagnosis for (all platforms). Ground faults and short circuits involve live-voltage testing that requires proper equipment and training. An incorrectly diagnosed ground fault can lead to electric shock through the washer cabinet.

Parts Cost: Varies widely — $5 (wire repair) to $250 (motor replacement) Professional Repair Cost: $150–$400

FAQ

Q: Can I just keep resetting the breaker?

No. Each time the breaker trips, there is a momentary short-circuit current flow that can cause arcing, heat, and fire risk at the fault location. The underlying cause must be found and fixed.

Q: My Kenmore washer trips a GFCI outlet but not a regular breaker — is that different?

Yes. GFCI trips detect current imbalance (leaking to ground) as small as 5 milliamps. Regular breakers trip at 15-20 amps. A GFCI trip indicates a small ground leak that is not dangerous enough to trip the breaker but is still a fault. Common cause: moisture on a motor or pump connector.
