KitchenAid Dishwasher E3 Error — Power Reset Fix

What it means

KitchenAid dishwasher E3 is one of the codes KitchenAid's support site treats as a generic control-side fault — they don't publish a specific component as the cause.
The only fix KitchenAid lists is a 30-second power disconnect to reset the dishwasher's electronic control.
If the code returns immediately after the reset, schedule service.

Affected Models

KitchenAid KDPM, KDTM, KDTE, KDFE built-in dishwashers
KitchenAid KDPE, KDPE804K, KDPE234G series
KitchenAid PrintShield, Architect II, and panel-ready models
KitchenAid KUDS legacy series (older models)
Same codes appear on Whirlpool, Maytag, and JennAir dishwashers (shared platform)

Common Causes

Intermittent control board fault
Brief power-supply glitch confusing the control
Sensor reading the control rejected as out-of-range
Stuck routine after a paused cycle or interrupted power
Control board failure (if the reset doesn't clear it)

How to Fix It

Disconnect power for 30 seconds.

Plug-in models: pull the plug at the outlet under the sink for a full 30 seconds, then plug back in.
Hardwired models: switch the dedicated breaker off at the electrical panel for 30 seconds, then back on.
This is the only step KitchenAid publishes for E3.
Confirm the code is gone.

After power restores, the panel should light normally with no E3 displayed.
Start a short cycle (Rinse Only or Quick) to verify the fault doesn't return immediately.
Schedule service if E3 returns.

If E3 reappears straight after the reset or on the very next cycle, the control board may be failing.
This is a service call — replacement boards are model-specific and the diagnostic needs the technician's reader.

When to Call a Professional

If a 30-second power reset doesn't clear E3 — or if it clears and the code returns on the next cycle — schedule service.
The fault is on the control side and isn't owner-serviceable beyond the power cycle.

Frequently Asked Questions

Why won't KitchenAid say what E3 actually means?

KitchenAid's consumer-facing support pages publish a fix step but not the technical cause for several of their dishwasher codes (E3, E6, E7, F2E2, F3E2 among them).
Service technicians get a separate tech sheet inside the door panel with the full meaning — but it's not in the customer manual.
For E3 specifically, a power reset clears the majority of cases, which is why it's the only published step.
