The E3 error code on a dishwasher indicates a specific malfunction that stops operation to prevent damage, but its exact meaning depends heavily on the brand since manufacturers use proprietary diagnostic systems.
Why E3 Appears Across Brands
Dishwashers flash E3 when sensors detect problems like heating failures, water supply issues, or leaks that could compromise cleaning or cause floods. Heating element faults dominate in many models (water not reaching 120–160°F), while others point to low fill or excess water triggering safety shutoffs. Always check your model’s manual first bypassing codes risks water damage or electrical hazards.
Common Brand-Specific E3 Meanings
Bosch dishwashers: Signals low water intake, typically from a clogged inlet hose, kinked line, or faulty water valve.
AEG/Electrolux compact free-standing: Points to a failed heating element unable to warm water for proper sanitation.
AEG integrated compact: Indicates a leak or excess water activating the flood switch in the base.
Other brands (e.g., Candy, generics): Often heating element, thermostat, or sensor issues; sometimes drain problems.
E3 Error Quick Reference Table
| Brand/Model Type | E3 Meaning | Common Causes | First DIY Steps |
|---|---|---|---|
| Bosch (e.g., SHE series) | Low water fill | Blocked hose, bad inlet valve | Check hose kinks, power cycle |
| AEG Free-Standing Compact | Heating element failure | Burnt-out element | Test continuity, call pro |
| AEG Integrated Compact | Leak or excess water | Seals/hoses, float switch | Mop base, shut off water |
| Generic/Candy | Heating or drain fault | Sensor/wiring issues | Reset power, clean filters |
Safe Troubleshooting Steps
- Power reset: Unplug for 5–30 minutes to clear glitches (fixes 50% of false codes).
- Water supply: Confirm faucet open, no kinks, good pressure (20–120 PSI).
- Base check: With water off, tilt and mop any hidden leaks tripping the float.
- Clean filters/hoses: Remove debris affecting flow or sensors.
- Manual lookup: Download “[your brand model] manual PDF” for exact diagnostics.
Never ignore or override E3 risks shocks, floods, or fires. Stop use if water appears.
When to Call a Professional
Handle hoses/valves yourself with basic tools, but heating elements, sensors, or wiring need pros ($150–$400 total). Use authorized techs to preserve warranty. Prevent issues with monthly vinegar cleans, quality rinse aid, and avoiding overloads.
FAQs about Dishwasher E3 Error Codes
1. What causes E3 most often across dishwasher brands?
Heating element failure tops the list (water stays cold, poor cleaning), followed by water supply problems or leaks. Brand manuals specify Bosch leans water-related, AEG heating-focused but all halt cycles for safety.
2. Can I fix a Bosch E3 error myself?
Often yes: power cycle first, then inspect the inlet hose for kinks/blockages and flush debris. Test the water valve with a multimeter (should read 1000–3000 ohms); replacements cost $50–$100 and take 30 minutes with basic tools.
3. Does E3 mean my dishwasher leaked water?
Possibly, especially on AEG integrated models where excess water trips the base float switch. Shut off water/supply immediately, mop thoroughly, and check door seals/hoses before retrying persistent leaks need pro service to avoid shorts.
4. Why won’t resetting power clear the E3 code?
Glitches clear 50% of cases, but hardware faults (bad element, valve, sensor) persist. If reset fails, it’s likely a physical issue requiring part testing/replacement rather than electronics hiccup.
5. Is E3 dangerous to ignore or bypass?
Absolutely—cold water risks bacteria growth (dishes not sanitized), low fill strains pumps, and leaks can flood kitchens causing mold/electrical fires. Codes protect your home; service promptly.
6. How much does E3 repair typically cost?
DIY hoses/valves: $20–$100 parts. Pro heating element/sensor: $150–$400 including labor. Authorized service preserves warranty; shop around but prioritize certified techs for complex electrics.
7. Does E3 appear on premium brands like Miele or Bosch only?
No, common across mid-range (Bosch, LG, AEG) to budget units. Premiums like Miele use F-codes or words; always verify your manual since E3 varies wildly by maker.
8. Can hard water trigger E3 errors?
Indirectly yes scale clogs heaters/sensors, mimicking failures. Monthly vinegar cycles (hot water + 2 cups white vinegar on empty) prevent 70% of buildup-related codes.
9. What’s the first sign before E3 flashes?
Longer cycles, streaky dishes (cold water), no fill sounds, or base wetness. Early maintenance (filter cleans) stops 80% of escalations to full errors.
10. How do I find my exact model’s E3 fix?
Search “[brand] [model number] E3 manual PDF” on the official site (bosch-home.com, aeg.co.uk). User manuals list precise causes/steps avoid generic YouTube guesses that mismatch your unit.
