My dishwasher was working fine, then suddenly it showed error E3. After that, it completely stopped refilling with water.
Now it won’t start a proper cycle at all. If you’re dealing with the same issue, here’s what’s likely happening and how to fix it.
Quick Answer
If your dishwasher shows error E3 and won’t refill, the problem is usually:
- Faulty wash motor or circulation system
- Drain issue preventing refill
- Sensor or control error blocking the cycle
Step-by-step: How to fix E3 error and no water refill
Step 1: Reset the dishwasher
Start simple:
- Turn off power
- Unplug for 5–10 minutes
- Restart
This clears temporary faults.
Step 2: Check if water is still inside
Dishwashers won’t refill if water hasn’t drained.
- Open the unit
- Look for standing water at the bottom
If water is present → drain issue is blocking refill.
Step 3: Inspect the drain system
Check:
- Filter and sump for debris
- Drain hose for clogs
- Drain pump operation
If it can’t drain properly, it won’t allow new water in.
Step 4: Check the wash (circulation) motor
E3 is often linked to the motor.
- Listen for motor noise during cycle
- If silent or struggling → possible failure
A bad motor can stop the cycle early and trigger errors.
Step 5: Inspect the water inlet system
If draining is fine but no refill:
- Check water inlet valve
- Clean inlet filter
- Ensure water supply is on
A blocked valve prevents water entry.
Step 6: Check sensors and control system
Dishwashers rely on sensors to allow refill.
- Water level sensor
- Pressure sensor
If faulty, the machine may think it’s already full.
Step 7: Consider control board issues
If all else checks out:
- Control board may not be sending signals
- Can cause both E3 error and refill failure
Extra tips and best practices
- Clean filters regularly
- Avoid food debris entering system
- Run maintenance cycles
- Ensure proper installation of drain hose
Common mistakes to avoid
- Ignoring drainage issues
- Replacing parts without testing
- Overlooking simple blockages
- Assuming it’s only a water supply issue
FAQs
What does E3 mean on a dishwasher?
It often indicates a motor or circulation problem, depending on the model.
Why won’t my dishwasher refill with water?
Because it may think there’s still water inside or detect a fault.
Can a drain issue cause E3 error?
Yes. Poor drainage can trigger errors and stop refill cycles.
Conclusion
If your dishwasher shows E3 error and won’t refill, start by checking the drain system and motor. These are the most common causes.
Work step-by-step, and you’ll likely fix the issue without replacing major parts.
