What the Error Code Means
Error code E09 generally means the dishwasher detected that water is not heating as expected during the cycle.
It points to a heating or temperature problem rather than a single confirmed failure.
Common Symptoms You May Notice
- Dishes feel cool, greasy, or not fully dried at the end of the cycle.
- The cycle stops early or runs unusually long.
- The display shows E09 and the program does not finish normally.
Most Common Causes (From Least to Most Serious)
- Incoming water is too cold: If the water entering the dishwasher is very cold, the machine may not reach target temperature in time.
- Low water flow or restricted circulation: When water cannot move normally, heating can be uneven and trigger the alert.
- Heating performance is outside the expected range: In some cases the dishwasher detects a heating performance issue and pauses for safety.
Safe Things You Can Check Yourself
- Run hot water at the sink for a minute before starting a cycle so the dishwasher fills with warmer water.
- Confirm the water supply valve under the sink is fully open.
- Power cycle the dishwasher: turn it off at the control panel, wait a full minute, and turn it back on.
If at any point this feels unsafe or unclear, stop and contact a professional.
When to Stop and Call for Service
- The E09 code returns after warm-water and supply checks.
- The dishwasher stops mid-cycle and the water never heats.
- You notice leaks, electrical smells, or repeated shutdowns.
Typical Repair Cost Range
$200-$500 is typical for professional diagnosis and repair of dishwasher heating issues, depending on the cause and parts involved.
Costs vary by region, model, and provider. Request an estimate before approving any repair.
