When to Call a Professional

Call a professional if the heating element tests good but the error persists, if you're uncomfortable working with electrical components, or if the control board needs replacement. Also contact a pro if multiple error codes appear simultaneously, as this may indicate a more complex system failure.

Frequently Asked Questions

Why does my Samsung dishwasher show HE error code?
The HE error indicates your dishwasher's heating system isn't working properly. This could be due to a faulty heating element, broken temperature sensor, loose electrical connections, or issues with the control board.
Can I still use my dishwasher with HE error code?
It's not recommended to use the dishwasher with an HE error as it won't heat water properly. This means dishes won't be sanitized and may not get clean, especially with greasy or dried-on food.
How much does it cost to fix Samsung dishwasher HE error?
Costs vary depending on the part needed. A heating element typically costs $50-150, while professional labor runs $100-200. Temperature sensors cost $20-50. DIY repairs can save significantly on labor costs.
How long should a Samsung dishwasher heating element last?
A dishwasher heating element typically lasts 8-12 years with normal use. Hard water, frequent use, and mineral buildup can shorten this lifespan. Regular maintenance helps extend component life.
Will unplugging my Samsung dishwasher fix the HE error?
Unplugging for 5-10 minutes can sometimes clear temporary sensor errors or control board glitches. However, if the heating element or temperature sensor is actually faulty, a reset won't fix the underlying problem.
