Samsung Dishwasher error code HE

Q: Can I fix Samsung dishwasher error code HE myself?

Often, yes. Safe first checks: Empty the dishwasher Add detergent, and then run a Normal cycle If the error still occurs, switch off the power at the circuit breaker and request service from Samsung. Heater and sensor work inside the machine is for a technician.

What it means

Heater error - the temperature inside the dishwasher is being detected incorrectly.

Likely causes

The temperature inside the dishwasher is being detected incorrectly

Safety first: switch the appliance off and unplug it (or turn it off at the circuit breaker) before you check anything. If water is involved, close the water supply valve too. Never open panels or touch internal wiring. Anything that involves gas lines, refrigerant or sealed systems, or mains-voltage wiring is a job for a professional - not a home fix.

Repair or replace?

Try the safe checks first - many codes clear with a clean filter, a straight hose or a balanced load, and those cost nothing. If the code comes back, a service call typically costs $50-$150 for the visit and diagnosis (Angi puts an average service call at $50-$100; Sears lists a $90-$150 diagnostic fee). Get the full repair quote before you decide. If the machine is old and the quote is a large part of the price of a new one, replacing usually makes more sense than repairing.
