Error code
Dishwasher error code HE
LG dishwasher error code HE: The heater on these machines does two jobs — it lifts the wash water to temperature and, on the models with heat dry, it helps the drying at the end. Every spelling LG publishes for it, which machines can raise it, and what to do next.

What we can confirm
Code HE, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
HE
The heater on these machines does two jobs — it lifts the wash water to temperature and, on the models with heat dry, it helps the drying at the end. When the element or its circuit fails, the machine can still wash, badly, in water it cannot bring up to temperature, and it will tell you rather than pretend. Poor cleaning with no code and poor cleaning with this code are two different calls, which is why the code is worth writing down before the power goes off.

What it narrows down to
The water is not getting hot, or is getting hot in the wrong way

What else belongs to the dishwashers
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
The machine has found water where it should not be, and is protecting the floor
Not enough water is arriving, or it is arriving too slowly
The water that went in has not come out
The machine cannot tell how hot the water is
The motor that drives the spray arms is overloaded or stalled
The machine cannot agree with itself about how much water is in the tub
There is far more foam in the tub than the machine can wash through
The pump that switches the water between the spray levels is not responding
Not an error — the panel has been locked
The fan in the drying system has stopped
The drying system cannot reach or hold its temperature
The door that should open itself at the end of the cycle has not

About Dishwasher error code HE
What HE means on this make
The heater on these machines does two jobs — it lifts the wash water to temperature and, on the models with heat dry, it helps the drying at the end. When the element or its circuit fails, the machine can still wash, badly, in water it cannot bring up to temperature, and it will tell you rather than pretend.

The other ways LG prints this one
HE · HE1 · H E
LG publishes a condition and then every string that can stand for it, and which one your machine shows depends on the panel it was built with — OE, E03 and E21 are one condition on a washer, and Er dS, F dS and r dS are one sensor on different evaporators. They are one page here, so whichever of them you searched for, this is the right page.
Where this appears, and why not to clear it
On the appliance's own display. LG reports errors two ways: machines with a digital display show a code, and the laundry machines without one blink their indicator lights instead. Both are published by the maker and both are on this site. Photograph what the panel shows before cutting the power. On a refrigerator you can also force the last code back onto the display by holding Freezer Temperature and Express Frz together for three seconds — LG documents that, and it is the one thing that makes a first visit more useful. A code that has been reset is information a technician no longer has.
What to do about it
- Check the incoming water is genuinely hot — run the sink tap for thirty seconds first.
- Note whether things are also coming out wet, which points at the same circuit.
- Cycle the power at the breaker.
- A returning HE is a visit: the element is inside the tub and is not a homeowner part.
Where this goes next
The job this usually becomes is diagnostic visit, and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 419-0291 and describe what the panel is doing before booking anything.
