# LG diagnostic visit

### What you can have ready before we arrive

Three small things make the visit shorter, and you can do all of them before we knock. Find the model number — inside the fresh food door on a refrigerator, on the door frame of a washer, under the lid on most dryers, on the left jamb of an oven — and send it when you book, because on this make the same code reads differently on a front loader than on a pedestal washer. Leave the machine plugged in: the display clears when power is cut and the condition does not, so a code you have already seen is worth far more on the screen than in your memory. And write down the week it started and what changed in the house that week.

What this involves

The model number and whatever the appliance is reporting, read before anything is opened

Blinking-light patterns included, because LG documents them and that makes them codes

Written findings and a from-price before any part is ordered

Read what the appliance is telling you

The code, or the exact pattern of blinking lights on a machine with no display. On a refrigerator the last code can be forced back onto the display by holding Freezer Temperature and Express Frz together — worth doing before anybody cuts the power, because the display clears and the condition does not.

Establish which machine this actually is

LG sells four fuels of range, three kinds of dryer and five shapes of washer, and several codes mean different things across them. dE1 on a SideKick pedestal is a drawer; dE on a front loader is a door. The model number decides which reading applies.

Hear the history

When it started, whether it was sudden, what changed in the house that week. A filter change, a power cut or a machine that was moved explains a great many of these before anything is opened.

Test rather than assume

Meters on the parts the reading points at. A code narrows the field; it does not name the part, and quoting from a code alone is guessing with extra confidence.

Put it in writing

What it is, what it takes, and a from-price. Nothing is opened, ordered or charged before you have agreed to it.

### Do I need to be there the whole time?

Someone over eighteen needs to let us in and stay in the home while we work. Beyond that you are free to get on with your day. We will find you before anything is decided, and nothing is opened, ordered or charged until you have agreed to it in writing.

### What if the appliance is not showing anything today?

That happens often, especially with anything that comes and goes in the heat. Tell us what you saw and when — an intermittent condition is diagnosed on measurements and history rather than on a code that has cleared itself, and we would rather book you for the morning after a hot night than chase a machine that behaves while we watch.
