LG Dishwasher Error Code CR

Not a faultReviewed November 2026Checked against manufacturer documentation

What this code means

CR: Test mode is active — not an error

CR means the machine has been put into its service test mode, usually by a button combination pressed during a repair or by accident. It is not reporting a fault. A full power reset is normally all it takes to get back to normal operation.

Fix level

Not a fault

This is a status display, not a fault. No repair is needed.

Time to run the checks

About 15–30 minutes

For the 3 checks on this page — not a full repair.

You may need

No special tools

The checks below use basic household items only.

Parts that may be involved

None usually

Parts are model-specific; see the note below before ordering.

Common causes

Test mode started by a service button combination
Control glitch after a power interruption

What to check, in order

Safety first. Switch the dishwasher off and unplug it (or turn off its breaker) before checking hoses or filters. Expect water in the bottom of the tub and around the filter; keep a tray and towel ready. If you are not comfortable with any step, stop and call a technician.

Turn the dishwasher off and cut power at the breaker or plug for ten to fifteen minutes
Restore power and start a normal cycle; the display should behave as usual
If CR keeps coming back on its own, mention it when you book any other service — the control may need attention

Clear the code and test

Fix what the checks above found first — a filter cleaned, a hose straightened, the spray arms freed. Clearing the code without fixing the cause only brings it back.
Close the door, plug the dishwasher back in (or restore its breaker) and make sure the water tap is open.
Run the shortest programme and stay nearby for the first minutes, watching for leaks and listening for the drain pump.
If the programme finishes with no code, the fault is cleared. If the code returns, write down the code and when it appeared before calling a technician — it speeds up the diagnosis.

When to call a professional

This display is not a fault, so there is normally nothing to book. Call a technician only if the machine also behaves abnormally, or if any of these apply:

The code comes back after you have run the checks and a test cycle.
You smell burning, see sparks or scorch marks, or the breaker trips.
Water is leaking and you cannot stop it at the tap.
The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.

When you call, give the brand, the code CR, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
