Can I fix LG dishwasher error code IE myself?

Often, yes. Safe first checks: Be certain the water supply valve is turned ON and the water line is not kinked or bent Check your home water pressure is between 20 and 120 PSI - if it is too low, contact a plumber If you perform all of these checks and the IE error code persists, the unit will require a repair service.

LG Dishwasher error code IE

What it means

Water inlet error - not enough water is reaching the tub. LG says the level of water in the unit did not get high enough after 10 minutes of filling.

Likely causes

The water supply valve is turned off, or the water line is not connected
The water supply hose is pressed, bent or kinked
Water pressure is too low - LG says it must be between 20 and 120 PSI
The drain hose outlet is installed lower than the base of the dishwasher, so water is siphoned out
Parts of the dishwasher have frozen in cold weather
The dishwasher is not level

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.

Safe first checks

Be certain the water supply valve is turned ON and the water line is not kinked or bent
Check your home water pressure is between 20 and 120 PSI - if it is too low, contact a plumber
Make sure the end of the drain hose is over 10 inches (almost 12 inches) above the bottom of the dishwasher, so water is not siphoned out
Thaw any frozen parts by soaking a towel in warm water and wrapping it around the frozen area
Check the dishwasher is level

When to call a pro

If you perform all of these checks and the IE error code persists, the unit will require a repair service.

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.
