LG Dishwasher Not Cleaning, Draining, or Starting in Dubai? Here's Why

 

LG dishwashers are a popular choice in Dubai homes, particularly in newer apartments and villas where kitchens are designed to accommodate built-in appliances. They are generally reliable, but a few faults appear repeatedly in the UAE's hard-water environment. Here is a practical guide to the most common issues and what professional LG dishwasher repair involves.

Common LG Dishwasher Problems:

1. Dishwasher Not Cleaning Properly

If dishes are coming out still dirty after a full cycle, the problem is almost always one of the following: blocked spray arms, a clogged filter, insufficient detergent, or a faulty wash pump.

Start with the filter: LG dishwashers have a cylindrical filter at the base of the tub that traps food particles. In Dubai, with hard water accelerating mineral buildup, this filter can become clogged surprisingly quickly. Remove it, rinse it under a tap, and use a soft brush to clear any blocked mesh.

Check the spray arms: Remove the upper and lower spray arms (they usually unclip or unscrew) and hold them up to the light. If any of the small holes are blocked with limescale or food debris, soak the arms in white vinegar for 30 minutes and use a toothpick to clear each hole.

2. Dishwasher Not Draining

Standing water in the bottom of the dishwasher after a cycle is completed is a drainage fault. The most likely causes are a blocked drain filter, a kinked drain hose, a blockage where the drain hose connects to the sink waste, or a failed drain pump.

Quick check: Ensure the drain hose is not kinked behind or beneath the machine. Check that the connection to the sink's waste pipe is clear. Clean the filter as described above. If water still does not drain, the pump needs professional inspection.

3. Dishwasher Not Starting

An LG dishwasher that receives power (the display is active) but does not start a cycle when commanded is typically experiencing one of these faults: the door latch is not engaging properly, the child lock is active, or a control board fault has occurred.

Check first: Look for a lock icon on the display — this indicates the child lock is active. On most LG models, hold the designated button (usually marked with a lock icon) for 3 seconds to deactivate it. If the display shows no fault but the door simply does not latch, the door catch needs replacement.

4. Dishes Not Drying Properly

LG dishwashers use a heated dry cycle that relies on a heating element and a vent fan. If dishes are consistently wet after a full drying cycle, the heating element or vent fan motor may have failed.

Also check: Plastic items never dry as well as glass or ceramic in dishwashers — this is normal physics, not a fault. Ensure you are using rinse aid, which dramatically improves drying performance.

5. LG Dishwasher Making Unusual Noises

A dishwasher that makes grinding, rattling, or humming noises during operation is usually experiencing one of these issues:

• Grinding: A foreign object (broken glass, seeds, bone fragment) trapped in the pump

• Rattling: Cutlery or dishes not properly secured in the rack, touching the spray arms

• Constant humming with no water movement: Wash pump motor failure

Foreign objects in the pump can cause serious damage quickly — if you hear grinding, stop the cycle immediately and call a technician.

6. LG Dishwasher Error Codes

LG dishwashers communicate faults through error codes. The most common are:

• AE / E1 — Water leak detected (the anti-flood sensor has triggered)

• IE — Water inlet error (check supply tap and inlet hose)

• OE — Drainage error (blocked filter or drain pump fault)

• HE — Heating error (heating element fault)

• tE — Temperature sensor error

An AE (water leak) error should be treated urgently — turn off the water supply to the dishwasher and call a technician before using the machine again.

LG Dishwasher Maintenance Tips for Dubai:

• Run a hot maintenance cycle monthly with a dishwasher descaler — limescale is aggressive in Dubai's water

• Clean the filter every 2 weeks with heavy use

• Always use rinse aid and keep it topped up

• Check the door seal monthly for mould or cracking

• Leave the door slightly ajar after each cycle to allow the interior to dry and prevent odour

LG Washing Machine Error Codes: What Every UAE Owner Needs to Know:
