LG Dishwasher Dishes Stay Wet After the Cycle: What to Check

Wet glasses and puddles on top of bowls are one of the most common complaints in any kitchen with a modern dishwasher, and it is often not a defect at all. Drying in a dishwasher is a slow process that depends on heat, airflow and the way dishes are shaped. Still, when a machine that used to dry well begins to leave everything damp, something has changed, and the change is worth tracking down.

How a dishwasher dries what it washed

After the final rinse the machine has to remove a film of water from every surface. Some designs lean on residual heat in the dishes and tub; the water evaporates and the vapor leaves through a vent or condenses on the tub wall and runs down. Others add a heating element at the base, and models in the Dynamic Heat Dry group also move air with a fan. Whatever the design, the end of the cycle depends on three things working together: heat, moving air, and a clear path for moisture to escape.

Plastic is the usual exception. Cups, containers and plastic lids hold less heat than glass or ceramic, so water beads on them and stays. A little damp plastic in an otherwise dry load is normal behavior and should not by itself trigger a service call.

Likely reasons, from simplest to most serious

Settings and rinse aid

If a heated dry or extra dry option exists on your panel and was switched off, the load will come out wetter. Rinse aid matters just as much: it lowers surface tension so water sheets off instead of clinging. An empty rinse-aid dispenser is the number one reason glasses come out spotted and wet, and refilling it takes seconds.

Loading

Cups tipped upward, bowls facing flat, and nested dishes all trap water in pockets. Angle items downward, leave gaps, and keep a bowl from covering another. Overloading blocks the airflow and the spray, so nothing dries properly.

Water that never fully left

If the drain is slow, the tub still holds moisture when drying starts. Look at the tub floor after the cycle. Standing water points to a clogged drain screen, a blocked drain hose, or a disposal connection issue, and the OE code means the tub did not drain fully. That is a drain problem first and a drying problem second.

Heater, fan and sensor

A heating element that no longer warms the water leaves dishes cool at the end, and the HE heater error exists for this. A temperature sensor that misreports can shorten or skip the heated phase, which is what tE signals. On Dynamic Heat Dry units, F31 flags a dry fan that is not turning and F35 flags temperatures the machine cannot measure during the dry phase. A code on the display is a strong hint that the drying hardware, not your loading, is the cause.

Door seal and venting

A gasket that is torn or folded, or a door that does not close squarely, lets humid air out early and cool air in. If you often find water dripping along the door edge or the cabinet front, close the door slowly and watch that the gasket seats evenly all the way around.

Checks that are safe to do yourself

• Refill the rinse-aid dispenser and run one cycle with a normal, sensibly loaded tub.
• Select the heated dry or extra dry option if your panel offers one.
• Crack the door a little at the end of the cycle, or let the machine rest with the door open, to let steam out.
• Clean the filter and the drain screen in the tub. Rinse them under the tap and put them back fully seated.
• Inspect the door gasket for debris, folds or splits.
• Write down any code shown at the end of a cycle, even if it clears on its own.

When this points to a repair

If a clean, level, correctly loaded machine with rinse aid and the right settings still leaves everything wet, and especially if the inside feels cold at the end of the cycle, the heater, fan or sensor may be at fault. Do not take the machine apart. A technician can test each part in turn, which is faster and safer than guessing. If you also notice that the dishes are dirty and not only wet, compare with the upper-rack cleaning guide, because a weak spray and weak drying sometimes share a cause. Smell is another clue; the odor guide covers moisture that lingers in the tub.

Booking and what to have ready

When you ask for a visit, give the model number, the settings used, and whether you see standing water or codes. We diagnose first, explain what we found, provide a written estimate and repair nothing without your approval. More on how these visits work is on our LG dishwasher repair page, and the family overview sits at LG dishwashers. If the model plate on your door is hard to read, this guide to locating it helps. Models we see often include LDNTC326 and LDNPQ44H.

A quick way to tell wash trouble from drying trouble

Run a plain test. Put in a handful of clean glasses and bowls, add rinse aid, use the normal cycle with heated dry if offered, and open the door when the end tone sounds. Glass that is hot to the touch but covered in droplets points toward airflow or rinse aid. Glass that is only warm and tub walls that feel cool suggest the heat phase did not do its job. Dishes that are both wet and gritty suggest the wash itself is weak, which is a different problem.
