What is the average lifespan of an LG dishwasher?
LG dishwashers (including model LDT7808SS) typically last 10 to 15 years with normal household use. Consistent maintenance, correct detergent use, and keeping the filtration and spray system clean are the biggest factors in reaching the high end of that range; see the care guidance in the LDT7808SS owner’s manual.
- Filter and sump cleanliness: food debris left in the filtration area strains the wash system.
- Water quality: hard water can cause mineral buildup on internal parts.
- Loading habits: blocked spray arms and overloading reduce cleaning and increase wear.
- Detergent and rinse aid use: too much detergent can leave residue; rinse aid helps drying on hybrid-dry designs.
- Leak prevention: keeping door seals clean helps prevent moisture damage around the door.
Use this simple routine to help your LDT7808SS run longer:
| Task | How often | Why it helps |
|---|---|---|
| Clean filters | Monthly (more often with heavy use) | Prevents poor wash performance and drain strain |
| Clean spray arms | Every 2 weeks to monthly | Keeps water jets strong and consistent |
| Run a cleaning cycle | Monthly | Reduces odor and mineral film |
| Wipe door seals | Monthly | Helps prevent leaks and mold |
If your dishwasher is approaching the end of its typical lifespan, these are common signs that repairs may become more frequent:
- Repeated draining problems even after cleaning filters and checking the drain path
- Persistent leaks around the door or tub edge
- Poor cleaning results with normal loading and correct cycle selection
- Unusual motor noises during wash or drain
A dishwasher that is maintained well usually cleans better, dries better, and avoids the kind of clogs and leaks that shorten the life of key components like the pump, motor, and inlet valve.

What is the most common problem with LG dishwashers?
For the LG LDT7808SS, the most common issues we see are water-related: not draining (often tied to an OE drain error) or not filling (often tied to an IE inlet error). Many times, the fix starts with cleaning the filters and checking for kinks or clogs in the drain path; see the LDT7808SS owner’s manual.
- Clean the filter assembly and remove food debris.
- Check the drain hose for kinks, pinches, or clogs.
- If connected to a garbage disposal, confirm the disposal knockout plug was removed.
- Make sure the water supply valve is fully open and the inlet hose is not kinked.
- Verify the door closes and latches fully before starting a cycle.
- Use only automatic dishwasher detergent (hand soap causes oversudsing and drain issues).
| Symptom | What it usually points to | What to do first |
|---|---|---|
| Standing water after a cycle | Drain restriction or drain pump issue | Clean filters; inspect drain hose; consider the dishwasher drain pump ABQ75742505 if the hose and filters are clear |
| Dishes not cleaning well | Clogged spray arm holes or weak circulation | Clean spray arms; check loading; consider the LG dishwasher pump and motor assembly AGM30016301 if wash pressure seems low |
| Won’t fill or fills slowly | Water supply restriction or inlet valve issue | Confirm hot water supply and pressure; inspect inlet hose; consider the dishwasher water inlet valve 5221DD1001E |
| Error codes showing | A specific monitored fault | Use the LG dishwasher error codes guide to match the code to next steps |
Drain and fill problems can leave dirty water in the tub, cause poor wash results, and trigger repeated error codes. Catching clogs early (filters, hoses, spray arms) helps protect the pump, motor, and control system.

What are the disadvantages of the LG dishwasher?
For the LG LDT7808SS dishwasher, the main disadvantages are usually tradeoffs from its energy-efficient hybrid drying system: plastics can stay wet without rinse aid, some cycles can run longer than older heat-dry designs, and loading can feel picky depending on dish shape. See the LDT7808SS owner’s manual for cycle and option details.
- Drying performance on plastics: Hybrid drying relies on retained heat and airflow, so plastic and nonstick items often need extra help.
- Rinse aid is strongly recommended: Without it, water can remain on dishes and in the tub.
- Longer cycle times: Auto and Normal can run longer because the dishwasher adjusts for soil level and water temperature.
- Loading fit complaints: Tall items, wide bowls, and odd cookware can interfere with spray arm rotation or rack spacing.
- Normal operating noises: Water fill, spray action, and draining can be noticeable at certain points in the cycle.
- Use rinse aid and increase the rinse aid setting if you see spotting or poor drying.
- Select Extra Dry and use Night Dry when leaving dishes overnight.
- Run the hot water at the sink briefly before starting if the dishwasher is far from the water heater.
- Clean filters and spray arms regularly to keep water flow strong.
| Concern | Best cycle/option to try | Why it helps |
|---|---|---|
| Wet plastics | Extra Dry + rinse aid | Improves sheeting and adds drying time |
| Dishes still damp overnight | Night Dry | Vents humid air after the cycle |
| Poor cleaning | Auto or Heavy + High Temp | Boosts wash action and temperature |
If you’re getting repeated drain problems, standing water, or loud grinding during drain-out, that’s not a normal tradeoff. A common part involved in draining is the dishwasher drain pump ABQ75742505.
Most “cons” are the result of energy-saving design choices. With rinse aid, the right options, and routine maintenance, the LDT7808SS typically delivers strong cleaning with fewer day-to-day frustrations.
