What is the life expectancy of an LG dishwasher?
Most LG dishwashers, including the LG LDP7708ST, typically last 9 to 12 years with normal home use. With consistent cleaning and prompt fixes for draining, leaking, or wash-performance issues, it’s common to reach the upper end of that range.
Typical lifespan and what affects it
A dishwasher’s service life depends more on conditions and maintenance than brand alone. The biggest factors are:
- Water quality (hard water speeds up mineral buildup)
- How often you run it (daily use wears pumps, seals, and racks faster)
- Filter and spray arm cleaning habits
- Proper detergent and rinse aid use
- Fixing small problems early (slow drain, poor cleaning, door leaks)
What the LDP7708ST warranty tells you (useful clue)
Your LDP7708ST owner's manual shows longer coverage on key components (for example, extended coverage on the Direct Drive motor and certain other major items). That kind of coverage is a strong indicator the dishwasher is designed for long-term use when it’s maintained.
| Item (example) | What it suggests | What you should do |
|---|---|---|
| Motor and controls | Built for years of cycling | Keep filters clean; avoid running with standing water |
| Stainless tub/liner | Designed to resist corrosion | Address leaks quickly; keep door seal clean |
| Racks and rollers | Wear items over time | Replace worn rollers or rails to prevent rack damage |
Maintenance that extends life (high impact)
These steps prevent the most common “end-of-life” failures like poor cleaning, odors, and drain problems:
- Clean the filter area regularly and remove debris
- Rinse and clear spray arm holes if you see poor wash coverage
- Keep the door gasket clean and check for tears or flattening
- Run a dishwasher cleaner cycle periodically to reduce grease and mineral buildup
- Don’t ignore slow draining; it strains the drain system
If you’re dealing with a drain issue on this model, the dishwasher drain pump ABQ75742501 is one of the common repair parts to check or replace.
Why it matters
Knowing the typical 9 to 12 year lifespan helps you decide whether to repair or replace. If your LDP7708ST is under about 8 years old, repairs like a pump, seal, or dispenser are often cost-effective compared to replacing the whole dishwasher.

What is the most common problem with a LG dishwasher?
The most common LG dishwasher problem is a drain issue: water stays in the tub because the filters or drain path are clogged, or the drain hose is kinked. On the LG LDP7708ST, start by cleaning the filters and checking the drain hose, then confirm any displayed error code in the LDP7708ST owner's manual.
Most common issues we see (and what usually causes them)
- Not draining (often shows a drain-related error code): clogged filters, clogged air gap or disposal connection, kinked or frozen drain hose
- Water inlet problem (fills slowly or not at all): kinked inlet hose, water supply turned off
- Leaks: door not sealing, unit not level, loose hose connections
- Poor cleaning: spray arms blocked, overloading, items blocking spray arm rotation
- Poor drying: no rinse aid, plastics and nonstick items holding water droplets
Quick checks you can do in 10 to 20 minutes
- Clean the filters and remove debris (this is the top cause of poor wash and drain complaints).
- Inspect the drain hose for kinks and make sure the sink connection is not blocked.
- Check for oversudsing: only use automatic dishwasher detergent (hand dish soap can cause excessive suds and performance problems).
- Confirm the dishwasher is level; leveling problems can contribute to leaks and standing water.
- Improve drying: use rinse aid and consider higher-temp and extra-dry options, especially for plastics.
When a part is the likely fix
If cleaning and hose checks do not solve it, these parts commonly match the symptoms:
| Symptom | Common suspect | Example part for LDP7708ST |
|---|---|---|
| Water remains in tub | Drain pump not pumping out | Dishwasher drain pump ABQ75742501 |
| Leaking at the door | Worn or deformed gasket | Dishwasher door seal 3920DD3002D |
| Dishes not clean on bottom rack | Lower spray arm clogged or damaged | LG dishwasher spray arm, lower AGB73932401 |
Why it matters
Drain and fill problems can trigger repeated stopping, longer cycle times, and poor results. Keeping filters clean, using the right detergent, and maintaining good water temperature and rinse aid use helps the LG LDP7708ST wash and dry the way it was designed.
For code-specific troubleshooting, we also recommend checking LG dishwasher error codes. If you need to order replacement parts, use the parts list for your model or search by model number on Sears PartsDirect.

How to reset LG dishwasher error code?
To reset an error code on your LG LDP7708ST dishwasher, we recommend powering the dishwasher off, then back on, and running a Cancel or drain function to clear any leftover water. If the code returns, the dishwasher is detecting a condition that still needs to be fixed (not just a control glitch).
Quick reset steps (safe first)
- Press Power to turn the dishwasher off.
- Wait 10 to 15 seconds.
- Press Power to turn it back on.
- If the dishwasher is mid-cycle or has standing water, run Cancel/Drain (wording varies by cycle and panel).
- Start a short cycle and watch for the code to reappear.
What the code usually means (common LG examples)
Many LG dishwasher “error codes” point to a real issue. Here are common ones referenced in the troubleshooting and installation guidance:
| Code | What it points to | What to check first |
|---|---|---|
| OE | Drain problem | Kinked/pinched drain hose, clogged waste tee/garbage disposal knockout, blocked filter |
| IE | Fill problem | Kinked water supply line, water supply turned off |
| CL | Control Lock is on (not a failure) | Turn off Control Lock using the correct button combo |
For the full list and model-specific button sequences, use the LDP7708ST owner's manual.
Fix-first checks that stop the code from coming back
- Drain hose routing: Make sure it is not kinked or crushed behind the dishwasher (a common OE cause).
- Disposal connection: If connected to a garbage disposal, confirm the knockout plug was removed.
- Filter and sump area: Remove debris that can restrict draining and trigger OE.
- Door latch: A door that is not fully latched can prevent operation and create “won’t run” symptoms.
- Control Lock: If CL is showing, disable Control Lock before troubleshooting anything else.
When a part is likely involved
If you have repeated OE draining errors after clearing hose and filter restrictions, the drain system is the next place to look. A common replacement part is the dishwasher drain pump ABQ75742501.
Why it matters
Resetting clears the display, but the dishwasher’s error-monitoring system is designed to bring the code back if the underlying drain, fill, or control condition is still present. Fixing the root cause prevents repeat shutdowns and protects wash performance.
