LG LDP7708ST/00 dishwasher Parts

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.

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)

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.

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.

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.

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.

• 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

1. Clean the filters and remove debris (this is the top cause of poor wash and drain complaints).
2. Inspect the drain hose for kinks and make sure the sink connection is not blocked.
3. Check for oversudsing: only use automatic dishwasher detergent (hand dish soap can cause excessive suds and performance problems).
4. Confirm the dishwasher is level; leveling problems can contribute to leaks and standing water.
5. Improve drying: use rinse aid and consider higher-temp and extra-dry options, especially for plastics.

If cleaning and hose checks do not solve it, these parts commonly match the symptoms:

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.

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).

• 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.

Many LG dishwasher “error codes” point to a real issue. Here are common ones referenced in the troubleshooting and installation guidance:

For the full list and model-specific button sequences, use the LDP7708ST owner's manual.

• 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.

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.

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.
