LG LDTS5552D/00 dishwasher Parts

On your LG dishwasher, the model number is printed on the rating label located just inside the door opening, typically along the left-hand side. For your unit, you’re looking for LDTS5552D (often shown with a suffix like /00).

Where to look (fast checklist)

• Open the dishwasher door fully.
• Look along the inside edge of the tub opening.
• Check the left-hand side first.
• Find the rating label (it lists model and serial).
• Write down the model number and serial number exactly as shown.

What the label info means

Label item	What it’s used for	Why you need it
Model number (example: LDTS5552D/00)	Identifies the exact dishwasher version	Ensures correct parts and diagrams
Serial number	Identifies production run	Helps match revisions and service info

Why it matters

LG often makes small design changes within a model family. Using the exact model from the rating label helps us match the right dishwasher parts (like a control panel, drain pump, or water inlet valve) the first time.

Helpful next step

Use the model number from the label to confirm operating details and feature locations in the LDTS5552D owner’s manual.

Some common disadvantages owners notice with the LG LDTS5552D dishwasher are slower or weaker drying on plastics, cycle-time expectations (longer cycles on some settings), and occasional performance issues tied to water temperature, loading, or wash system components. We use the LDTS5552D owner's manual to match settings and care steps to your exact model.

Most common drawbacks (and what usually causes them)

• Plastics stay wet: water beads on plastic and nonstick surfaces; drying improves with rinse aid and dry options.
• Drying depends on hot water: if the unit starts with cool water, drying results drop.
• Mineral film or cloudy glassware: often hard water plus too much detergent.
• Interior layout tradeoffs: large pans or tall items can block spray patterns if loaded poorly.
• Reliability complaints usually trace to a few systems: fill, wash circulation, draining, or door-latch sensing.

Settings and habits that reduce the “downsides”

The manual guidance for LG dishwashers is clear: drying and spotting are strongly affected by rinse aid, water temperature, and detergent amount.

• Run the hot water at the sink before starting a cycle so the dishwasher fills with hot water.
• Use rinse aid; if results are still weak, increase the rinse aid level (the manual notes level 2 is default and level 3 uses more).
• For plastics, use Extra Dry or Night Dry when available, and let the dry cycle finish before opening the door.
• If you see cloudy film, reduce detergent, add an extra rinse, and consider a hard-water booster.

When a “disadvantage” is actually a part problem

If performance changes suddenly (not gradually), a failing part is more likely than a design drawback.

Symptom	What it often points to	Example part for LDTS5552D
Not filling or fills slowly	Water supply issue or inlet valve	Dishwasher water inlet valve 5221DD1001E
Poor wash pressure, weak spray	Circulation pump or diverter issue	LG dishwasher pump and motor assembly AGM30016301
Won’t start unless door is just right	Door latch sensing/lock issue	Dishwasher door lock AGM76209501

Why it matters

Most “LG dishwasher disadvantages” are really setup and usage sensitivities (hot water, rinse aid, loading) that affect modern low-water dishwashers. Dialing those in usually fixes drying, film, and cleaning complaints without replacing parts.

The most common issues we see with LG dishwashers like model LDTS5552D are poor cleaning or drying from clogged filters or spray arms, plus drain problems from blockages in the sump or drain path. Many symptoms show up as an error code; use the LDTS5552D user manual to match the code to the fix.

Most common symptoms and what usually causes them

• Not cleaning well: clogged filters, blocked spray arm holes, low water temperature
• Not drying well: rinse aid empty or set too low, plastics holding water, door opened too soon
• Not draining: food debris in filters/sump, kinked drain hose, drain pump issue
• Stops mid-cycle or won’t start: door not latching, control sensing a fault, water supply issue
• Leaks or water in base: door seal wear, oversudsing, leveling problems

Quick checks we recommend first (10 to 20 minutes)

1. Turn off power at the breaker, then inspect and clean the filters and sump area.
2. Check the lower spray arm for clogs and free movement; replace if cracked or warped.
3. Run the hot water at the sink before starting a cycle if the dishwasher is far from the water heater (helps maintain consistent hot water).
4. Confirm you are using automatic dishwasher detergent only (hand dish soap can cause oversudsing and errors).
5. Verify rinse aid is filled; LG notes rinse aid improves drying, and you can increase the rinse aid level if needed.

Parts that commonly relate to these problems

Problem	What to inspect	Example part for LDTS5552D
Not draining	Kinks/clogs, pump operation	Dishwasher drain hose AEM74333104 or dishwasher drain pump ABQ75742501
Not filling	Water supply, valve screen, valve	Dishwasher water inlet valve 5221DD1001E
Poor wash action	Circulation, diverter function	LG dishwasher pump and motor assembly AGM30016301 or dishwasher diverter motor 4681ED3001D
Leaks at door	Seal condition, alignment	Dishwasher door seal 3920DD3002D

Why it matters

Most “big” dishwasher complaints trace back to water flow and temperature: if the unit cannot fill, circulate, heat, or drain correctly, cleaning and drying performance drops fast. Regular filter cleaning and correct detergent and rinse aid use prevent many repeat problems.

For code-based troubleshooting, we also use the LG dishwasher error codes reference to narrow the cause quickly.

LG dishwashers typically last 10 to 15 years with normal household use. For the LG LDTS5552D, consistent maintenance (cleaning filters, using rinse aid, and ensuring hot water supply) is what most often determines whether you land closer to 10 years or closer to 15.

What affects lifespan the most

• Water quality and temperature: Hot water at the start of the cycle reduces strain and improves cleaning.
• Routine cleaning: Keeping the filter area and spray paths clear prevents pump and motor overload.
• Detergent and rinse aid use: Rinse aid improves drying and helps water sheet off dishes.
• Loading habits: Overloading blocks spray arms and forces longer, harder-running cycles.
• Drain performance: Slow draining can leave debris that increases wear on moving parts.

Maintenance checklist (best ROI)

• Run the kitchen hot water until it is hot before starting a cycle (helpful when the dishwasher is far from the water heater).
• Keep rinse aid filled and adjust the setting if drying is weak.
• Inspect and clear spray arm holes; replace damaged spray components when needed.
• Clean the tub and filter area regularly; remove labels, glass, and food debris.
• Address draining issues early; a restricted hose can shorten component life.

Common wear items vs. “long-life” components

Component area	What you’ll notice first	Typical fix
Water fill	Slow fill, poor wash	Check supply; replace inlet valve if failing
Washing circulation	Weak spray, noisy wash	Clean spray paths; service pump/motor
Draining	Standing water, odors	Clear hose/air gap; service drain pump
Door sealing	Leaks at corners	Replace door seal

Parts that often come up in longevity repairs

If performance problems start showing up, these model-matched parts are common suspects:

• Dishwasher water inlet valve 5221DD1001E
• Dishwasher drain hose AEM74333104
• Dishwasher drain pump ABQ75742501
• Dishwasher door seal 3920DD3002D

Why it matters

A dishwasher that is filling with hot water, draining freely, and spraying strongly runs shorter, more efficient cycles. That reduces heat and load on the motor, pumps, and control components, which is the simplest path to reaching the 10 to 15 year lifespan range.

For cycle options, rinse aid adjustment, and hot-water-start guidance specific to this model, use the LDTS5552D manual.
