LG Dishwasher Leaking or Won't Drain? Pump Casing Assembly AGM30016301 – Fix OE/LE Error Fast

If your LG dishwasher is leaking from the sump area, throwing OE or LE error codes, or failing to drain completely, a cracked or failed pump casing is the most common cause. In most LG-built dishwashers, the pump casing seals the circulation and drain pump assembly — when it cracks or warps, water escapes the sump, pressure drops, and the machine faults mid-cycle. ⚡ Common failure point in LG LDP, LDT, LDTS, LSDTS, and LUDP series dishwashers. Part AGM30016301 is the genuine OEM replacement that restores a watertight seal and full pump performance — direct fit, no modification required.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Dishwasher powers on and attempts to run a cycle
• ✔ Water fills correctly — inlet valve and supply confirmed OK
• ✔ Drain hose and filter are clear of blockages
• ✔ Control board shows OE, LE, or FE error — or visible leak from sump area
• ✔ ONLY problem is leaking, poor drainage, or pump-related error codes

🔧 Common Symptoms

• OE error code — drain fault, most common customer search
• LE error code — motor or pump overload fault
• FE error code — overfill caused by pressure loss at casing
• Water leaking from under the dishwasher — sump seal failure
• Dishwasher stops mid-cycle — pump pressure loss triggers safety shutoff
• Poor cleaning performance — reduced circulation pressure from cracked casing
• Excessive noise from pump area — air ingestion through casing crack

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing this pump casing assembly restores normal operation immediately.

⚙️ Installation

Skill Level: ADVANCED — 60–90 min DIY / 45–60 min Professional. Disconnect power and water supply before beginning. Lay the dishwasher on its back to access the sump assembly from below; disconnect the wiring harness, drain hose, and circulation hose before unclipping the casing. Ensure all O-rings and seals are fully seated during reassembly — any gap at the casing joint will result in a repeat leak.
