LG Dishwasher Not Draining — Drain Pump Repair in Park Hill, Denver

Pre-Diagnosed Before We Arrived

During the initial phone conversation, we asked the homeowner about the symptoms they were experiencing. Based on the dishwasher not draining and the error code being displayed, we suspected a problem with the drain pump assembly. That information allowed us to bring the likely replacement part with us to the appointment — giving us the opportunity to complete the repair in a single visit if the diagnosis was confirmed.

Providing detailed symptoms and error codes when scheduling can sometimes help us narrow down the likely problem before we arrive. When possible, we'll bring the likely parts with us so the appliance can be diagnosed and repaired during the same appointment.

Diagnosing the LG Dishwasher

Cody arrived at the Park Hill home and inspected the dishwasher. Testing confirmed that the drainage problem was caused by a failed drain pump/case assembly. The drain pump is responsible for pumping water out of the dishwasher tub at the end of each cycle. When it fails, water remains standing in the bottom of the tub and the dishwasher may display a drain error code.

Because we had already brought the replacement part with us, Cody was able to begin the repair immediately after confirming the diagnosis.

LG Drain Pump / Case Assembly Replacement

Cody accessed the pump assembly underneath the dishwasher and removed the failed component. We installed a new LG case assembly, part #ABQ73503004, and properly secured the hoses and connections before reassembling the dishwasher.

Once the repair was complete, Cody ran the dishwasher through a full test cycle to verify the results:

• The new drain pump was operating properly.
• The dishwasher was draining completely at the end of the cycle.
• The unit was cycling normally through all stages.
• All hose connections and fittings remained dry with no leaks.

Everything tested properly, and the dishwasher was back in operation. The entire repair was completed in one visit.

Why Is My LG Dishwasher Not Draining?

A dishwasher that won't drain can leave standing water in the bottom of the tub and may trigger an error code on the display. Common causes include:

• A failed drain pump or pump/case assembly.
• A clogged drain filter or sump area.
• A kinked or blocked drain hose.
• A failed drain solenoid or check valve.
• A control board issue preventing the drain cycle from initiating.

In this Park Hill repair, the drain pump itself had failed. Proper diagnosis is important before replacing parts, since the same symptom can have different root causes depending on the model and situation.
