GE Washer Not Draining: Troubleshooting Guide

GE UltraFresh front-load washers are popular for their features, but technicians frequently encounter drain pump failures related to main control board issues. This guide provides a detailed approach to diagnosing and resolving this “GE washer not draining” problem, applicable to a range of GE washer models, including GFW510SCN, GFW510SCV, GFW550SPN, GFW550SPR, GFW550SSN, GFW650SPN, GFW650SSN, GFW655SPV, GFW655SSV, GFW850SPN, GFW850SSN, PFW870SPV, PFW870SSV, PFW950SPT, and PFW955SPW. This information is crucial for any technician working on GE UltraFresh washers.

A common cause of “GE washer not draining” is a failure in the main control board’s drain pump circuit, preventing the drain pump from receiving power. In some instances, the drain pump is also damaged by the electrical fault.

To accurately diagnose GE washer drain problems, follow these steps:

1. Initial Checks (Essential for any “GE washer not draining” call):

• Inspect the GE washer drain hose for kinks, clogs, or obstructions
• Ensure the drain filter is clean and correctly installed
• Verify the hose installation and standpipe height comply with manufacturer specifications

2. Drain Pump Voltage Test:

• Use a multimeter to check for voltage at the drain pump connector while the washer is attempting to drainIf there is no voltage, the main control board is likely the problem

3. Main Control Board Inspection:

• Carefully examine the GE washer main control board for visible signs of damage: Burnt components, especially the Q553 transistor; Discolored areas or burn marks; Damaged traces
• Note: As seen in some cases, a burnt transistor on the board is a strong indicator of this issue

4. Drain Pump Resistance Test:

• Measure the resistance of the drain pump motor
• Compare the reading to the specification in the service manual (typically around 19.5 ohms +/- 10%)
• An open or short circuit indicates a faulty drain pump

In GE washers, the main control board and drain pump are often interdependent in failure scenarios. A malfunctioning main board can damage the drain pump, and a failing pump can overload and damage the board. To minimize callbacks and ensure a reliable “GE washer repair,” replacing both components is generally recommended.

Safety Precautions: Always disconnect the GE washer from the power source before starting any repair.

Access:

• Refer to the specific GE washer service manual to access the main control board and drain pump

Main Control Board Replacement:

• Carefully disconnect the old main control board’s wire harnesses, noting their positions
• Reconnect all harnesses securely to the new GE washer main control board

Drain Pump Replacement:

• Disconnect the old drain pump’s electrical connector and hoses
• Install the new drain pump, ensuring all connections are tight and correct

Reassembly and Testing:

• Reassemble the washer
• Run a test cycle to confirm proper drain function and inspect for leaks

• Use Genuine GE Parts: Always use genuine GE replacement parts to ensure compatibility, performance, and longevity
• Consult Service Manuals: Refer to the official GE service manuals (e.g., “31-9327 Rev. 2 UltraFresh Front Load Washer Service Guide DRAFT.pdf” and the mini manual) for accurate model-specific instructions and diagrams
• Safety First: Prioritize safety by adhering to all safety guidelines, including electrical safety practices and lockout/tagout procedures
• Technical Bulletins: Stay updated on any GE technical service bulletins (TSBs) related to drain pump or main board issues in GE washers
