WV60M9900AV Upper Washer 1dC4: Inspect the Latch Button

Fixlume editorialSource check: October 16, 2026Samsung · washers
The short answer

On FlexWash, Samsung identifies a missing rubber button beside the upper washer latch as a cause of 1dC4. Inspect that visible item before assuming the entire lock assembly needs replacement.

Models covered

WV60M9900AV/A5; match the complete model suffix and the cited manual/control panel before following a sequence.

Before you begin
Wait for motion to stop and the door or lid to unlock. Water may be hot. Isolate power and follow the exact manual before any user filter maintenance. Never open a filter against a full drum, force a lock or bypass an interlock.

Compare the behavior

Match the documented control, cycle or feature before interpreting the result. The comparison below keeps normal model behavior separate from an unresolved fault.

Model-specific checks

Confirm which washer is complaining

FlexWash contains upper and lower washing sections. Photograph the panel and the complete code, including its leading 1. That prefix and the affected section matter; a lower-drum problem should not be sent down an upper-latch-button path simply because both doors are locked.

Use observation before disassembly

With the washer stopped and safely accessible, look beside the upper latch for the rubber button. Do not poke tools into the latch or substitute tape, a magnet or another object. Samsung says replacement of the missing button resolves that particular condition; it does not say every 1dC4 proves the button is missing.

If the button is present

A visible button with a continuing error, a broken handle or a lid that cannot safely release needs Samsung service. Parts catalogs establish model compatibility, not a diagnosis. Match the full suffix and revision before ordering any owner-replaceable item, and use Samsung instructions rather than improvising access.

What to record next

This is a narrow, manufacturer-documented exception to immediately suspecting an expensive door assembly. It is not permission to bypass the latch or force a stuck lid.

When to stop and get help

Only carry out maintenance permitted in your model’s manual. For service, note the full model number and suffix, displayed code, selected cycle and what happened during the checks. Leave internal wiring, gas components, pumps and safety devices to a qualified professional. A symptom alone does not identify a failed part.
