Googled Samsung parts booklet for my particular washing machine. Ordered from you guys. Arrived very quickly. For an 80 yr. old woman, I'm proud of myself. Other than standing on a short stool to get far enough into the machine to push on the cap and having to get my husband as my arms were not long enough to push the cap home, his were. Oh, in order to get the complete model number I took my cell phone and reversed the camera screen to take picture of back of machine as I wasn't about to move the machine to get the number.
