Like so many others here, I ordered a flowmeter. Ordered it just before midnight on a Thursday and it was delivered Saturday morning - during the Christmas rush! Loosened 3 nuts on top rear of the washer, popped off only the top - not the entire back - replaced the flowmeter in about 5 minutes. Washer again works flawlessly. Part was so inexpensive and so easy to replace that it was well worth trying even if it hadn't worked.
