What People Are Saying

Rated 5 out of 5 by from Great sales, service and product! Bought new washer (do not want to list product due to factory defect) and I want to thank Eden, Jerry and the entire staff at Mtn. Home, Ar. Sears store for your superior sales and service. After purchasing a new washing machine that leaked, Eden immediately called repair and then just as fast replaced it with a new identical washing machine, which unfortunately leaked in the exact same spot! Eden stepped up to the plate again and offered a full refund and I upgraded to a LG Turbowash 4.5 Cu. Ft. Model WM3770HVA which is a fantastic machine. I have 2 dogs and it cleaned their mess and left the blankets smelling the freshest I have ever experienced! I also want to mention they delivered and set these up all three times not charging me any extra fees what so ever! Jerry the gentleman that did all three deliveries & setups, was very knowledgeable and a lot of patience because the first washer he deliver, they had to construct clamps to fit my old cabinet drawers. He went above and beyond what was required of him! Again I cannot thank the people at the Sears Hometown Store in Mountain Home, AR for their fantastic sales, service and products! They really do stand behind their products just like in the good ole days!!

Rated 5 out of 5 by from I love my new machine I've had this machine for a month now and it's great. My old machine sounded like an airplane was taking off and this one can hardly be heard at all! My husband even commented that the laundry looks much cleaner. The wider door opening makes a huge difference. My laundry gets done so much faster because each load has a shorter run time and it holds so much more laundry per load.

I'm unable to remove the soap dispenser by just pressing down on the tab and pulling out. Is there some other release function I am not doing? The installer delivered it today, and I asked him to show me how to remove it. He tried, but it wouldn't budge.

Asked by: Mikesgirl
Hello, please see the included link for tips and information about the dispenser. ^AC
