A:AnswerNo they are not necessary. However they do bring up the washer and dryer so you don't have to bend over as much when loading or unloading. We didn't purchase them because we have cabinets above them and we fold clothes on top of them. With the pedestals we wouldn't have enough room to fold clothes on top.
A:AnswerThat is definitely not right! You have probably checked the obvious (like is the cycle complete, etc) so, were I you, I would get on the phone to Best Buy and get them out to your house ASAP and fix/replace it!
A:AnswerThe ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Capacity High Efficiency Front Load Washer with Steam Technology in Graphite Steel, Model # WM3770HWA, has 3/4" connectors on the hoses for the hot and cold water inlet valves that have to be connected a water supply. The water supply pressure must be between 20 psi and 120 psi {138-827 kPA}. A pressure reducing valve must be installed if the water supply pressure is more than 120 psi, so you will need to check on the specifications for your tankless water heater and check that it has the appropriate connections...^IFV
