We purchased a Whirlpool water heater from Lowe's on 1/6/2017. It is model ES50R10-55. It has a 10 manufacture warranty. It is leaking and needs to be replaced. I contacted Lowe's and they told me it was Whirlpools responsibility. I tried contacting Whirlpool by phone and by website and can not get any help. We need to get the water heater replaced asap. How do we get warranty assistance?
