Make sure you have power going to elements from thermostats. check lines going to elements.
Luke warm water is the result of an element gone bad most of the time. One at th etop gone will cause you to get just luke warm water and one at the bottom gone will give you real hot and then cold.
The elements are not to exspensive so if it has two you might as well replace both of them. If you just put 1 new one in it will work the old one till it goes.
Cut power off and cut water off to water heater and drain heater, open hot side on any faucet to help it drain. once drained remove element they have a tube type socket at hardware stores for the removal of it.
Put elements in and fill water heater till all air is out of lines before turning power back on. make sure water is flowing out of all faucets before turning power onto water heater.
The reason being is the elements has to be in water not open air in tank or it will blow new ones.
