I have a Landa hot water unit. Sometimes the unit will not start-I turn the key and nothing, not even a click. We get it started by using jumping cables. I thought it may be a dead battery; however, I had it tested and it was good. The battery and my unit are only 4 months old. Any suggestions as to the cause of the problem? Thanks!
