The plumber was called out because our hot water heater was not working. Before the plumber came out he was very thorough and asked us if we had a fuse box and extra fuses. We said yes. He tested the hot water heater and some power was going to it. He checked the special AA battery sized fuses and found a blown fuse. Thankfully we had two extra fuses and he replaced the two old ones for the new ones. We did not need a replacement hot water heater which was a great relief.
