DIY water heater repair

Water heaters are often forgotten until there's no hot water or the water gets cold halfway through a shower. If your water heater doesn't heat quickly enough, doesn't heat at all or your hot water smells like rotten eggs, Sears PartsDirect's troubleshooting guidance can help you narrow down and fix the problem.

When the hot water disappears, follow the steps in our no hot water video to figure out what's wrong. If your water is too hot, watch our water too hot video to figure out what the cause might be. Both videos will point you toward what part to replace and our DIY repair guides will walk you through the repair step by step

If you see an error code, look it up on our water heater error code charts and then follow the steps to find out what part to replace. To find out how to drain the tank on your electric water heater or get answers to common questions, check out our articles and videos. To find the owner’s manual or a complete list of replacement parts for your water heater, search for your model number.
