No Hot Water? 6 Things to Check Before You Call a Plumber

By Done Wright Plumbing · Updated 2026-11-05

Waking up to a cold shower is miserable. Run through these checks — some take 30 seconds.

  1. Pilot light (gas): look through the viewing window. If it is out, follow the relight instructions on the tank. If it will not stay lit, the thermocouple has failed.
  2. Breaker (electric): a tripped 30-amp double breaker is the most common cause.
  3. Thermostat: make sure nobody turned it to 'vacation'.
  4. Gas supply: is the range working? If not, the problem may be the gas line or utility.
  5. Leaks: water around the base means the tank has failed.
  6. High-limit reset (electric): press the red button behind the upper access panel.
