If your shower feels icy or the kettle won't boil, you’re dealing with a hot water issue. Most problems come from a water heater that won’t turn on, a broken thermostat, or sediment build‑up inside the tank. The good news is many fixes are simple and you can save a call‑out fee. The bad news is some jobs need a qualified technician, especially when electricity or gas is involved.
First, check the power. A tripped breaker or blown fuse can shut the heater down instantly. Reset the breaker and try again before digging deeper. Next, look at the pilot light on a gas heater – if it’s out, follow the manufacturer’s safety steps to relight it. If the heater runs but water stays lukewarm, sediment may be coating the heating element. Flushing the tank can restore performance, but only do this if you’re comfortable with a garden hose and a drain valve.
1. Reset the heater. Many electric models have a reset button near the thermostat. Press it, wait a minute, then test the water.
2. Check the thermostat. If the setting is too low, raise it a few degrees and see if hot water improves.
3. Flush the tank. Turn off power or gas, attach a hose to the drain valve, and let the water run until it looks clear. This removes sediment that can cause overheating.
4. Inspect the anode rod. A corroded rod speeds up tank decay. Replacing it can add years to your heater’s life.
If any of these steps feel unsafe, especially working with gas lines or electricity, stop and call a professional.
