Water Heater Not Working? Fast Fixes & When to Call a Pro
If you’re standing under a cold shower, the first thing you’ll wonder is why your water heater stopped working. The good news is many problems are easy to spot and fix yourself. The bad news is some issues need a qualified technician, especially when safety is involved. Below are the most common reasons a water heater won’t heat and what you can do right now.
Quick Checks You Can Do Now
1. Power or gas supply – For electric heaters, make sure the circuit breaker hasn’t tripped. Flip it off and on again. For gas units, confirm the gas valve is open. If you smell gas, step outside and call a professional immediately.
2. Reset button – Most modern heaters have a reset button near the thermostat. Press it once; if the unit fires up, the problem was a temporary overload.
3. Thermostat setting – It’s easy to set the thermostat too low by accident. Set it to 120‑130°F (49‑54°C) and see if the water warms up after an hour.
4. Pilot light – Older gas heaters rely on a pilot flame. If it’s out, follow the manufacturer’s instructions to relight it. If it won’t stay lit, the thermocouple may be faulty.
5. Drain valve leak – A leaking valve can let hot water escape, making the tank feel cold. Tighten the valve or replace the washer if you’re comfortable doing so.
6. Sediment build‑up – Over time minerals settle at the bottom of the tank and insulate the heating element. Flushing the tank once a year can restore performance. Turn off power or gas, attach a garden hose to the drain valve, and let the water run until it’s clear.
When to Call a Professional
If the quick checks don’t bring hot water back, it’s time to get help. Here are signs you need a pro:
• The unit makes strange noises – banging or popping usually means severe sediment or a failing tank.
• Water is rust‑colored or has a metallic taste – this hints at tank corrosion.
• The heater leaks from the top or bottom – a leaking tank can’t be repaired safely; replacement is the usual solution.
• You’re dealing with a gas line or electrical components you’re not comfortable touching – safety first.
