A water heater that stops working is more than an inconvenience — especially in a Springfield MO winter. Whether you're getting cold water, discolored water, or no water at all, here's how to diagnose the problem and decide whether to repair or replace your unit.
Common Reasons Your Water Heater Stopped Working
No hot water at all:
Gas: pilot may be out — relight per label instructions. Won't stay lit: thermocouple failure.
Electric: check the breaker — reset and wait an hour.
Lukewarm water: Thermostat too low (set 120–140°F) or heating element failing.
Rusty or discolored water: Tank corroding inside — replace unit.
Popping or rumbling: Sediment buildup — flush the tank.
Repair vs Replace: How to Decide
Repair if: Under 8 years old, single component failed, no corrosion, no leaks.
Replace if: 10+ years old, rust or corrosion visible, tank leaking, repeated repairs, or repair cost exceeds 50% of replacement.
