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:
For gas heaters — the pilot light may have gone out. Relight it following the label instructions on the unit. If it won't stay lit, the thermocouple likely needs replacing.
For electric heaters — check your breaker box. A tripped breaker is the most common cause. Reset it and wait an hour.
Water is lukewarm, not hot:
Your thermostat may be set too low (should be 120–140°F) or a heating element may be failing.
Water is rusty or discolored:
This usually means your tank is corroding from the inside — a sign the unit needs replacement, not repair.
Popping or rumbling noises:
Sediment buildup on the tank floor causes these sounds. Flushing the tank may resolve it, but heavy buildup can permanently damage the unit.
Repair vs Replace: How to Decide
Repair if:
•The unit is less than 8 years old
•The problem is a single component (thermostat, element, thermocouple)
•There's no corrosion or rust
•The tank isn't leaking
Replace if:
•The unit is 10+ years old
•You see rust or corrosion
•The tank is leaking
•You've already repaired it multiple times
•Repair cost exceeds 50% of replacement cost
Most water heaters in Springfield MO last 8–12 years. If yours is approaching that age, replacement is usually the smarter investment.
