What’s Wrong With Your Water Heater? Symptom-to-Cause Guide
No hot water at all: Gas unit — pilot light out or thermocouple failed ($150–$250 repair). Electric unit — element failed or breaker tripped ($200–$400 repair). Tankless — write down the error code and call; don’t keep cycling power.
Lukewarm or inconsistent temperature: Sediment buildup on the tank bottom. In Plano’s hard water, this develops faster than in most markets.
Rust-colored hot water: Drain three buckets in sequence. If the third is still rust-colored, the tank is corroding internally. Plan replacement.
Water around the base of the tank: If the tank itself is wet at the bottom — the tank has failed. Shut off the cold water supply valve and the gas or breaker. Call immediately.
Popping, rumbling sounds: Sediment layer on the tank bottom. Annual flushing prevents this.
