• Extinguished Pilot Light: On traditional gas units, a draft or faulty thermocouple can knock out the pilot flame.
• Tripped Circuit Breaker: Electric water heaters rely on dedicated double-pole breakers that can trip under power surges.
• Sediment Accumulation: San Jose's tap water contains moderate mineral hardness, leading to mineral crust at the bottom of the tank that insulates water from heating elements.
• Failed Heating Elements or Thermostat: Over time, electrical components burn out and stop transferring heat.
• Gas Control Valve Malfunction: Faulty valves prevent fuel from reaching the burner assembly.
When basic checks fail to restore your system, dial +1 (380) 247-0397 to schedule a comprehensive system diagnostic.
Before calling for emergency service, follow this fast diagnostic sequence to isolate simple issues.
For electric models, check your main breaker panel. Reset any tripped switches. For gas models, confirm the gas shut-off valve is open and check if other gas appliances in your home are working properly.
