Why Is My Water Heater Not Heating Up Despite Resetting the Button?

Resetting usually won’t fix the root cause. Common reasons a water heater still won’t heat include sediment build-up that needs flushing, incorrect temperature settings, a pilot light issue (gas units), loose connections or faulty wires, pressure valve problems, or leaks and rust that point to replacement. Our licensed, insured plumbers handle installation, repair, maintenance, and 24/7 emergencies in Glendale Heights, St. Charles, and nearby.

Quick checks:

• Verify the thermostat setting.
• Check the pilot light.
• Look for leaks, rust-colored water, or rumbling.
