State water heater: frequent clicking or cycling on and off with small temperature changes.

Safety: Turn off power (electric) or set gas control to pilot before adjusting controls.

• Verify thermostat placement: Ensure the thermostat or sensor is properly mounted against the tank in the designated well.
• Adjust setting: Slightly widen the temperature differential if the control allows (installer menu on some State models).
• Insulate piping: Insulate hot and cold pipes near the heater to reduce rapid temperature swings at the sensor.
