Bosch 233-45653-05 Pilot Assembly Water Heater

Product Description

The BOSCH 233-45653-05 is a pilot assembly designed for use in Bradford White water heaters. The pilot assembly serves as the ignition source for the main burner, generating a small standing flame that proves burner operation to the gas valve and thermocouple circuit. Licensed plumbers and gas service technicians typically handle this replacement. It is an OEM-style component intended to restore proper ignition function when the original pilot fails to light, hold flame, or generate adequate millivolt output to the gas control valve.

This pilot assembly is suited for residential gas water heater service where the original ignition system has degraded or failed entirely. It is commonly installed during routine service calls when a technician diagnoses a no-hot-water complaint traced to a faulty pilot, thermocouple, or pilot orifice. The part is manufactured for use in Bradford White gas water heater applications and carries the original manufacturer part number on the assembly for straightforward identification during service.
