This decoder supports the documented Bradford White two-letter date prefix and GE’s standard two-letter, six-digit, final-letter format. It reports possible manufacturing dates, not installation dates. Older or other formats require manufacturer confirmation.
Warranty and remaining life
Warranty status: not determined here. Use the manufacturer’s lookup and original purchase or installation documents. Coverage may depend on the product, registration, ownership, location and exclusions. A serial date alone is not a warranty decision.
Remaining service life cannot be calculated from a serial number. Condition, maintenance, water quality, installation and use matter. Arrange assessment for leaks, unusual operation or safety warnings regardless of age. Do not keep unsafe equipment running to reach an estimated replacement age.
