Kenmore 153331572 water heater Parts

For your Kenmore water heater model 153331572, the year is identified by reading the serial number on the rating/data plate and decoding its date format. Because serial formats vary by manufacturer and production run, we use the date-code guidance in the 153331572 owner's manual to confirm where to find the plate and what information to record.

Where to find the serial number (and what to write down)

Look on the water heater’s data plate (usually on the tank’s exterior). Record these items before you decode anything:

• Model number: 153331572
• Serial number (copy it exactly, including letters)
• Product number (if listed)
• Gas type (natural gas or LP)
• Input rating (BTU) from the data plate

Common serial number date-code patterns (what the first digits often mean)

Many water heater manufacturers encode the build date near the start of the serial number. These are the most common patterns you will see:

• YYWW: first 2 digits = year, next 2 digits = week (example: 1220 = week 20 of 2012)
• MMYY: first 2 digits = month, next 2 digits = year (example: 0915 = September 2015)
• Letter + numbers: a letter may represent the month, followed by a year code (varies by maker)

Quick decode table (examples)

Serial starts with	Typical meaning	Example result
YYWW	Year + week number	1220 = week 20 of 2012
MMYY	Month + year	0915 = September 2015
Letter code	Month/year encoded	Use the maker’s code chart

Why it matters

Knowing the manufacture year helps you plan maintenance and parts replacement. For example, anode rods often need periodic replacement to help protect the tank from corrosion; for this model, a common maintenance part is the water heater anode rod 100108660.

Your Kenmore water heater’s model number is printed on the rating plate (data label) attached to the tank; for this unit, you’re looking for MODEL NO. 153.331572. Use that exact model number when ordering parts, checking specifications, or following troubleshooting steps in the owner's manual.

Where to find the model number on the heater

Look for the rating plate label on the outside of the tank (often on the side near the gas control area). The label typically includes both the model number and serial number.

• Find the label that says MODEL NO.
• Confirm it reads 153.331572 (50-gallon tall, natural gas)
• Write down the serial number too (helpful for age and production details)
• Keep the label intact; it’s used for service and parts identification
• Match the model number exactly when searching for parts like a thermocouple or pilot assembly

What information matters (and what usually doesn’t)

For parts lookup and repair, the model number is the key identifier. Other numbers on the label can be useful, but they are not usually needed to find common replacement parts.

Label item	What it’s used for	When you need it
Model number (153.331572)	Correct parts list and diagrams	Always
Serial number	Manufacturing details	Service calls, warranty questions
Input BTU / gas type	Setup and safety checks	Installation, gas conversion questions
Tank capacity	Sizing and replacement planning	Comparing heaters

Why it matters

Kenmore model numbers can look similar (for example, 153.331472 vs 153.331572), but they can use different parts. Using the exact model number helps ensure you get the right items, such as the thermocouple 100108267 or the correct pilot components.

Most Kenmore tank-style water heaters typically last 8 to 12 years under normal residential use. For Kenmore model 153331572, regular maintenance (especially corrosion protection and safe venting) helps you reach the upper end of that range; see the 153331572 owner's manual for model-specific care and safety details.

Typical lifespan and what affects it

A water heater’s service life depends heavily on water quality, usage, and maintenance.

• Water hardness and sediment: more buildup can shorten tank life
• Anode rod condition: a depleted anode accelerates tank corrosion
• Temperature setting: higher settings increase stress and scale
• Venting and combustion air (gas models): poor draft can cause performance and safety issues
• Leak history: recurring seepage at fittings or the tank base often signals end-of-life

Maintenance that extends life

These are the most effective, practical steps for a Kenmore gas water heater.

• Flush a few gallons from the tank periodically to reduce sediment
• Inspect and replace the anode rod when significantly worn
• Keep the burner area clean and the burner access door properly installed
• Confirm the vent draft hood is secure and the venting is unobstructed
• Follow the lighting and shutdown steps exactly as shown in the manual

Helpful parts for longevity (when symptoms point to them)

What you’re addressing	Common sign	Example part for model 153331572
Tank corrosion protection	Rotten-egg odor, rusty water, frequent leaks	Water heater anode rod 100108660
Pilot reliability	Pilot will not stay lit	Thermocouple 100108267
Safe pressure relief	Dripping from relief discharge pipe	Wheelers water heater temperature and pressure relief valve 100108455

Why it matters

Once a tank begins to corrode internally, repairs rarely restore long-term reliability. Staying ahead of sediment and anode wear helps prevent leaks, improves heating efficiency, and reduces nuisance pilot and burner problems.
