KitchenAid KBFS25ETSS00 bottom-mount refrigerator Parts

On a KitchenAid refrigerator like model KBFS25ETSS00, the model number is printed on the appliance’s rating label. We most often see that label inside the fresh food compartment on a side wall near the crisper drawers, or around the door opening where the door gasket seals.

Common places to check

Look for a white or silver sticker or plate that lists model and serial information:

• Inside the refrigerator section on the left or right interior wall
• On the ceiling of the fresh food compartment (near the light housing)
• Along the door jamb (the frame you see when you open the refrigerator door)
• Behind the crisper drawers or just above them on the liner wall
• On the back exterior panel near the bottom (less common, but worth a quick look)

How to find it fast

Use these steps so you do not miss the label:

• Open both refrigerator doors and scan the door frame first
• Remove the crisper drawers if they block the side walls
• Wipe condensation or smudges off the liner so the print is readable
• Take a photo of the label so you can zoom in on the model number
• Write down the full model number exactly as shown (including any trailing digits)

What the label looks like

Most KitchenAid rating labels include the same core fields.

Label field	What it’s used for
Model number	Matching the correct parts list and diagrams
Serial number	Identifying production run details
Electrical ratings	Verifying power requirements for service

Why it matters

Using the exact model number helps us match the right replacement parts for your KBFS25ETSS00, such as a door switch, ice maker, or water inlet valve. If you are troubleshooting door light or dispenser issues, the refrigerator door switch W11396033 is one example of a model-matched part you can cross-check.

The most common KitchenAid refrigerator problems (including the KitchenAid KBFS25ETSS00 bottom-mount refrigerator) are ice maker issues, cooling problems (warm refrigerator or freezer), and water leaks. In most homes, these symptoms trace back to airflow restrictions, dirty condenser components, or water system parts that are partially clogged or failing.

Most common symptoms we see

• Ice maker not making ice or making small/hollow cubes
• Refrigerator section too warm while freezer seems OK
• Freezer too warm or frost buildup on the back wall
• Water leaking under the refrigerator or inside the fresh food section
• Unusual noises (fan noise, rattling, buzzing)

Quick checks that solve many “common problems”

1. Confirm temperatures: set refrigerator to about 37°F and freezer to about 0°F.
2. Check door closing and sealing: a poor seal causes temperature swings and frost.
3. Clean airflow paths: do not block vents with food packages.
4. Inspect the condenser area: dust buildup can cause warm temps and longer run times.
5. For ice and water issues: verify the household shutoff valve is fully open and the supply line is not kinked.

Likely causes and the parts that often fix them

Symptom	Common cause	Part on this model that may apply
Ice maker not working	Ice maker module failure or water supply problem	Whirlpool refrigerator ice maker (D7824706Q) D7824706Q
No water to ice maker	Water inlet valve not opening fully	Refrigerator water inlet valve assembly WP67006531
Warm temps, long run time	Dirty or restricted condenser system	Refrigerator condenser fan blade W10156818 or refrigerator condenser coil WP67006131
Frost buildup, poor cooling	Defrost system problem	Refrigerator defrost heater WP67002493
Puddles under fridge	Drain system issue or water line connection leak	Refrigerator water supply tube union, 5/16 x 5/16-in WP2300868

Why it matters

Ice maker failures, leaks, and temperature fluctuations can quickly lead to spoiled food, ice clumps, and compressor strain. Catching the root cause early usually prevents bigger repairs and keeps your KitchenAid refrigerator running efficiently.

To replace the water filter in your KitchenAid KBFS25ETSS00 bottom-mount refrigerator, locate the filter compartment (typically inside the fresh food section), unlock the filter, then twist and pull the old filter out. Install the new filter by pushing it in and twisting until it locks.

Step-by-step: replacing the water filter

• Dispense a little water first (if your model has a dispenser) to relieve pressure.
• Open the filter compartment door or cover.
• Turn the old filter to the unlock position (usually a quarter-turn to a half-turn).
• Pull the filter straight out; keep a towel handy for a few drips.
• Insert the new filter fully, then twist to the lock position.
• Close the compartment door or cover.

After you install the new filter

Most refrigerators need a quick flush to clear air and carbon fines.

• Run and discard several glasses of water.
• If the dispenser sputters, keep dispensing until the flow is steady.
• Dump the first full bin of ice (if you have an ice maker) after a filter change.

Quick checklist

What you notice	What it usually means	What to do
Filter will not turn/lock	Not fully seated or misaligned	Reinsert and twist firmly until it stops
Slow water flow	Air in line or filter not seated	Flush water; reinstall filter if needed
Leaking at filter area	O-ring not sealing	Remove filter, check for debris, reinstall

Why it matters

A properly installed refrigerator water filter helps protect your water system from sediment buildup and keeps water flow and ice production consistent.

Water under your KitchenAid KBFS25ETSS00 bottom-mount refrigerator is most often caused by a clogged or frozen defrost drain that makes defrost water overflow and run to the floor. The next most common causes are a leaking water line connection or a seeping inlet valve.

Quick checks we recommend

• Unplug the refrigerator before removing panels or working near wiring.
• Check the freezer floor for a sheet of ice or standing water (points to a defrost drain issue).
• Look at the drain pan area for cracks or a pan that is out of position.
• Inspect the water line and fittings behind the unit for drips (especially if the ice maker is connected).
• Confirm doors close fully; warm air leaks increase frost and can overwhelm the drain.

Most common cause: clogged or frozen defrost drain

During defrost, meltwater should flow through the drain hole and tube into the drain pan. If the drain is blocked by ice or debris, water backs up into the freezer and eventually leaks out.

What to do

• Remove freezer items and locate water or ice at the bottom.
• Melt ice around the drain area using warm water.
• Flush the drain with warm water until you hear or see water reaching the drain pan.

Symptom	Most likely cause	Best next step
Water under fridge plus ice on freezer floor	Frozen/clogged defrost drain	Thaw and flush the drain
Leak happens when ice maker fills	Water line fitting or valve leak	Inspect tubing and valve area
Water near front corners	Door not sealing well	Inspect gasket and alignment

Water supply leaks to rule out

If you see dripping at a connector or fitting, a damaged union can be the source; the refrigerator water supply tube union, 5/16 x 5/16-in WP2300868 is a common fix. If the valve body is wet or seeping, the refrigerator water inlet valve assembly WP67006531 is the part to replace.

Why it matters

Stopping the leak prevents floor damage and helps avoid heavy frost buildup that can reduce cooling performance.
