KitchenAid KSSC42QVS03 built-in refrigerator Parts

To replace the water filter on your KitchenAid KSSC42QVS03 side-by-side refrigerator, remove the old cartridge, insert the new one fully, then push in and twist clockwise until it stops. After replacement, flush the water system and discard the first batches of ice.

Step-by-step: replace the filter cartridge

• Dispense a little water first to relieve pressure (if your model has a dispenser).
• Remove the old filter by pulling it out, or by pushing in and turning it counterclockwise (depending on the filter housing style).
• Insert the new refrigerator water filter EDR3RXD1 and seat it fully.
• Push in and twist clockwise (to the right) until it stops and feels locked.
• Reinstall the filter cap if your model uses one (a loose cap can cause leaks).
• Check for drips around the filter area for the next few minutes.

Water system prep after replacing the filter

After connecting the refrigerator to a water source or replacing the water filter, we follow the model’s water-system preparation steps to clear air and rinse the new cartridge.

• Run and discard several glasses of water to flush air from the line.
• If your ice maker is on, discard the first two full containers of ice after a filter change.
• If water sputters, keep dispensing until the flow is steady.

Quick troubleshooting if water flow is weak after a filter change

Weak flow is usually a water-pressure or restriction issue.

What you notice	Most common cause	What we do next
Slow dispenser flow	Low supply pressure	Confirm supply is in the 30 to 120 psi range
Flow drops with reverse osmosis	RO system pressure too low or RO filter clogged	Replace the RO sediment filter; allow RO tank to refill
Drips at filter area	Filter not fully seated or cap not tight	Reseat filter; check the cap fit

Why it matters

A properly installed filter helps protect the water inlet valve and dispenser from debris, improves taste and odor, and prevents air in the line that can cause sputtering, hollow ice, or slow fill.

KitchenAid built-in refrigerators like model KSSC42QVS03 do not use a dedicated ice maker “reset button.” We reset ice production by switching the ice maker OFF, then ON at the freezer’s ice maker On/Off switch and allowing the unit time to cycle and refill.

How to reset the ice maker on KSSC42QVS03

Use the ice maker On/Off switch in the freezer compartment (commonly at the top right).

• Open the freezer door.
• Move the switch to OFF (right).
• Wait 1 minute.
• Move the switch to ON (left).
• Close the door and wait for the next harvest and fill.

For the exact switch location and water-system prep steps, follow the installation guide.

What to expect after turning it back on

Startup timing is normal after an OFF/ON reset, water hookup, or filter change.

After reset	Normal expectation	Action
First ice is delayed	Up to 24 hours for first batch	Wait and keep freezer closed
Early cubes look odd	First batches can be imperfect	Discard first batches
Small/hollow cubes	Air in line or restricted flow	Flush dispenser, check filter

If it still will not make ice

These checks solve most “no ice” complaints after a reset:

• Confirm the household shutoff valve is fully open.
• Make sure the ice maker was OFF until the water line was connected.
• If you replaced the filter, flush water to clear air; see how to replace the water filter in a KitchenAid refrigerator.
• Check for a frozen fill tube (often tied to low temps or slow-seeping valve).
• Listen for a fill sound after a harvest; no fill points to water supply or a valve issue.

Why it matters

An OFF/ON reset restarts the ice maker cycle without disassembly and is the right first step after water line work or a water filter replacement.

Water leaking from your KitchenAid KSSC42QVS03 side-by-side refrigerator is usually caused by a clogged or frozen defrost drain, a loose or kinked water supply line, or a leaking water system component (filter housing, fittings, or inlet valve). Start by checking for ice or debris in the drain area and inspecting all water connections.

Quick checks that solve most leaks

• Look for water under the freezer side; that often points to a defrost drain issue.
• Check the water filter area for drips, especially after a recent filter change.
• Inspect the water supply tube behind the refrigerator for kinks or rubbing.
• Confirm the shutoff valve location allows the line to stay unkinked when the unit is pushed in (see the installation guide).
• Verify doors close fully and gaskets seal; warm air can create excess frost that later melts and leaks.

Most common leak sources (and what you will notice)

Leak location	Most likely cause	What you will see
Inside freezer, water on bottom	Defrost drain clogged or frozen	Ice sheet, then water after defrost
Under front of unit	Drain pan overflow or drain tube issue	Intermittent puddles
At filter area	Filter not seated, cap/housing leak	Drips near filter compartment
Behind unit	Supply line or fitting leak	Water trail from rear
Dispenser/ice maker area	Inlet valve or tubing seep	Slow leak, low ice production

Parts that commonly fix water leaks on this model

If you find the leak is coming from the filtration or water supply system, these model-matched parts are common solutions:

• Refrigerator water filter EDR3RXD1 if the filter is due or was installed incorrectly
• Refrigerator water filter cap (black) WP2260518B if the cap is cracked or not sealing
• Refrigerator fitting WP2300868 if a connection is seeping
• Refrigerator water inlet valve WPW10159842 if the valve weeps or won’t fully close

Why it matters

Even a small leak can lead to ice buildup, poor cooling airflow, and floor damage. Fixing the source early also helps your compressor and fans run less, improving temperature stability.
