Refrigerator Not Filtering? Water Filter Cap 00622349 – Fix Leaks & Bypass Fast
A missing, cracked, or broken water filter cap allows unfiltered water to bypass the filter entirely and causes leaks inside your refrigerator compartment. In most Bosch refrigerators, this is caused by a failed water filter cap. When it fails, water bypasses the filter cartridge, pools inside the fridge, and the filter housing cannot seal properly. ⚡ Common failure point in Bosch-built refrigerators. Part 00622349 is the genuine OEM replacement that restores a watertight seal and ensures all water flows through the filter as designed.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Your refrigerator powers on and runs normally
- ✔ Cooling and ice maker functions work correctly
- ✔ Your home water supply is confirmed OK
- ✔ The water dispenser line is intact and unkinked
- ✔ ONLY problem is a missing, cracked, broken, or leaking filter cap

📦 Part Details
- Part Number: 00622349
- Type: Refrigerator Water Filter Cap – plastic housing cap for filter cartridge bay
- Replaces: OEM direct-fit water filter cap assembly — supersedes 622349 (no modification required)
- Brands: Bosch
While the filter housing is exposed, inspect the water filter cartridge itself for age or damage — Bosch recommends replacing the filter every 6 months. Replacing both the cap and the filter at the same time saves a second service call and ensures fully filtered water from day one.
⚙️ Installation
Skill Level: EASY — 2–5 minutes. Unplug the refrigerator or shut off the water supply before beginning. Remove the old or damaged cap from the filter housing, align the new cap 00622349, and press or twist firmly into place until it seats and seals. No tools required. Confirm there are no leaks before returning the refrigerator to service.

💡 Pro Tip
If the cap cracked or broke during a routine filter change, the cartridge itself may be due for replacement anyway. Ordering a fresh Bosch-compatible filter cartridge alongside this cap means you only open the housing once — saving time and avoiding a second water shut-off. Check your filter's install date before you order.
