Beko Dishwasher DFS28123x Docking Port Seal (Repair Kit for KL62123R22)This 3D model is a specialized repair solution for the upper spray arm manifold in Beko dishwashers (part no. KL62123R22). It fixes a common failure point that the manufacturer considers "non-repairable."

The Backstory: Proven PerformanceI created this model out of necessity. Although the original factory part is relatively inexpensive, I was faced with a nearly 3-week lead time for delivery. Instead of waiting, I designed and printed this TPU replacement.

The results exceeded expectations: I used this 3D-printed seal successfully for nearly 3 months with zero issues. In fact, it worked so reliably that I completely forgot I had even ordered the original part until it had been sitting in my drawer for weeks.

The Problem: Degradation of Integrated SealsThe original docking port on the back wall of the dishwasher uses an integrated purple rubber seal bonded to a grey plastic housing.

Failure: Over time, heat and chemicals cause this purple rubber to flatten, wear out, or disappear entirely.

Consequence: When the basket is pushed in, the connection is no longer watertight. Water leaks at the back wall, significantly dropping the pressure in the spray arm and leaving dishes dirty.

OEM Restriction: Beko does not sell this seal separately. They expect you to replace the entire manifold.

The Solution: TPU InnovationBy using TPU, we can restore the seal that the factory doesn't want you to fix.

Material: TPU’s elasticity is mandatory here. It provides the necessary "give" to seal against the spray arm pipe and allows for a press-fit installation that a rigid plastic couldn't achieve.

Durability: TPU is highly resistant to the friction and "docking impact" of the basket movement.

Installation Guide (Critical Step):To achieve a perfect seal, you must prepare the socket:

Clean the Socket: Use a small manual milling tool or a rotary tool (like a Dremel) to carefully grind away and remove the remains of the old, degraded purple rubber.

Surface Prep: Ensure the inside of the grey plastic ring is smooth and free of debris.

Press Fit: Insert the TPU print into the cleaned socket. The fit is designed to be snug so that water pressure doesn't dislodge it.

PRINT SETTINGS (Important!):

Orientation: Print WITHOUT supports.

Positioning: Place the model on the build plate with the seal lips (flaps) facing UP. This is crucial for maintaining the correct geometry and sealing performance.

Material: TPU (recommended Shore Hardness approx. 40D ~90A or 85A for better flexibility).

Infill: 15% (I found this lower infill provides better flexibility for a tighter seal).

Wall Loops: 2.

Layer Height: 0.20 mm.By printing this part, you save money, avoid unnecessary plastic waste, and get your dishwasher back to 100% efficiency immediately without waiting for shipping.
