Bosch Dishwasher Junction Box Kit SMZPCJB1UC / Power Cord with Junction Box 11031987

Dishwasher junction box kit containing a pre-attached power cord, junction box, and strain relief. It provides a secure electrical connection for Bosch-family dishwashers, including hardwired installations, and can be used in place of a three-prong power cord. Bosch states it is not for 100 Series or Ascenta dishwashers manufactured before January 2020.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Your Bosch dishwasher is completely dead — no display, no lights, no response
• ✔ The circuit breaker is confirmed on and the supply wire has power at the wall
• ✔ The dishwasher is a hardwired installation (not plug-in) or the existing cord is damaged
• ✔ ONLY problem is no power reaching the dishwasher — no error codes or partial function

🔧 Common Symptoms

• Dishwasher completely dead — no display, no lights, no sounds at all
• New Bosch dishwasher installation — power cord not included in the box
• Existing power cord visibly damaged, burned, or melted at the junction box
• Dishwasher tripping the breaker immediately on startup
• Intermittent power loss — dishwasher cuts out randomly mid-cycle
• Junction box wiring loose, corroded, or improperly terminated

✔ If these symptoms match, this is the most likely missing or failed component in the system.

✔ In most cases, installing this power cord with junction box kit restores full dishwasher operation immediately.

⚙️ Installation

Skill Level: Moderate — 20–30 minutes. Disconnect power at the breaker before servicing — this is a live electrical component. Pull the dishwasher out from the cabinet to access the junction box mounting location on the underside or rear of the unit. Connect the supply wires to the junction box terminals (black to black, white to white, green/bare to ground), secure the strain relief clamp, and mount the junction box. Restore power and test operation before pushing the dishwasher back into the cabinet.
