Zodiac – Electrical box Z400 MD4/MD5 – R0811100

The Zodiac R0811100 is a genuine OEM replacement electrical box designed specifically for the Zodiac Z400 robotic pool cleaner in its MD4 and MD5 variants. The electrical box is the central control housing of the robotic cleaner, enclosing the electronic circuitry responsible for managing motor operation, directional control, and the overall drive logic of the robot. When the original electrical box becomes faulty due to water ingress, electrical failure, or component wear, replacing it with this genuine part restores full operational capability without the need to replace the entire cleaner unit.

This replacement box is engineered to meet the same tolerances and specifications as the factory-fitted component. It is designed to integrate directly into the Z400 MD4 and MD5 chassis without modification, ensuring a precise and reliable fit. Sourcing an OEM part rather than a generic alternative ensures compatibility with the existing wiring harness, motor connectors, and housing clips inside the robot.

Technical characteristics and compatibility

The R0811100 electrical box is compatible exclusively with the Zodiac Z400 robotic cleaner configured as MD4 or MD5 drive models. It is not interchangeable with the MD7 variant, which uses a different electrical box (R0811200). This distinction is important when ordering: always verify your Z400 model designation before purchasing. The electrical box contains the logic board and terminal connections that coordinate the cleaner’s two-motor or multi-motor drive system, depending on the MD configuration. Installation is intended to be performed by a qualified technician, as the electrical box interfaces directly with the robot’s internal wiring and sealed motor units.

Suitability and buying context

This part is suited to owners and service technicians looking to repair a Zodiac Z400 MD4 or MD5 robotic pool cleaner that has developed an electrical fault originating in the control box. It is a cost-effective alternative to full unit replacement and is the recommended repair path by Zodiac for this type of failure. This product is a genuine Zodiac spare part, making it appropriate for warranty-conscious repairs and professional service centres. It is not a universal component and should only be purchased if your cleaner is confirmed to be the Z400 MD4 or MD5 configuration.
