Eheim Repair Kit Priming System for Professional 3e & 5e – 2076 / 2078 / 2178 (8002104)

The Eheim Repair Kit Priming System (8002104) is a genuine OEM repair kit containing all the mechanical components needed to restore the priming system on the Eheim Professional 3e and compatible Professional 5e external canister filters. The priming system is the push-button mechanism that allows the filter to self-prime without siphoning — when this system fails or becomes worn, the filter can no longer prime correctly and water circulation stops.

This repair kit includes the complete priming system assembly with screws, allowing a full mechanical restoration of the priming button and housing. The kit restores full push-button priming functionality so your filter starts reliably every time.

Important note: The sealing rings for the priming system are not included in this kit. If your priming system is also leaking, order the Eheim RepairKit Sealings Priming System (8002105) separately for the complete repair.
