PRODUCT OVERVIEW
Jackson 5700-002-81-87 Plate is an original Jackson replacement component engineered for commercial dishwashers, supporting efficient operation, consistent results, and reduced downtime in busy kitchens.

Details
This is an OEM replacement Seal Plate (part# 5700-002-81-87) designed for Jackson JSP series undercounter dishwashers (models JSP1, JSP2, JSP3, JSP4), part of Jackson's commercial warewashing equipment line. The seal plate creates a critical interface between the pump assembly and the water distribution system, providing precision alignment and sealing surfaces for proper water flow control during wash cycles.
Seal plates degrade due to mechanical wear from pump cycling, corrosion from mineral-laden water, and deterioration of sealing surfaces from detergent exposure. Symptoms of seal plate failure include water leaking from beneath the distribution system, uneven spray patterns with some nozzles weaker than others, water bypassing the spray system entirely, and reduced overall cleaning effectiveness. Neglecting to replace a worn seal plate permits progressive water misdirection, reduces wash quality, wastes water, and eventually forces equipment shutdown for repair.
Installation requires disassembling the water distribution system and pump coupling, a task best performed by qualified Jackson service technicians. The seal plate is a direct fit replacement requiring careful removal from its mounting location using appropriate hand tools. Before installation, inspect the mating surface of the pump assembly for damage or warping that could prevent proper seating. Clean all surfaces thoroughly before positioning the new seal plate, ensuring precise alignment with mounting holes. Tighten fasteners in a crisscross pattern to provide even compression, then test water delivery patterns during the first operational cycle.
