Hi @speedy20741
Did you mean an LG LD8874ST?

Here's an image of the wiring diagram seen on p.65 of the service manual that may help.

Disconnect the power to the dishwasher, remove the harness cable plug from the control board's RD6 connector and then connect an Ohmmeter across pins 1 and 2 (yellow and blue wires) of the cable harness plug and test if the switch is operated when it shouldn't be.

If there is a problem with the switch inside the rinse aid dispenser, search online for MCU61861001 (examples only) to find suppliers that suit you best.

To remove the dispenser see p.19 of the manual.
