Step by step
-
1 Power and water off
Breaker off, under sink dishwasher stop valve closed. Verify the panel is dead.
-
2 Remove the kick panel
Two to four screws under the door. The inlet valve is at the front left or right where the braided supply line arrives.
-
3 Disconnect with a pan underneath
Photo everything. Wrench the supply line off the valve (water will follow), squeeze the clamp on the outlet hose, and unplug the wire connectors.
-
4 Swap the valve
Unscrew its mounting bracket, transfer to the new valve, and reconnect hose, wires, and supply line, snug, not brutal, on the brass fitting.
-
5 Leak check before the panel goes back
Open the stop valve, watch the connections through a full fill cycle, then reinstall the kick panel.
