How to Replace the Water Inlet Valve on a Maytag MDB8959SKZ Dishwasher — Step-by-Step Instructions
Step-by-step instructions for the Maytag MDB8959SKZ (dishwasher, top control, dual power filtration). Parts and access points can differ slightly by production year — the steps below cover the common layout for this platform, and the model notes flag its quirks.
Kill the dishwasher’s breaker AND close the under-sink stop valve before starting. The valve sits behind the kick panel next to line-voltage wiring.

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.

No fill with a new valve means the float switch or control isn’t calling for water — quick meter work for a pro, guesswork without one. If you'd rather skip it entirely, find a dishwasher repair pro near you →
