Hotpoint Dishwasher Error Code C6 — Water Inlet Valve Failure
What this means
The C6 error code on Hotpoint dishwashers indicates the water inlet valve is not opening or the machine is not detecting adequate water flow. This can be caused by a closed supply valve, low water pressure, a clogged inlet screen, or a failed inlet valve solenoid. The dishwasher will not start a wash cycle without adequate water.
Step-by-step fix
4 stepsCheck the water supply valve
Locate the dishwasher supply shut-off valve under the kitchen sink. Make sure it is fully open (turned counterclockwise). Run the kitchen faucet to confirm you have adequate water pressure.
If you have a dual-outlet valve under the sink, make sure you are checking the outlet that feeds the dishwasher, not just the faucet.
Inspect the supply line
Check the braided supply hose running from the valve to the dishwasher for kinks, damage, or loose fittings. Tighten any loose connections.
A very old rubber supply line can collapse internally even if it looks fine on the outside. Replace with braided stainless steel.
Clean the inlet valve screen
Turn off the supply valve. Disconnect the supply line from the dishwasher inlet valve. Remove the small mesh screen inside the valve inlet with pliers and rinse it clean of sediment.
If the screen is severely clogged with mineral scale, soak it in white vinegar for 15 minutes before rinsing.
Test the water inlet valve
Reconnect everything and run a cycle. If water still does not enter, the inlet valve solenoid has likely failed. With a multimeter, test the valve solenoid coil for continuity. Replace if open.
On Hotpoint dishwashers, the inlet valve is usually located behind the lower front panel on the left side.
When to call a professional
If the valve has failed and needs replacement, the repair involves water line disconnection and electrical connections. A plumber or appliance tech can handle this if you prefer not to DIY.
