Dacor's own installation and user manual documents 4C as a water supply check, tied to the water supply valve being closed, the water supply itself being suspended, or the water inlet valve or line being frozen or clogged by foreign particles left over from installation. Dacor appliance display · also shown as 1C What to do when 4C shows on the appliance ### Kind of code Water supply and drain The new appliance is reporting what it gets from the water connections behind it. A no-water or slow-fill message on the first fill usually means the supply valve is still closed or only half open, or the new line kinked when the unit slid back; a drain message means the drain hose is pinched, pushed too deep into the standpipe, or looped higher or lower than the installation instructions allow. Open the valve fully, straighten the hose, set it to the height the manual gives, and run the cycle again. ### Usually leads to Water supply and shutoff connection New supply lines from a working quarter-turn stop to each water appliance, tested under pressure. ### Shows up as Water Leak After an Install: Close the Supply Valve First A water leak after an install is water on the floor, a drip behind the kick plate or a wet cabinet in the first days after a new appliance was connected to water or a drain. ### Make Dacor Dacor installs range from wall ovens and ranges with a matching hood to column refrigeration and a panel-ready dishwasher in the same run of cabinets. ### Source Dacor dishwasher installation and user manual — water supply check Dacor documents 4C on its current built-in dishwasher installation and user manual. ## Before you book, in this order. Each step comes from Dacor's own guidance for 4C on its appliances. Follow it to the end: the last card says whether this is a visit. 01 Confirm the water supply valve behind the unit is fully open. 02 Check that the house water supply itself has not been shut off or suspended. 03 Inspect the inlet line for debris or a kink left from fitting the unit into place. 04 Run a short cycle once the supply is confirmed clear before assuming any part needs attention. ### Still there? It usually turns into [water supply and shutoff connection](https://applianceinstallation.center/services/water-supply-and-shutoff-connection/). Book with the code and the model number. ### What not to do 4C does not by itself mean the inlet valve has failed. Dacor's own documented causes — a closed valve, a suspended supply, or debris in the line — are all installation-side details rather than a part. ## What you may notice with it.

Confirm the water supply valve behind the unit is fully open. If it comes back, it needs a visit. ### Why would a brand-new dish care machine show 4C the very first time it runs? The most common cause is a supply valve that was never fully opened, or debris left in the inlet line from installation. Both clear once the connection is checked and corrected. ### Does 4C mean the water inlet valve needs replacing? Not on its own; Dacor's documented checks are all about the supply side of the connection, so ruling those out first is the correct order of operations. ### Could cold weather cause 4C on an install in an unheated space? Yes, Dacor names a frozen line as one of the documented causes, which matters for units installed in a garage or an unheated utility space. --- **[Read on the site: Dacor 4C — a water supply check on a new dish care machine](https://applianceinstallation.center/error-codes/dacor-4c/)** **[Book a visit with ApplianceInstallation.center](https://applianceinstallation.center/schedule/)**
