What to do when Blank display / OFF after power interruption shows on the applianceKind of codeWater 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.

Before you book,
in this order.
Each step comes from DCS's own guidance for Blank display / OFF after power interruption on its appliances. Follow it to the end: the last card says whether this is a visit.
Check the drain line for kinks, low spots or debris between the unit and the point it empties into.
Re-run the 3-quart drain test: pour water into the ice storage bin and confirm it drains completely without the display going blank.
Wait for power to restore on its own once the restriction is cleared; the unit signals recovery with a startup chime and shows OFF.
If the display keeps going blank with a confirmed clear drain, book a visit.
Still there?
It usually turns into water supply and shutoff connection. Book with the code and the model number.
What not to do
A blank display right after the drain test is the safety feature working as designed, not a control board failure; it is a different condition from a unit that stays permanently blank with no chime after power is restored, which does need a visit.

A booking moves faster with three things: the message exactly as the display shows it, the model number from the carton or the rating plate, and the moment it first appeared. With those, the office can tell whether it is a setup step or a connection to put right, and send the part that fixes it.
