Look for water in the bin and on the floor and wipe it up; keep clear of the outlet if water has reached it. If it comes back, it needs a visit. ### What does drn Err mean on my True ice maker? The drain pump could not clear the water within five minutes. A clogged or kinked drain line is the most common cause; a failed pump is the other. ### Why did my True ice maker switch itself off with drn on the display? True's control shuts the water off and cuts power to the unit when the drain alarm trips, which keeps the bin from overflowing. ### What does drn followed by oFF mean on a True? True says that if a clogged drain clears, the display shows drn and oFF. Turn the unit back on with the power button and watch the next few cycles drain. --- **[Read on the site: True clear ice maker showing drn Err: the drain did not clear](https://icemakerrepair.center/error-codes/true-drn-err/)** **[Book a visit with IceMakerRepair.center](https://icemakerrepair.center/schedule/)**
