What to do now
Stop before starting another cycle and check only visible, user-accessible drain setup issues.
The washer is not draining properly; Whirlpool notes this can sometimes be an installation problem. Stop before starting another cycle and check only visible, user-accessible drain setup issues. Do not keep running the appliance if the code returns or a safety sign appears.
Region: United States. This page does not generalize the code to every Whirlpool washer.
The washer has detected that draining is not happening properly. In the cited top-load HE article, Whirlpool says this can sometimes be an installation problem.
Confirmed: Whirlpool documents drn for top-load HE washers as a draining problem. The official article gives a narrow meaning and warns that installation can be involved, so Pelledor keeps the page focused on safe, visible checks rather than diagnosing a failed pump.
Stop before starting another cycle and check only visible, user-accessible drain setup issues.
Only after safe supply checks and only if the code clears.
Stop using the washer if water remains in the basket, water leaks, the drain hose is unsafe, power trips, or the code returns after visible drain checks.
Contact service or an installer if the visible drain setup looks correct but drn returns or the washer cannot remove water.
No reset procedure is published here because the current source does not document one for this scope.
Do not repeatedly run cycles if water remains in the washer or the drain route looks restricted.
Record the model label, whether water remains in the basket, drain hose position, any recent installation changes, and when drn appears in the cycle.
