KitchenAid Ice Maker DR Error: Drain Problem
What Does KitchenAid Ice Maker Error Code DR Mean? DR on a KitchenAid ice maker stands for Drain. The unit has detected that meltwater and harvest overflow are accumulating rather than draining through the drain system. On built-in ice makers, a small amount of water drains during every harvest cycle and from ice melting in […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Maybe. Minor drain restriction is not dangerous but produces ongoing leaks. Severe drain backup can damage surrounding cabinetry. Address promptly.
Can I reset the code?
Yes. Cleaning the drain and restoring flow clears DR on the next cycle. Manual reset is not required.
When to stop immediately?
Stop if you notice: Water leakage has reached surrounding cabinetry or flooring, Drain cleaning has not restored flow.
Symptoms You May Notice
Standing water in the bottom of the ice bin
A pool of water has accumulated in the bottom of the storage bin rather than draining through the drain plug. The water may be actively overflowing toward the cabinet edge.
Water leaking from underneath the ice maker
Water appears on the cabinet floor or surrounding floor in front of the ice maker — meltwater and fill overflow are making their way out of the cabinet rather than through the intended drain.
Unpleasant odor from the ice bin area
Stagnant water that has not drained properly begins to develop bacterial growth within a few days, producing a musty or rancid smell from the bin or drain area.
Possible Causes
Drain line clogged with ice or debris
The drain tube from the ice bin has become blocked by ice formed inside the tube, mineral scale, or organic debris. The drain cannot handle the meltwater volume and water backs up.
DIY PossibleDrain pump failed (on gravity-fed units without pumps: drain line frozen or blocked)
Units with a drain pump have a small pump motor that has failed or lost prime. On gravity-fed installations, the drain line itself has frozen or accumulated enough scale to lose flow.
Requires ProfessionalDrain opening or trap plugged with biofilm
A biofilm of bacteria and yeast has built up at the drain opening or in the trap, gradually restricting flow until the ice maker cannot keep up. Regular cleaning prevents this.
DIY PossibleSafe Checks You Can Do
-
1
Empty the bin and clean the drain opening
Remove all ice and water from the bin. Locate the drain opening at the bottom of the bin. Flush it with a warm solution of one part white vinegar to three parts hot water to break up biofilm and scale buildup.
A small bottle brush can help scrub the drain opening directly. Avoid pushing debris deeper into the line — draw material out if possible.

2
Verify drain tube routing and temperature
For ice makers installed in garages or unheated basements, verify the drain tube is not running through cold areas where water can freeze inside it. Insulate or reroute any sections that pass through cold zones.
A frozen drain tube resolves itself once warmed, but will refreeze unless the underlying temperature issue is fixed.
When to Call a Professional
Contact a qualified technician if:
- Drain pump tested non-functional on a bench
- Drain line frozen due to routing or insulation failure
- Complete drain replacement required due to unreachable blockage
