Sub-Zero Designer Ice Maker Code 95-D-01: drain pump float tripped repeatedly

What 95-D-01 means

On Sub-Zero Designer undercounter ice makers, the DEU1550I and DEU1550IP, 95-D-01 means the drain pump emergency float has triggered several times in a row. The float rises when water builds up in the drain pump reservoir, warning that water is not leaving fast enough. The control flags it after repeated triggers. Owners may see 95-D-01 on the display and ice production pause.

Common causes of 95-D-01

A drain line that is kinked, clogged or routed too high
A drain pump that is not clearing water fast enough
A float that sticks in the raised position
Debris in the drain pump reservoir

✓ One safe check you can try

1. Check the drain line under the unit for kinks or sags you can see. 2. Make sure the drain outlet is not blocked. 3. Turn the breaker off for a minute and back on. 4. If 95-D-01 returns, stop using the unit and call us.

! Why to stop there

The pump and float sit inside the base of the ice maker
Water near wiring must be handled safely
A clogged drain may need specific cleaning tools

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

95-D-0195-D-01 questions

What does 95-D-01 mean on my DEU1550IP?

The emergency float in the drain pump has triggered multiple times in a row. That means water has been backing up in the reservoir instead of draining away.

Is there a risk of leaks?

The float exists to prevent overflow. If it keeps tripping, water is not draining correctly, so check for moisture around the unit and book service.
