What Time to Clean light means

The yellow Time to Clean light on the GE Profile 15-inch undercounter nugget ice machine UNC15 (UNC15NJII and UNC15NPRII) is a maintenance reminder. It comes on after 6 months of use and remains on until the system is cleaned, or descaled. Water minerals build up inside the ice-making system over time, and the light asks you to clean before they affect ice production.

Common causes of Time to Clean light

Six months of use have passed
Scale building up in the ice-making system
Cleaning cycle not completed

✓ One safe check you can try

1. Clean the ice making system as described in the Care and Cleaning section. 2. During the cycle the light blinks. 3. When the clean cycle is complete the light goes out. 4. Discard the first ice after cleaning. Keep the door closed during the cycle.

! Why to stop there

If the light stays on after a full clean, the cycle may not have completed or the control needs checking.
If ice is also slow or the motor labors, scale may be heavier than normal.
We descale and test, and we quote in writing first.

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.

Time to Clean lightTime to Clean light questions

Why is the Time to Clean light on?

Six months of use have passed. It stays on until the system is cleaned. It is a maintenance reminder, not a breakdown. Cleaning is quick compared with a repair.

What does the light do during cleaning?

It blinks during the cycle and then goes out when the clean cycle is complete. The light blinks while the cycle runs, so you can tell it is working.

Can I ignore it?

You can for a while, but scale may cut ice production and strain the motor. Cleaning is the cheapest fix. If it stays on after cleaning, call us.
