Hard mineral deposits may not always be visible, but can wreak havoc on sensors.
Before cleaning Opal, turn off and unplug the unit, and let sit for one hour before cleaning.
If you are using a water filter, remove the filter and reinstall the reservoir screen. See if you can dislodge any hard mineral buildup that might be stuck at the top of the ice chute. This residue may not always be visible, but will impede ice production.
Next, fill the reservoir with vinegar to the max fill line, and run up to three cleaning cycles. Or, purchase an Opal Cleaning Kit and follow the instructions inside.
If using vinegar, leave the vinegar in the unit for 18 hours, and set a vinegar-soaked towel on the ice chute overnight to further dissolve any mineral buildup.
Clean the sensors with vinegar, and wipe clean with water. After draining the vinegar, run three rinse cycles, using fresh water for each rinse.
Remember that filters do not affect water hardness, and water softeners can also create buildup that needs to be cleaned. For the best results, we recommend always using distilled water or a mixture of distilled and tap water with Opal.
