- • Position the unit near the edge of a counter or sink to prevent slipping while draining liquid.
📋 Step-by-Step Guide (7 Steps)
Drain Existing Water and Remove Removable Parts
Unplug the ice maker and place the rear or bottom drain plug over a sink or catch basin. Pull the silicone drain plug to empty all standing water. Lift out the plastic ice basket and ice scoop.
- • No standing liquid in the bottom reservoir
- • Ice basket and scoop resting on the counter beside the open unit
- • Losing the small silicone drain plug down the sink drain
- • Forgetting to unplug the power cord before draining
Mix and Add Descaling Solution
Reinsert the drain plug firmly. Mix a 1:1 solution of distilled white vinegar and filtered water in a measuring cup, then pour it into the main reservoir up to the maximum fill line.
- • Drain plug fully seated with no drips underneath
- • Liquid level sitting precisely at or just below the 'MAX' ridge inside the tank
- • Overfilling past the MAX line, which can flood the internal overflow chute
- • Pouring solution before the drain plug is fully sealed
Run the Descaling Cycle
Plug the machine in and press the 'Clean' button (or turn on a standard ice-making cycle if your model lacks a dedicated clean function). Let the solution circulate through the water pump and over the metal evaporator fingers for 10 to 15 minutes.
- • Clean mode LED illuminated or water visibly cascading over the evaporator prongs
- • Fluid pumping continuously from reservoir to top tray
- • Allowing the machine to complete a full freeze cycle and eating the vinegar ice
- • Interrupting the cycle before the scale has had time to dissolve
Detail Scrub Interior Surfaces and Sensors
Unplug the machine. Dip a soft toothbrush and cotton swabs into the vinegar solution inside the reservoir, then gently scrub the metal evaporator fingers, infrared sensors, water scoop, and reservoir corners.
- • Metal evaporator prongs are shiny and free of chalky white crust
- • Clear, unclouded optical sensor lenses on both sides of the ice basket bay
- • Using abrasive scouring pads that scratch the plastic and promote bacterial growth
- • Bending the metal evaporator prongs with excessive force
Drain Solution and Hand-Wash Removable Accessories
Pull the silicone plug and completely drain the vinegar solution into your catch basin. While it drains, wash the ice basket and scoop in the sink using warm water and mild dish soap, then rinse thoroughly.
- • All vinegar solution drained from the bottom reservoir
- • Clean, soap-free ice basket and scoop drying on a towel
- • Putting the plastic ice basket in a high-heat dishwasher, which warps it
- • Leaving soapy residue on the scoop or basket
Perform Fresh Water Flush Cycles
Reseal the drain plug, fill the reservoir to the MAX line with clean filtered water, and run a full clean or ice-making cycle. Drain the water completely, then repeat this fresh water flush a second time to remove all vinegar traces.
- • Clear, odorless water exiting the drain port
- • Evaporator fingers and water tray free of any vinegar aroma
- • Running only a single flush, leaving a sour vinegar taste in subsequent ice
- • Skipping the second drain step
Dry Interior and Reassemble
Reinsert and secure the drain plug tightly. Use a clean, dry microfiber cloth to wipe down all internal surfaces, the lid interior, and the exterior shell. Reinstall the dry ice basket and close the lid.
- • Interior walls and reservoir completely dry with no condensation pools
- • Ice basket seated flush inside its mounting tracks
- • Exterior polished with no water streaks
- • Leaving moisture in a closed unit stored in a dark cabinet, causing mildew
- • Leaving the drain plug loose after reassembly
