Ice maker drain pump problems

Pump models are used when there is no gravity drain (e.g. draining to a sink). They need correct hose routing within the stated rise/run limits and tight connections. A pump that cannot discharge can stop production or cause leaks.

Countertop ice maker shows 'Add Water' with water in the reservoir

These units detect water with a float, probe or wire sensor in the reservoir and a small pump that lifts water to the tray. Scale on the sensor, a blocked reservoir screen, a stuck float, very pure water or a weak pump can all trigger a false Add Water.

Undercounter ice maker: ice slab will not release or sticks on the cutting grid

Grid-cutter (slab) ice makers freeze a sheet, release it during harvest and let a heated wire grid cut it into cubes. Most release problems come from an unlevel cabinet, scale on the evaporator plate, or a cutting grid that is unplugged or not heating. Harvest switches and probes are next.

Undercounter ice maker not making ice

Check power, water supply and pressure, drain (pump models stop when they cannot drain), bin sensor, cleaning status, condenser and room temperature. Scale is the most common cause on older machines.
