KitchenAid KUID508ESS2 freestanding ice maker Parts

For the KitchenAid KUID508ESS2 freestanding ice maker, the most reliable “reset” is a power reset: turn the unit off, remove power briefly, then restore power and restart ice making. Exact reset button steps vary by control style, so we follow the model’s documented procedure in the KUID508ESS2 owner’s manual.

Quick reset steps (safe for most situations)

• Turn the ice maker OFF at the control panel.
• Unplug the unit (or switch OFF the breaker) for 2 to 5 minutes.
• Restore power.
• Turn the ice maker ON and allow time for the first harvest cycle.
• If the unit has a dedicated reset sequence, follow the steps in the KUID508ESS2 owner’s manual.

If it still will not make ice

A reset will not fix a water supply or component problem. Check these common causes first:

• Water supply valve is open and household water pressure is adequate.
• Water line is not kinked and the inlet screen is not clogged.
• Unit is level and has proper airflow around the condenser area.
• Ice thickness or bin sensing is not being blocked by ice buildup.
• Drain is working (standing water can stop production on some installations).

Parts that can be involved (when symptoms point to a failure)

If troubleshooting points to a specific component, these are common reset-related suspects on this model:

Symptom after reset	What it can indicate	Example compatible part
No response, dead display, erratic operation	Control not powering or not processing inputs	Ice maker electronic control board W11034363
Runs but poor circulation over evaporator plate	Weak or failed recirculation	Pump, recirculating (includes sensor) W11542867
Water will not drain, unit stops or alarms	Drain system issue	Ice maker drain pump W11542868

Why it matters

A proper reset clears minor control glitches and restarts the harvest sequence, but it also helps us confirm whether the issue is a temporary control lockup or a real problem with water flow, draining, or the electronic control.

A KitchenAid freestanding ice maker like model KUID508ESS2 does not have a single published “lifespan” we can verify from model-specific documentation; real-world service life varies widely. In practice, consistent cleaning, good water quality, and proper airflow usually make the biggest difference in how long it runs reliably.

What typically shortens service life

• Hard water scale buildup on the evaporator and water system
• Poor ventilation that makes the compressor run hot
• Skipped cleaning that leads to slime, odor, and restricted water flow
• Drain issues that leave standing water and overwork the pump
• Heavy, continuous demand that increases wear on moving and sealed-system parts

Model-specific maintenance to focus on (KUID508ESS2)

We recommend following the cleaning and care instructions in the KUID508ESS2 use & care manual. If you are installing or relocating the unit, use the KUID508ESS2 installation guide to confirm ventilation clearances and drain setup.

Maintenance focus	What you are preventing	What you may notice if it is overdue
Cleaning and descaling per manual	Scale, slow harvest, poor ice release	Smaller cubes, longer cycles, more noise
Airflow and condenser area kept clear	Overheating, long run times	Hot cabinet sides, frequent running
Drain path stays open	Standing water, pump strain	Water in bin area, slow draining

Water filtration for this model

For KUID508ESS2, a compatible replacement filter is listed in the parts for this model: refrigerator water filter F2WC9I1. Using the correct filter helps reduce sediment and scale that can shorten component life.

• Replace the filter on a schedule that matches your water conditions and usage
• If ice tastes off or production slows, check the filter and water supply first
• Always match parts by model compatibility, not by appearance

Why it matters

Most ice maker problems start as performance changes (slow production, thin or cloudy ice, louder operation). Staying on top of cleaning, airflow, and filtration can reduce stress on key parts like the compressor, recirculating pump, and control system.

If your KitchenAid KUID508ESS2 freestanding ice maker runs but does not make ice, the most common causes are no water getting to the reservoir, a failed recirculation pump, or a cooling/control problem that prevents the evaporator plate from freezing. Use the checks below to pinpoint which system is stopping ice production.

Quick checks first (no tools)

• Confirm the unit is powered on and not in a delayed or cleaning mode (see the KUID508ESS2 owner’s manual).
• Make sure the water supply valve is fully open and the supply line is not kinked.
• Check the water reservoir: empty points to a fill/supply issue; full points to circulation/freezing issues.
• Look at the evaporator plate: if it stays dry while the reservoir is full, water is not being pumped over the plate.
• Allow time after a restart; many freestanding ice makers need a full cycle before the first harvest.

What the symptoms usually mean

What you observe	Most likely area	What to do next
Reservoir empty	Water supply or inlet valve	Verify house water, valve open, line not frozen/blocked
Reservoir full, evaporator plate dry	Recirculation system	Listen for pump operation; inspect for blockage
Water flows over plate but no ice forms	Cooling or temperature sensing	Check condenser airflow, thermistor, control issues
Ice forms but will not release/harvest	Grid/harvest or control	Inspect cutter grid and control functions

Parts that commonly fix “runs but no ice” on this model

If your checks point to a failed component, these model-matched parts are common suspects:

• Pump, recirculating (includes sensor) W11542867: moves water from the reservoir across the evaporator plate.
• Thermistor WPW10511923: reports temperature to the control so the unit knows when to freeze/harvest.
• Ice maker electronic control board W11034363: manages fill, freeze, and harvest timing.
• Ice maker evaporator WPW10218037: the freezing surface; issues here can prevent proper ice formation.

Why it matters

An ice maker can “run” (fan, compressor, lights) even when one step in the cycle fails. Separating water supply, water circulation, and cooling/control problems prevents unnecessary part replacement and gets KUID508ESS2 back to making ice faster.
