KitchenAid KUIX335HPS01: Ice Maker Stopped Working and Preventive Maintenance in Memorial, TX
📞 Call (346) 512-3688🔧 Performed by Serhii T.
The Problem
- •Ice maker stopped producing ice completely
- •No water reaching the ice maker tray despite the unit being powered on
- •Ice maker had been serviced under warranty by KitchenAid technicians for the same issue within the past year
- •Interior buildup visible on evaporator components and ice maker housing from skipped maintenance cycles
🔍 Diagnosis
I reached out to this Memorial customer proactively. I had completed a full cleaning on their KitchenAid KUIX335HPS01 nine months prior, and based on that schedule I called to check in. The customer told me that in the months between our visits, the ice maker had stopped producing ice entirely. They were still under warranty, so they called KitchenAid directly. The KitchenAid technicians who responded diagnosed a severely clogged internal water filter as the reason the ice maker was receiving no water flow. The ice maker module itself was functional. The water line pressure to the unit dropped below the minimum threshold required to trigger the fill cycle, which is typically around 20 PSI on this model. Because the customer uses a whole-house filtration system, the KitchenAid service team advised them to bypass the internal filter altogether and leave the filter slot empty. I disagreed with that advice after inspecting the interior. When I opened the unit and examined the ice maker compartment and surrounding surfaces, I found scale deposits and residue consistent with unfiltered water passing through the system. The whole-house filter does reduce sediment but does not eliminate all mineral content at the point of use. Bypassing the internal filter entirely puts that mineral load directly onto the ice maker components, water valve screen, and fill tube. I showed the customer photos of the interior buildup and explained the risk of accelerated scaling on the fill tube and valve inlet screen over time.
🔧 The Repair
- ✓Step 1: Inspected interior of KitchenAid KUIX335HPS01 including ice maker compartment, fill tube, water valve inlet screen, and all accessible evaporator surfaces before starting the cleaning.
- ✓Step 2: Photographed interior condition before cleaning to document scale buildup and residue on the ice maker housing, fill tube entry point, and condenser area.
- ✓Step 3: Cleaned the condenser coils using a coil brush and low-pressure air to remove dust and debris that had accumulated over the nine-month interval.
- ✓Step 4: Cleaned the ice maker compartment interior walls, bin, and ice chute using KitchenAid-approved cleaning solution to remove mineral deposits and biofilm.
- ✓Step 5: Inspected the water valve inlet screen for scale buildup related to unfiltered water flow and cleared any partial restriction present.
- ✓Step 6: Inspected the fill tube for signs of mineral bridging or partial freeze that the previous no-filter period could have accelerated.
- ✓Step 7: Advised the customer to reinstall an internal water filter and replace it every five to six months instead of the standard nine-month cycle, given their Houston-area water mineral content and high-use pattern.
- ✓Step 8: Photographed the interior after cleaning to provide the customer with a clear before-and-after comparison. Ice maker was confirmed running through a full fill and freeze cycle, producing a complete batch of ice within approximately 90 minutes of completing service.
✓ Result
The KitchenAid KUIX335HPS01 in this Memorial home left the visit in clean condition with the ice maker producing normally. The customer understood why skipping the internal filter had contributed to the warranty call and agreed to reinstall one and change it on a five-to-six-month schedule. They appreciated seeing the before-and-after photos side by side. The customer mentioned they had no idea the interior looked that different after a proper cleaning. No warranty-related issues were present at the time of this visit.
💡 Technician Notes
KitchenAid undercounter ice makers like the KUIX335HPS01 are sensitive to water flow pressure and water quality simultaneously. The internal filter does two jobs: it protects the water valve inlet screen from sediment, and it reduces dissolved minerals that cause scale buildup in the fill tube and ice tray. If the filter clogs fast because of high water use or poor incoming water quality, the right fix is a shorter replacement interval, not filter removal. A whole-house filter does not eliminate this problem at the point of entry into the ice maker. The early warning sign to watch for is smaller-than-normal ice cubes before production stops entirely. That indicates restricted water flow, usually a partially clogged filter or a partially blocked valve screen. Do not wait for production to stop completely. If your KUIX335HPS01 ice maker goes from full batches to partial batches over two to three weeks, call a technician before the valve screen fully blocks.
Frequently Asked Questions
Why did my KitchenAid KUIX335HPS01 ice maker stop making ice even though I have a whole-house water filter?
A whole-house filter reduces sediment but does not eliminate dissolved minerals. The internal filter on the KUIX335HPS01 provides a second layer of protection right at the water valve inlet. If that internal filter clogs, water pressure to the ice maker drops below the minimum threshold needed to trigger the fill cycle. The fix is replacing the internal filter more frequently, not removing it.
How much does it cost to service a KitchenAid undercounter ice maker in Houston and how long does it take?
A preventive maintenance visit for a KitchenAid KUIX335HPS01 in the Houston area typically runs between 120 and 180 dollars depending on condition and parts needed. A full cleaning with condenser, ice compartment, and fill tube service takes roughly one to two hours on-site. If a water valve or fill tube replacement is needed, add parts cost and an additional 30 to 45 minutes.
What happens if I skip regular cleaning on my KitchenAid KUIX335HPS01 ice maker?
Skipped maintenance on the KUIX335HPS01 leads to scale buildup inside the fill tube, mineral deposits on the ice tray, and eventually a clogged water valve inlet screen. Left long enough, the fill tube narrows enough to restrict water flow, and the ice maker stops producing. At that point you are looking at a service call, possible valve replacement, and a unit that had been under warranty but failed from avoidable buildup.
Is it worth repairing a KitchenAid KUIX335HPS01 ice maker or should I replace the unit?
For most water flow and ice production failures on the KUIX335HPS01, repair is the right call. The sealed system on this unit is durable and the compressor has a long service life when maintained. Water valve failures, clogged filters, and scale-related issues are all serviceable repairs well under 300 dollars. Replacement only makes sense if the compressor or sealed system fails and the unit is already eight or more years old.
How often should I replace the water filter in my KitchenAid KUIX335HPS01 in Houston?
KitchenAid recommends every six months as a standard interval, but Houston water quality and high household ice use load that filter faster. For homes with a high-use pattern or homes that also run a whole-house filter, I recommend replacing the internal filter every five to six months. Waiting nine months or longer is what leads to the restricted flow and no-ice condition I see repeatedly on this model in the Memorial and Memorial area.
