KitchenAid KUD508ESS1: Ice Maker Not Making Ice in The Woodlands, TX
π Call (346) 512-3688π§ Performed by Alex Z.
The Problem
- β’Ice maker completely stopped producing ice cubes
- β’Loud grinding or buzzing noise coming from the rear of the refrigerator near the water valve
- β’No water filling the ice maker tray even when the ice maker arm was in the down position
- β’Ice maker motor cycling repeatedly but no cubes dropping into the bin
π Diagnosis
On arrival at the 77382 residence in The Woodlands, the KitchenAid KUD508ESS1 presented with a completely inactive ice maker and an audible buzzing noise originating from the rear lower section of the unit β a pattern consistent with a failed water inlet valve struggling to actuate. The ice maker bin was empty and the tray was dry, confirming water was not reaching the mold at all. Using a digital multimeter set to the resistance (Ξ©) function, the technician probed the solenoid coil terminals on the water inlet valve. The reading came back at 0 ohms β a dead short, indicating the solenoid winding had burned out internally. A healthy KitchenAid water inlet valve solenoid on this model typically reads between 200 and 500 ohms. Zero resistance means the coil is shorted and drawing excessive current, which explains both the buzzing sound and the valve's inability to open and allow water flow. The KUD508ESS1 uses a dual-coil inlet valve that feeds both the ice maker and the door water dispenser. On this particular model, the ice maker solenoid coil is the more heavily cycled of the two and is a known wear point, especially in households with hard water β which is common throughout The Woodlands area due to local municipal supply characteristics. The water filter was also found to be heavily clogged and discolored, restricting flow and putting additional strain on the valve. Condenser coils at the rear were coated with dust, reducing overall system efficiency.
π§ The Repair
- βStep 1: Disconnected the KitchenAid KUD508ESS1 from power at the wall outlet and shut off the dedicated water supply line feeding the refrigerator.
- βStep 2: Pulled the unit away from the wall to access the rear panel. Removed the lower rear access cover using a quarter-inch nut driver to expose the water inlet valve and condenser coils.
- βStep 3: Confirmed valve failure by re-testing the solenoid coil terminals with a Fluke 117 multimeter β reading confirmed at 0 ohms (dead short). Photographed the reading for the repair record.
- βStep 4: Disconnected the two water line fittings from the inlet valve β the supply line from the house and the outlet line leading to the ice maker β using a small adjustable wrench. Placed a towel to catch residual water.
- βStep 5: Unplugged the two wiring harness connectors from the valve solenoid terminals. Removed the single mounting screw securing the valve bracket and extracted the failed valve assembly.
- βStep 6: Installed the OEM-compatible replacement KitchenAid water inlet valve. Reconnected water lines and harness connectors, confirmed secure seating on both solenoid plugs.
- βStep 7: Replaced the inline water filter with a fresh OEM-spec filter cartridge. Cleaned the condenser coils thoroughly using a refrigerator coil brush to restore proper airflow and condensing efficiency for the R-134a sealed system charged at 5.75 oz.
- βStep 8: Restored power and water supply. Manually initiated an ice maker harvest cycle. Valve opened cleanly β audible water fill confirmed. After 45 minutes, the first batch of full-sized ice cubes dropped into the bin. Fresh food compartment held 37Β°F, freezer section at 0Β°F β both within spec.
β Result
Within 45 minutes of completing the repair, the KitchenAid KUD508ESS1 was producing full, properly sized ice cubes β noticeably larger than what the homeowner had seen in months, which suggests the clogged filter had been restricting fill volume long before the valve fully failed. Freezer stabilized at 0Β°F, fresh food at 37Β°F. The homeowner in The Woodlands' 77382 area was relieved β they had a family gathering coming up that weekend and were prepared to buy bags of ice. They said the cubes looked better than they ever remembered.
π‘ Technician Notes
KitchenAid refrigerators with ice makers in The Woodlands area are especially vulnerable to water inlet valve failure because local water supply has elevated mineral content. The earliest warning sign specific to this failure is a buzzing or humming noise that starts intermittently when the ice maker calls for water β that's the solenoid coil beginning to short before it fails completely. Most homeowners ignore it for weeks before the ice maker stops entirely. To prevent premature valve failure, replace the water filter every 6 months without exception β a clogged filter forces the valve to work harder on every fill cycle, accelerating solenoid wear. On the KUD508ESS1, the filter bypass pressure can exceed what the valve was engineered to handle long-term. If you hear buzzing from the rear of the unit but ice production hasn't stopped yet, call immediately. A shorted solenoid can trip the refrigerator's control board or damage the water line fitting through repeated pressure spikes. Waiting until the ice maker goes fully silent is waiting too long.
Frequently Asked Questions
Why did my KitchenAid KUD508ESS1 ice maker stop making ice and start making a loud noise?
The most common cause is a failed water inlet valve solenoid. On the KUD508ESS1, the solenoid coil can short internally, reading 0 ohms instead of the normal 200β500 ohm range. When that happens, the valve can't open to let water into the ice maker mold, and the buzzing noise you hear is the shorted coil trying to actuate. Replacing the valve restores full ice production.
How much does it cost to fix a KitchenAid ice maker water valve in The Woodlands TX?
A water inlet valve replacement on a KitchenAid refrigerator in The Woodlands typically runs between $180 and $280 all-in, depending on the valve configuration and whether a filter replacement is needed at the same visit. The KUD508ESS1 uses a dual-coil valve that is moderately priced as an OEM-compatible part. Most repairs including diagnostics are completed within an hour.
What happens if I keep running my KitchenAid refrigerator with a bad water inlet valve?
A shorted solenoid doesn't just stop ice production β it draws abnormal current on every cycle, which can eventually damage the refrigerator's main control board or the wiring harness near the valve. You may also get intermittent water dispenser failure. The longer a shorted valve runs, the higher the risk of a more expensive secondary repair. Address it when the buzzing starts, not after.
Is it worth repairing a KitchenAid KUD508ESS1 or should I just replace it?
A water inlet valve failure is one of the most cost-effective repairs on any KitchenAid refrigerator β the part is inexpensive and the sealed R-134a system is unaffected. Unless the compressor, evaporator, or control board is also failing, repair is almost always the right call on this model. KitchenAid built the KUD508ESS1 with a robust cabinet and sealed system; a single valve failure doesn't change that calculus.
How do I know when to replace my KitchenAid refrigerator water filter and does it really affect the ice maker?
KitchenAid recommends replacing the water filter every 6 months or when the indicator light activates. A heavily clogged filter restricts water flow to the inlet valve on the KUD508ESS1, forcing it to work against higher backpressure on every ice maker fill cycle. Over time, this accelerates solenoid wear. In The Woodlands, where water mineral content is higher than average, sticking to a 6-month schedule is genuinely protective β not just a manufacturer upsell.
