Expert Water Line Diagnosis
Water line issues require thorough inspection of the entire water supply system, from the household connection to the ice maker. Our certified technicians can quickly identify blockages, leaks, or valve problems.
Step-by-Step Solutions
Check Water Supply
Verify that the household water supply valve is fully open and water pressure is adequate (minimum 20 psi required).
Replace Water Filter
A clogged water filter is the most common cause. Replace the filter if it hasn't been changed in the last 6 months.
Inspect Water Line
Check the water line for kinks, frozen sections, or blockages. Straighten any kinks and thaw frozen lines.
Test Water Inlet Valve
Use a multimeter to test the water inlet valve for proper operation. Replace if defective.
