There are a few steps you can take to troubleshoot and potentially fix the issue. First, check if the water supply line is properly connected and not kinked or blocked. Ensure that the water valve behind the fridge is turned on as well. If these basic checks don’t solve the problem, it could be due to a faulty water filter. Try replacing the filter with a new one and see if that resolves the issue.
If none of these steps work, it might be time to call a professional technician. They will have specialized knowledge and tools to diagnose and repair any underlying issues with your fridge’s water dispenser.
