LG refrigerator repair Tucson technicians get a steady stream of calls about ice makers that overflow with water. The tray and bucket fill until water spills over and freezes into a mess. The cause is almost always a water control problem, and A Plus Appliance Repair can pinpoint it quickly. When your LG ice maker keeps overflowing, too much water is entering each fill cycle. Or the fill is not shutting off when it should. That extra water freezes into clumps, overflows the tray, and can leak into the freezer or onto your floor. The good news is that the causes are a short, identifiable list. This guide walks through each one and what you can check yourself. It also explains when to call for professional LG refrigerator repair Tucson service at 520-485-5885.
How the Ice Maker Fill Is Supposed to Work
Understanding the normal cycle makes the problem clear. When the ice maker calls for water, the water inlet valve opens for a set time. Water flows through a fill tube into the ice tray. Then the valve closes.
The amount of water depends on two things. One is how long the valve stays open. The other is the water pressure in your line. The tray overflows if the valve stays open too long or lets water through when it should be closed. High pressure can do the same. So an LG ice maker overflowing with water is almost always a story about the valve, the pressure, or the control that times the fill.
The Most Common Cause: A Faulty Water Inlet Valve
The water inlet valve is the leading suspect. This electrically controlled valve opens to let water in and closes to stop it. Over time it can wear out or get stuck partially open. Mineral scale from Tucson’s hard water often builds up inside it and keeps it from sealing.
When the valve does not close fully, water keeps dripping into the ice tray between cycles. The tray slowly overfills until it overflows. A valve stuck open is the single most common reason for an LG ice maker overflowing with water. Replacing it is a job for a technician because it involves both water and electrical connections. It is a common and fixable repair.
Check Your Home’s Water Pressure
Water pressure matters more than most people realize. LG refrigerators are designed to work within a specific pressure range. That range generally starts at 20 psi and should not be excessively high. If your home’s water pressure is too high, each fill cycle forces in more water than the tray can hold. The tray overflows even when the valve works. Low pressure causes other ice maker problems instead.
If your ice maker started overflowing after plumbing work or a change in your water supply, pressure could be the cause. A technician can measure the pressure at the fridge. They can also advise whether a pressure regulator is needed.
A Clogged or Frozen Fill Tube
The fill tube carries water from the valve into the ice tray. In Tucson’s hard water, mineral buildup can partially clog this tube. If cold air reaches it, water can freeze inside and redirect the flow.
A clogged or frozen fill tube can send water outside the tray instead of into it. That looks like overflowing. Thawing a frozen tube and clearing the buildup can solve it. If freezing keeps coming back, a deeper airflow or seal issue is likely. That needs a closer look.
The Ice Maker Assembly or Water Level Control
The ice maker assembly controls the timing of each fill. On some LG models, a sensor or optic system measures the water level or ice level. Suppose the control that times the fill fails. Or suppose a level sensor misreads. The valve can then stay open too long and overfill the tray.
In these cases the valve and pressure are fine. The faulty part is the control telling them what to do. Diagnosing this means testing the ice maker assembly and its sensors. A technician does this to decide whether the assembly needs replacing.
Make Sure the Refrigerator Is Level
A refrigerator that is not level can tilt the ice tray. Water then pools to one side and spills before the tray is full. This is an easy thing to check.
If your fridge was recently moved or installed, or sits on an uneven floor, set a level on top. Adjust the leveling feet so the unit sits flat, with a very slight backward tilt. A level fridge keeps the tray sitting correctly. Water then fills and freezes the way it should. This simple check is worth doing before you assume a part has failed.
What You Can Safely Check Yourself
The homeowner checklist is manageable. Confirm the refrigerator is level and adjust the feet if needed. Look for ice or water spilling outside the tray, which points to the fill tube. Check whether the overflow started after plumbing work, which points to water pressure. Inspect for obvious mineral buildup if you can reach the fill area.
You can also turn the ice maker off for a while. That stops the overflow and lets any ice thaw while you arrange a repair. Most real fixes involve water and electrical work. Replacing a stuck inlet valve or a faulty ice maker assembly is best left to a technician. Still, these checks help you and the technician narrow the cause.
Why Tucson Hard Water Is Often Behind It
Tucson’s hard water is a recurring theme in ice maker problems. The high mineral content leaves scale inside the water inlet valve. That keeps the valve from sealing fully and lets water drip through between cycles. Scale also builds up in the fill tube and water line. It narrows them and disrupts the flow.
This is why LG ice maker overflow problems are so common locally. A whole house water softener reduces the mineral load on every appliance that uses water. Periodic attention to the valve and water line also helps. In a hard water city, this is maintenance worth staying ahead of.
When to Call for LG Refrigerator Repair in Tucson
Suppose the fridge is level and the overflow continues. The cause is then almost certainly one of four things. Those are a faulty water inlet valve, a water pressure problem, a clogged fill tube, and a failed ice maker assembly. Most of these need professional tools and testing.
This is where A Plus Appliance Repair helps. Our technicians test the valve, measure your water pressure, and inspect the fill system. We determine whether the valve or the ice maker assembly is at fault. Then we complete the repair and back it with a warranty.

Keep the Ice Maker Healthy in Hard Water
Hard water is behind so many ice maker problems here that a little upkeep goes a long way. Staying ahead of mineral scale on the water inlet valve and fill line keeps the valve sealing properly. That prevents the slow overfilling that leads to overflow.
A whole house water softener reduces the scale load on the ice maker and every other water appliance. It also helps to keep the freezer at the right temperature so the fill tube does not freeze.
Our guide on how hard water causes problems in Tucson explains the mineral issue. It affects ice makers, dishwashers, and water valves alike. It also shows why local appliances need this attention more than most.
The Bottom Line
An LG refrigerator ice maker overflowing with water comes down to too much water entering, or a fill that will not shut off. The usual causes are a stuck water inlet valve, high water pressure, a clogged or frozen fill tube, a failed ice maker assembly, or an unlevel fridge. Check the level and look at where the water is spilling. Then call for professional LG refrigerator repair Tucson service for the valve and assembly repairs. In hard water Tucson, scale on the valve is the most common culprit. Staying ahead of it keeps your ice maker working.
Frequently Asked Questions
Why is my LG refrigerator ice maker overflowing with water?
The most common cause is a faulty water inlet valve that stays stuck partially open and lets water drip into the tray between cycles until it overflows. High water pressure, a clogged fill tube, a failed ice maker assembly, or an unlevel fridge can also cause it.
Can hard water cause my LG ice maker to overflow?
Yes. Tucson’s hard water leaves mineral scale inside the water inlet valve, which keeps it from sealing fully so water keeps dripping in. Scale also builds up in the fill tube. This makes overflowing ice makers very common locally, and a water softener helps.
How do I stop the overflow right now?
Turn the ice maker off to stop the fill, and let any ice in the tray thaw so it does not keep spilling. This is a temporary step while you arrange a repair. Shutting off the water supply to the fridge also stops the flow if the valve is stuck open.
Could my water pressure be the problem?
Possibly. LG refrigerators are designed for a specific pressure range, generally at least 20 psi and not too high. If pressure is too high, each fill forces in too much water and overflows the tray. If the problem started after plumbing work, pressure is worth checking.
Why is water spilling outside the ice tray?
That usually points to a clogged or frozen fill tube redirecting the water, or an unlevel refrigerator causing the tray to pool water to one side. Check that the fridge is level, and have the fill tube inspected if it keeps happening.
Is a leveling problem really a cause?
Yes. If the fridge is not level, the ice tray sits at an angle and water spills before the tray is full. Use a level on top and adjust the feet so the unit sits flat with a slight backward tilt, especially after a move or installation.
Do I need to replace the whole ice maker?
Not always. Often the fix is a water inlet valve, which is cheaper than the full assembly. Only when the ice maker assembly or its water level control is faulty does the assembly itself need replacing. A proper diagnosis determines which part is at fault.
When should I call a professional?
Call when the fridge is level but the overflow continues, since that points to a valve, pressure, fill tube, or assembly problem that needs testing. A Plus Appliance Repair handles these with warranty-backed LG refrigerator repair Tucson service. Call 520-485-5885.
