You pull a glass out of the dishwasher in your Winter Park kitchen, hold it up to the light, and it looks cloudy and filmed over even though the cycle just finished. The faucet has a crusty white ring building up where the water hits. The shower door spots the same way. None of that is dirt. It is mineral, and in Orlando it never really goes away.
Central Florida sits on a limestone aquifer, so the water that comes out of your tap is hard to very hard, roughly 8 to 17 grains per gallon depending on where you live. Every time that water sits in a valve, runs through a heating element, or dries on a surface, it leaves calcium and magnesium behind. That mineral load quietly wears on every appliance in the house that touches water. Check out our guide on how long Florida appliances really last. Here is where it shows up, and what actually slows it down.
We see this every week. A homeowner calls because the dishwasher quit cleaning or the ice maker slowed to a trickle, and they assume the appliance is dying. Check out our guide on a dishwasher that will not clean. Half the time the appliance is fine. It is scaled, and scale is not a fault in the machine. It is the water doing exactly what hard water does. Almost all of it is preventable, and most of the early fixes cost a few dollars and an afternoon.
The dishwasher
Hard water is the number one reason your dishes come out cloudy. The minerals in the water bond to glass and leave a white film, and the same scale plugs the tiny jets on the spray arms so the dishwasher sprays weaker over time. You end up rewashing by hand and blaming the machine. Rinse aid and a descale cycle fix most of it. If the film wipes off with vinegar it is scale and reversible, but if it stays it is etching, and etching is permanent, so the move is to head it off before it sets in.
The ice maker and fridge water line
The water line and inlet valve feeding your ice maker are narrow, so scale builds up there fast and chokes the flow. Check out our guide on an ice maker that stops working. That gives you slow ice, hollow or undersized cubes, and ice that looks cloudy instead of clear. The filter clogs sooner too. In Orlando we tell people to swap the fridge filter closer to every four months, not the six the manual says.
The washing machine
Hard water keeps detergent from rinsing out clean, so it dries inside the fibers and leaves your towels stiff and scratchy. It also coats the inside of the machine and the pump with scale, which makes the motor and seals work harder and shortens the life of the unit. Towels that feel like cardboard out of a warm dryer are a hard-water tell, not a detergent problem.
The water heater
This is where hard water does the quietest damage. Minerals settle to the bottom of the tank as sediment, and that layer bakes onto the heating element and insulates it from the water. The popping and rumbling sound you hear is water boiling under the sediment. The tank costs more to run, heats slower, and dies years early. A yearly flush buys it back.
On a tank heater the sediment piles up over the burner or the lower element, so the bottom of the tank overheats while the water stays lukewarm. On a tankless unit the scale coats the heat exchanger and forces it to short-cycle, which is why tankless makers tell you to descale every year on hard water. Either way, a heater that gets ignored on Orlando water runs hot, runs loud, and quits a few years before it should.
Faucets and aerators
That crusty white buildup on the spout and the screen at the tip of the faucet is straight mineral scale. It clogs the aerator screen, splits the stream sideways, and chokes the flow until the faucet dribbles. It is the most visible sign of hard water and the easiest to fix, but it tells you the same scale is forming everywhere you cannot see.
How to fight back in a hard-water house
You will not stop hard water with one trick. The real fix treats the water before it reaches anything, and the rest are habits that keep scale from winning in the meantime. Work down the list.
- Install a water softener. This is the only thing that fixes the cause instead of the symptom. A softener swaps the calcium and magnesium out before the water reaches a single appliance, so the dishwasher, the water heater, the washer, and every faucet stop scaling. A whole-house system runs about $500 to $1,500 installed at retail, and in an Orlando house it pays for itself in appliance life and detergent you stop wasting. Get it plumbed in ahead of the water heater so the heater sees softened water too, and you will notice the difference in your dishes and your showers within a day.
- Use rinse aid in the dishwasher. Rinse aid breaks the surface tension so water sheets off the glass instead of drying into spots. Keep the dispenser filled. It costs a few dollars and it is the single fastest fix for cloudy glasses.
- Run a descale cycle. Once a month, run an empty dishwasher hot with a cup of white vinegar or a citric-acid cleaner to strip the scale off the spray arms and the tub. Do the same with your coffee maker, which scales up even faster because it boils the water. Both descalers cost a few dollars.
- Change the fridge and ice-maker filter every four months. The six-month interval on the box assumes normal water. Orlando water is not normal. Swapping closer to every four months keeps the ice clear and the flow strong. A replacement filter runs about $20 to $50 retail.
- Clean the faucet aerators. Unscrew the screen at the tip of each faucet, drop it in a cup of white vinegar overnight, brush off the loosened scale, and screw it back on. Do it every few months and your water pressure comes back.
- Flush the water heater once a year. Drain a few gallons off the bottom of the tank to clear the sediment before it bakes onto the element. One flush a year is the difference between a heater that lasts and one that quits early.
What hard-water appliance problems cost to fix
Most of the habits above are cheap. Rinse aid and descaler are a few dollars. A fridge water filter is $20 to $50 retail. The water softener is the real spend, at roughly $500 to $1,500 installed retail depending on the size of the house and the system, and that is a one-time cost that protects every appliance at once.
When scale has already done damage, that is a repair. A spray arm caked solid, an inlet valve scaled shut, a heating element coated over. At QLAMA the diagnostic is $90, and we waive it if you go ahead with the repair. We give you a flat price on-site before we touch anything, so there is no hourly meter running. For a sense of dishwasher numbers, Yale Appliance's 2025 service data puts the average dishwasher repair at about $180, with most jobs landing in the $140 to $400 range depending on the part. A scaled valve or spray arm sits in that band.
When to call an Orlando tech
Call when the cheap fixes do not bring the appliance back. If you have run rinse aid and a descale cycle and the glasses are still cloudy, the spray arm or the inlet valve may be scaled past cleaning. Call when the ice maker stays slow after a fresh filter, when the dishwasher will not fill, when the water heater keeps popping after a flush, or when a faucet still dribbles with a clean aerator. Those point to a scaled part that needs to come out, and that is parts-and-tools work most homeowners are not set up for.
Common questions about hard water and appliances
How hard is the water in Orlando?
Hard to very hard. Central Florida sits on a limestone aquifer, so most of the metro runs roughly 8 to 17 grains per gallon. Anything over about 7 grains is considered hard, so nearly every Orlando house is well into hard-water territory and feeling the effects on its appliances.
Why are my glasses cloudy after the dishwasher?
It is mineral film, not soap residue or a broken machine. Hard water leaves calcium on the glass as it dries, and over time it etches a permanent haze. Use rinse aid every cycle and run a monthly vinegar or citric-acid descale cycle, and most of the cloudiness clears up.
Is a water softener worth it in Florida?
In Orlando, yes. With water this hard, a softener protects the water heater, the dishwasher, the washer, and the plumbing all at once, and it cuts the detergent and rinse aid you burn through. A system runs about $500 to $1,500 installed retail, and it usually pays for itself in extended appliance life.
Can hard water ruin my appliances?
It does not fail them overnight, but it shortens their life. Scale insulates the water heater element, clogs valves and spray jets, and makes pumps and motors work harder. An appliance that should last ten years can quit several years early on untreated Orlando water.
How often should I descale my dishwasher and coffee maker?
About once a month in Central Florida. Run the dishwasher empty and hot with white vinegar or a citric-acid cleaner, and descale the coffee maker on the same schedule since boiling water scales it even faster. Staying on a monthly rhythm keeps the buildup from ever locking anything up.
