7 Common Tankless Water Heater Problems We Repair Across Central PA
Central PA sits on limestone, which means our water runs hard. Those dissolved minerals build up as scale inside the heat exchanger, and tankless units are more sensitive to it than any other appliance in your home. Then winter hits. Cold groundwater means the unit has to work that much harder just to get you to the right temperature. On top of that, many homeowners have their tankless unit mounted somewhere unheated, like a garage or a crawl space. Put it all together and it’s no surprise when these units start to act up.
Here’s what we see and fix most often at Pronto Plumbing, Heating, Air & Drains:
- No Hot Water at All: No hot water is usually attributed to an ignition failure, a tripped breaker, a gas supply problem, or a flow sensor that isn’t registering demand. You can count on our pros to diagnose the actual cause instead of guessing.
- Temperature Fluctuations: The cold water sandwich. The water is cold, then hot, and then cold again. Or maybe vice versa. Sometimes it’s just a pipe lag between uses. But when it happens every single time, a failing flow sensor or scale buildup is usually behind it.
- Scale & Hard Water Buildup: The number one tankless killer around Central Pennsylvania is scale and hard water buildup. Scale coats the heat exchanger, forces the unit to run hotter, drives up your gas bill, and can even crack the exchanger if you let it go too long. A professional descaling flush from Pronto will clear it right out.
- Error Codes on the Display: Error codes displaying on your heater? Your unit is trying to tell you something. Flame failure, overheating, venting blockage, and sensor faults all mean different things. Fortunately, the plumbing pros at Pronto know exactly how to read them.
- Rumbling, Popping, or Kettling Sounds: Odd noises almost always mean mineral buildup where it doesn’t belong.
- Water Leaking Around the Unit: If you notice water leaking or pooling around the unit, you could have a loose fitting, failed valve, or worse – something internal. Either way, get eyes on it before the water finds your drywall.
- Weak Flow or Low Pressure: A clogged inlet screen or scaled-up aerators can restrict water flow enough that the unit won’t fire at all.

Why has my tankless water heater stopped making hot water?
If your tankless water heater has stopped producing hot water, the usual suspects are ignition failure, a tripped breaker, gas supply issues, a clogged inlet filter, or a flow sensor that can’t detect demand. Scale from Central PA’s hard water is the hidden culprit behind a lot of these issues. Pronto’s tankless diagnostic offer will find the actual cause so you’re only paying to fix what is actually broken.
Why does my water go hot, then cold, then hot again?
This is known as the cold water sandwich, and it’s a common bother that many homeowners face. Sometimes it’s just cool water sitting in the pipes between uses. But if it happens every time you turn on the hot water, you’re likely looking at a failing flow sensor or scale interfering with the heat exchanger. A Pronto plumber can tell you which problem you are dealing with and usually fix it on the spot.
How often should a tankless water heater be flushed in Central PA?
With our limestone-hard water, once a year is the minimum, and twice a year is often best. Professional maintenance and flushing protects the heat exchanger and keeps your efficiency up. Pronto’s VIP plan handles all the reminders and the scheduling for you, protecting your investment for up to 10 years, so you don’t have to keep track of it yourself.
Should I repair my tankless water heater or replace it?
Tankless units are built to run about 20 years with the proper care and maintenance, so repair usually makes sense for a younger unit with one isolated problem. If your unit is older or the heat exchanger has failed, replacement is usually the smarter move. When you work with the pros at Pronto for your tankless water heater service, you can rely on an honest diagnostic report and upfront pricing on all your options.
